Videos and some interface labels may appear in their original language.

Exercise Creator: User Guide

This guide explains how to use Slingui’s exercise creation page. It helps teachers and content creators build exercises manually or with support from AI Chat, review the result in the preview, and save the exercise safely.

Button, tab, field, and interface message names appear in this guide in the UI’s original language, English, such as AI Chat, Exercise Overview, Edit Question, Save, and Review and finish.

Overview

The exercise creation page lets you create, edit, duplicate, review, and save custom exercises for your school.

With it, you can:

• Create an exercise from scratch using Exercise Overview and Edit Question.
• Create an exercise with help from AI Chat.
• Generate images for questions.
• Upload images and audio.
• Generate audio with one or two voices.
• Generate reading passages for Reading exercises.
• Automatically classify grammar, vocabulary, and difficulty with AI.
• Save progress with Save.
• Publish or save as unpublished using Published.
• Review and save the final exercise with Review and finish.
• Find previously created exercises in My exercises.
• Duplicate an existing exercise with Duplicate exercise.

This guide does not cover Journeys and Pathways.

Understand the Main Screen

The Exercise Creator screen has two main areas.

Settings Column: on the left, containing the creation and editing tabs.

Preview Column: on the right, showing a preview of what the student will see.

Header

At the top of the left column, you will see the New Exercise title and a menu with additional actions.

Useful menu options:

• Settings: opens global image and audio settings.
• Restart: restarts the current exercise. The interface warns that unsaved progress will be lost.
• My exercises: opens the screen for finding and editing previously created exercises.
• Duplicate exercise: lets you load a copy from an exercise ID or link.

Tabs

Exercise creation is organized into three tabs.

Tab	Purpose
AI Chat	Create or update the exercise by chatting with AI.
Exercise Overview	Edit general exercise information and manage the question list.
Edit Question	Edit the content of a specific question.

Footer buttons

Two buttons appear at the bottom of the left column when you are in Exercise Overview or Edit Question.

Save: saves current progress as a draft. Use it during creation to avoid losing work.

Review and finish: validates and saves the final exercise. Use this button when the exercise is ready.

These buttons are hidden while you are using AI Chat.

Preview

The preview shows a simulation of the exercise.

When you are in Exercise Overview, the preview shows the exercise’s start screen with:

• cover image or default banner
• title
• description
• number of questions
• CEFR level
• Let's Start button

When you are in Edit Question, the preview shows the selected question with a layout similar to the student experience.

The preview may display:

• Back
• Skip
• Confirm
• multiple-choice options
• written-answer field
• audio player
• question image
• reading passage
• Start recording button for Record Voice

Important: the preview is only a simulation. Actions such as clicking options, Confirm, or Start recording do not record actual answers.

Global Settings

Open Settings in the top menu to access Global Settings.

These settings define the defaults used when generating images or audio. You can still adjust images and audio individually for each question.

Image Generation

In Image Generation, you configure defaults for AI-generated images.

Default Style sets the default visual style.

Options:

Option	Recommended use
Vector Art	Clean, simple, educational illustrations.
Photorealistic	Realistic-looking images.
Cartoon	Colorful, more playful visuals.
Editorial	Conceptual illustrations with an editorial look.
Low-poly 3D	Simplified 3D visuals with geometric shapes.

Default Aspect Ratio sets the default image format.

Options:

Option	Format
1:1 (Square)	Square image.
4:3 (Landscape)	Standard landscape image.
16:9 (Wide)	Wide landscape image.

Remove Background by Default generates an image with a transparent background when possible. The interface itself states: Note: This increases image generation time.

Audio Generation

In Audio Generation, you configure defaults for AI-generated audio.

Default Voice sets the default voice. The Alternate (Achernar/Achird) option alternates voices between questions, which helps with exercises involving multiple lines of speech or listening variety.

Default Speaking Rate (0.25 - 4.0) sets the speaking speed. Use values close to 1 for natural speech. Lower values slow speech down. Higher values speed it up.

Save or restore settings

Use Save Settings to save your preferences.

Use Restore Defaults to return to the interface defaults.

AI Credits

Some Exercise Creator actions use AI and consume credits. These credits are an internal unit used to track monthly usage of features such as exercise, image, audio, and text generation, and automatic classification.

Usage is not a fixed amount per exercise. It depends on the type of action performed and the volume processed, such as prompt length, response length, number of images generated, number of audio clips generated, and the length of texts used for audio or classification.

Actions that consume credits

These Exercise Creator actions may consume AI credits:

Interface action	What happens
AI Chat	Generates or updates the exercise plan.
Requesting images in AI Chat	Generates images for questions that have an image description.
Regenerate images in chat	Regenerates images for questions with imageDescription.
Generate in Image	Generates an image for the current question.
Generate in Audio	Generates single-speaker audio for the current question.
Create Dialogue and Generate Audio	Generates two-speaker audio.
Generate Dialogue Lines	Uses AI to create structured dialogue lines.
Generate Reading Text	Generates a formatted reading passage.
Select terms automatically using AI	Classifies the exercise’s grammar, vocabulary, and difficulty.
Automatic classification after AI Chat	Analyzes the generated exercise and fills in grammar, vocabulary, and difficulty when possible.

Each generation counts separately. For example, if an exercise has 5 questions and you request images for all of them, generating the exercise plan consumes credits and each generated image may also consume credits.

Actions that do not consume AI credits

These actions do not use AI directly and do not consume AI credits:

• Manually editing the title, description, questions, answers, and options.
• Adding questions with + Add Question.
• Reordering questions.
• Selecting Mark Question as Completed.
• Manually uploading with Upload Image, Upload in Image, or Upload in Audio.
• Copying media with Copy from....
• Saving a draft with Save.
• Saving the final exercise with Review and finish.
• Opening, searching for, or editing exercises in My exercises.
• Duplicating exercises with Duplicate exercise.

Note: attaching a file or pasting a URL into AI Chat prepares that material for use by AI. Preparing the attachment does not directly record credits, but generating an exercise using that material may consume credits.

How credits are calculated

Slingui calculates credits from the actual usage returned by AI providers.

In practical terms:

• generated or analyzed text is charged based on input and output tokens
• images use image-generation usage data
• audio uses voice-model usage data
• automatic classification uses input and output tokens
• longer texts, longer prompts, and longer responses tend to consume more credits
• generating multiple images or audio clips increases total usage

You do not need to calculate this manually. Use the AI Usage page to track recorded usage.

Monthly limits

The system may have a monthly credit limit for the user, the school, or both.

Before performing an AI action, Slingui checks whether the user or school has already reached the configured monthly limit.

If the limit has already been reached, new AI actions may be blocked. Depending on the action, the interface may show a generation error message, such as a failure to generate content, an image, or audio.

The check takes place before the AI call. This means an action can start while there is still allowance available and, after completion, cause the monthly total to exceed the limit.

How to track usage

Use the AI Usage page to track credit usage.

To open it:

1. Use the side navigation in the exercises area.
2. Click AI Usage.
3. Choose the month in Select Month:.
4. Choose the year.
5. Use Refresh to update the data.

The AI Usage Summary screen shows:

• Total Credits Used
• daily usage chart
• breakdown by feature, such as Create Exercise and AI Tutor
• daily details
• details by user, feature, and usage type

Click a chart bar in Daily Usage to see details for that day.

Report scope

What you see in AI Usage depends on your role.

Role	What the screen shows
Student	Personal AI usage.
Independent teacher	Usage by the teacher and their students.
School owner	Usage across the entire school, including teachers and students.
School teacher	Usage by the teacher and students assigned to them.

The screen itself displays a message explaining the scope, such as Showing your personal AI usage. or Showing AI usage for your entire organization (teachers and students). (usage across your entire school, including teachers and students).

Best practices for saving credits

Review your prompt before sending it in AI Chat.

Clearly specify the language, level, number of questions, and exercise type to avoid unnecessary regeneration.

Generate images only after the questions are close to their final version.

Generate audio only after reviewing Audio Script.

Use Copy from... when multiple questions can share the same image, audio, or reading passage.

Avoid clicking Generate multiple times while the first generation is still running.

Use Save to save progress manually. Save does not consume AI credits.

If an AI action fails

If an AI action fails, try:

• reviewing the prompt
• reducing the size of the request
• generating fewer images at once
• generating audio after reviewing the scripts
• checking the AI Usage page
• trying again later
• contacting your school’s administrator if you suspect the monthly limit has been reached

Some calls may consume credits when the AI provider returns a response, even if you later decide not to use the result. For this reason, review content before requesting new generations.

Create an Exercise with AI Chat

AI Chat is the quickest way to get started. It collects a few preferences, generates an exercise plan, and fills in the structure for you to review.

Even when using AI, always review the final content. The interface itself displays the warning: Slingui AI can make mistakes. Please consider reviewing exercises created.

Step by Step

1. Open the AI Chat tab.
2. Answer the initial question about the exercise’s target language.
3. Choose how many questions the exercise should have.
4. Choose the CEFR level.
5. Specify whether you want to generate images for the questions.
6. Describe your exercise idea.
7. Wait for the plan to be generated.
8. Review the exercise in Exercise Overview.
9. Adjust each question in Edit Question.
10. Use Review and finish when ready.

Quick suggestions

The chat displays suggestions at certain points.

Examples:

• Languages such as English (US), Spanish (Spain), and Portuguese (Brazil).
• Numbers such as 3, 4, 5, 10, and Any.
• Levels such as A0, A1, A2, B1, B2, C1, C2, and Any.
• Yes and No answers for image generation.
• Ideas such as Travel vocabulary, Business meeting, Daily routine, Present Perfect grammar, and Restaurant dialogue.

You can click a suggestion or type your own answer.

Use attachments and links

AI Chat accepts attachments and URLs to help AI create content based on existing materials.

You can attach:

• images
• videos
• audio
• PDFs
• .txt files

The current local file limit is 50 MB.

You can also paste links into the chat field.

YouTube links, such as youtube.com and youtu.be, are treated as YouTube content.

Other http or https links are used as reference URLs.

What AI generates

Depending on your request, AI may fill in:

• Exercise Title
• Description
• Language
• Skill
• Question Type
• Open Questions
• questions
• correct answers
• options
• audio scripts
• image descriptions
• reading passages for Reading
• grammar, vocabulary, and difficulty through automatic classification

If you requested images, AI attempts to generate images for questions that have imageDescription.

If questions have audioScript, the interface attempts to generate audio automatically.

After generation, the chat usually directs you to open Exercise Overview to review the exercise.

Update an exercise with chat

After an exercise has been generated or loaded, you can continue using AI Chat to request changes.

Example requests:

• Make the questions easier.
• Change the topic to airport travel.
• Turn this into a Multiple Choice exercise.
• Add more business vocabulary.
• Regenerate images.
• Regenerate audio.

When you request a content update, AI returns the complete updated exercise structure. Always review the result in Exercise Overview and Edit Question.

When you request image or audio regeneration, the interface uses the current Global Settings.

Prompt best practices

A good AI Chat request includes the objective, audience, level, and question type.

Example:

Create a B1 English (US) listening exercise with 5 Dictation questions about checking into a hotel. Use natural travel vocabulary and generate audio.

Another example:

Create an A2 Spanish (Mexico) Complete the sentence exercise about daily routines. Focus on present tense verbs and include one blank in each question.

If you already know the question type you want, mention the UI name, such as Text Answer, Multiple Choice, Put words in order, Complete the sentence, Dictation, or Record Voice.

Create an Exercise Manually

Manual creation takes place mainly in Exercise Overview and Edit Question.

Use Exercise Overview to configure the exercise as a whole.

Use Edit Question to edit one question at a time.

Each Question Type has its own answer fields.

Examples:

• Text Answer uses Correct Answers (Acceptable variations).
• Multiple Choice uses Options and one option marked as correct.
• Put words in order uses Sentence to Order and Scrambled Words.
• Complete the sentence uses Correct Answers and _ in the text.

Mark Question as Completed

At the end of Edit Question, there is a Mark Question as Completed toggle.

This toggle helps you track which questions you have already reviewed.

It does not replace the final validation in Review and finish. Even when marked as complete, a question must still meet the required rules for the selected type.

Skills

Skill describes the main skill the exercise develops.

It does not replace Question Type. For example, a Grammar exercise can use Multiple Choice, Text Answer, or Complete the sentence.

Skill	When to use it	Notes
Grammar	When the objective is to practice grammatical structures.	Combine with Complete the sentence, Text Answer, Multiple Choice, or Put words in order.
Listening	When students need to listen to answer.	Use audio for each question. Works particularly well with Dictation and dialogues.
Reading	When students need to read a text before answering.	Enables the Reading Text section in Edit Question.
Pronunciation	When students need to listen and repeat.	Usually paired with Record Voice. In the system, this skill is saved internally as speaking.

Grammar

Use Grammar for exercises focused on a structure, verb tense, question form, word order, or another grammar point.

Examples:

• present simple
• past simple
• modals of obligation
• articles
• conditionals
• comparison

Even in a grammar exercise, also select Vocabulary and Grammar Point (Primary focus), as these fields are required to save.

Listening

Use Listening when audio is essential to answering.

Examples:

• students listen to a sentence and choose the correct option
• students listen and write what they hear
• students answer questions about a dialogue

Recommendations:

• Fill in Audio Script clearly.
• Generate or upload audio for each question.
• Use Dictation when students need to transcribe.
• Use dialogues with 2 speakers for communicative situations.

Reading

Use Reading when students need to read a text to answer.

This skill enables the Reading Text section in Edit Question.

Recommendations:

• Use short texts for A0, A1, and A2.
• Use longer texts or texts requiring inference for B1, B2, C1, and C2.
• Combine with Multiple Choice, Text Answer, or Complete the sentence.

Pronunciation

Use Pronunciation when the objective is for students to listen and repeat.

The most common type for this skill is Record Voice.

Recommendations:

• Keep sentences short.
• Make sure Question Text, Script / Correct Answer, and Audio Script make sense together.
• Generate clear audio to serve as a model.

Question Type

Question Type defines the student’s answer format.

Every exercise must have a single question type. The interface and final save reject exercises containing questions of different types.

Summary of types

UI	Internal type	Allows Open Questions	Main use
Text Answer	write-answer	Yes	Short or open-ended written answers.
Multiple Choice	choose-answer	No	Choosing between options.
Put words in order	write-put-in-order	Yes	Ordering words to form a sentence.
Complete the sentence	write-complete	Yes	Filling in blanks marked with _.
Dictation	dictation-write-answer	No	Listening and writing what was said.
Record Voice	read-listen-repeat	No	Listening and repeating while recording your voice.

The correct option is visually highlighted.

Example

Field	Example
Question Text	Choose the correct sentence.
Options	She goes to school., She go to school., She going to school.
correct answer	She goes to school.

Important differences

Multiple Choice uses options that are visible to the student.

This type does not allow Open Questions, because grading depends on a correct option.

Final validation

To save Multiple Choice:

• there must be at least two nonempty options.
• a correct answer must be selected.
• the correct answer must exactly match one of the options.
• Open Questions must be disabled.

You can also drag chips to rearrange them or edit each chip manually.

Example

Field	Example
Sentence to Order	I love apples
Scrambled Words	apples, love, I

In the preview, students see a word bank and type their answer.

With Open Questions

Put words in order can be used with Open Questions.

In this case, the system does not save a final correct answer. However, the scrambled words must still be present.

Final validation

To save Put words in order without Open Questions:

• Sentence to Order must contain the correct sentence.
• Scrambled Words must contain at least two items.
• internally, scrambled words must be separated by commas.

• answers are saved as empty.

Dictation

Use Dictation when students should listen to audio and write exactly, or almost exactly, what they hear.

Main fields

• Question Instruction
• Script / Correct Answer
• Alternative Answers (Optional)
• + Add an answer
• Audio Script
• Generate or Upload in Audio

The Script / Correct Answer field is synchronized with Audio Script.

If you change the main text, the interface copies the value to the audio script.

Example

Field	Example
Script / Correct Answer	I would like a glass of water.
Alternative Answers (Optional)	I'd like a glass of water.
Audio Script	I would like a glass of water.

Important differences

Dictation requires audio or an audio script because students need to listen before answering.

This type does not allow Open Questions.

Final validation

To save Dictation:

• Open Questions must be disabled.
• there must be a correct answer or a script that can be used as the answer.
• script or audioScript is required.
• alternative answers are accepted as additional answers.
• all questions must have the same type.

Record Voice

Use Record Voice when students should listen to a sentence and repeat it aloud.

This type is particularly useful for Pronunciation.

Main fields

• Question Instruction
• Question Text
• Script / Correct Answer
• Audio Script
• Generate or Upload in Audio

The Script / Correct Answer field is synchronized with Audio Script.

In the preview, students see the Start recording button.

Example

Field	Example
Question Text	The weather is beautiful today.
Script / Correct Answer	The weather is beautiful today.
Audio Script	The weather is beautiful today.

Important differences

Record Voice is not an open-ended question. The objective is to repeat an audio model.

AI attempts to keep answer, text, and audioScript identical for this type, unless you request something different.

Final validation

To save Record Voice:

• Open Questions must be disabled.
• there must be an answer, text, or script indicating what students should repeat.
• script or audioScript is required.
• all questions must have the same type.

Open Questions

Open Questions is useful when there is no single correct answer.

Use it for:

• personal answers
• free production
• reflections
• short creative writing
• open-ended comprehension questions

Allowed types:

• Text Answer
• Put words in order
• Complete the sentence

Blocked types:

• Multiple Choice
• Dictation
• Record Voice

When Open Questions is enabled, the final save forces question answers to an empty list.

This means the question will have no correct answers saved for automatic validation.

Save Progress with Save

Use Save to save progress while you are still creating.

This button does not perform the final exercise save. It works as a draft.

When you click it, the interface may show:

• Saving...
• Saved!
• Error

You must be logged in to save progress. If you are not, the interface displays Login required.

Use Save before long breaks or before making major changes to the exercise.

Save the Final Version with Review and finish

Use Review and finish when the exercise is ready for its final save.

When clicked, the interface validates the exercise and displays messages if anything is missing.

If the initial validation passes, the Save exercise? confirmation appears with the Save Exercise button.

After a successful save, the interface displays Saved and finished.

What happens during the final save

During the final save, the system:

• validates required fields
• validates consistency between the exercise and its questions
• validates rules specific to each Question Type
• validates language, skill, level, and difficulty
• validates vocabulary tags
• validates grammar points
• validates images and audio
• copies final media to permanent storage
• saves the exercise
• updates selected packs, if any
• removes the progress saved as a draft

Final Validation

Final validation ensures that students can use the exercise correctly.

Some validation takes place immediately in the interface. Other checks take place on the server during Review and finish.

Required exercise fields

Before saving, fill in:

• Exercise Title
• Description
• Language
• Skill
• Question Type
• Level
• Difficulty
• Vocabulary, with at least one tag
• Grammar Point (Primary focus), with at least one item
• at least one question

Consistency rules

The exercise must also meet these rules:

• all questions must have the same Question Type
• all questions must have the same Open Questions state as the exercise
• Multiple Choice, Dictation, and Record Voice cannot use Open Questions

Validation by type

Type	Main validation rules
Text Answer	Requires at least one correct answer, unless Open Questions is enabled.
Multiple Choice	Requires at least two options and a correct answer, and that answer must be one of the options.
Put words in order	Requires a correct sentence when not open-ended and at least two items in Scrambled Words.
Complete the sentence	Question Text must contain _, and a correct answer is required when not open-ended.
Dictation	Requires an answer or script, and script or audioScript is mandatory.
Record Voice	Requires an answer, text, or script, and script or audioScript is mandatory.

Media validation

Images and audio are also validated during the final save.

For images:

• accepted formats include PNG, JPG, WEBP, GIF, and BMP
• SVG is not supported
• the image must be valid and decodable
• the image must not be corrupted
• the image must be no larger than 10 MB

For audio:

• the file must be in a supported audio format
• the audio must not be corrupted
• the audio must have a valid duration
• the duration must be between 0.2 and 300 seconds
• the audio must be no larger than 25 MB

For media URLs:

• they must use http or https
• they must be accessible during saving
• temporary browser URLs, such as blob:, are rejected

If there is a media error, the interface attempts to show a friendlier message, such as Cover image, Question 1 image, or Question 2 audio, to indicate where to make the correction.

Duplicate exercise

Use Duplicate exercise to create a copy of an existing exercise.

Step by step:

1. Open the menu at the top of the page.
2. Click Duplicate exercise.
3. Paste an exercise ID or link into the Exercise ID or link field.
4. Click Duplicate.

The interface accepts links with the exerciseId parameter, including playground and assign links. The modal states: Accepted links include playground and assign URLs with an exerciseId parameter.

When duplicated, the loaded exercise no longer has its original ID. When you save it, it will be created as a new exercise.

Packs selected in the original exercise are not retained in the duplicate.

If the ID or link is incorrect, the interface displays Unable to load exercise.

Restart

Use Restart to clear the current exercise and start again.

When clicked, the interface asks Restart exercise? and states All unsaved progress will be lost.

Confirm only if you really want to discard anything that has not yet been saved.

My exercises

My exercises lets you find, review, and edit exercises created by your school.

For users with administrative permission to create official content, My exercises lists official Slingui exercises.

Open My exercises

Step by step:

1. Open the menu at the top of the page.
2. Click My exercises.
3. Use search, filters, or cards to find an exercise.

The header may show a description such as:

• Search and manage exercises created by your organization. (exercises created by your school).
• Search and manage official Slingui exercises.

Search

Use the Search exercises... field to search by title, description, or tags.

Search updates automatically as you type.

Filters

My exercises provides the following filters.

Filter	Purpose
Language	Filters by language family.
Skill	Filters by Grammar, Listening, Reading, or Pronunciation.
CEFR	Filters by level from A0 to C2.
Grammar	Filters by grammar points.
Difficulty	Filters by Easy, Medium, or Hard.
Type	Filters by Question Type.
Vocabulary	Filters by vocabulary tags.
Author	Shows the fixed source of the listed exercises.
Pictures	Shows only exercises with an image.
Open Questions	Shows only exercises with open-ended questions.

Use Clear all to clear active filters. The Author filter remains set to your school or Slingui, because My exercises always lists this fixed collection.

Language filter

The Language filter works by language family.

Examples:

• selecting English searches en-US and en-GB
• selecting Spanish searches es-ES and es-MX
• selecting Portuguese searches pt-BR

You can choose only one language family at a time.

Changing Language clears the Grammar and Vocabulary filters.

Grammar and Vocabulary filters

Grammar and Vocabulary become available only after you select Language.

If you click Grammar or Vocabulary before selecting a language, the interface displays Select Language first.

This happens because grammar and vocabulary options depend on the selected language family.

Author filter

The Author filter is fixed in My exercises.

For regular users, it shows exercises from your school.

For official-content administrators, it shows Slingui exercises.

When you open the filter, the interface explains:

• My exercises always shows exercises from your organization. (exercises from your school).
• My exercises lists official Slingui exercises for admins.

Exercise cards

Each card may show:

• Published or Unpublished status
• title
• description
• vocabulary tags
• grammar tags
• CEFR level
• difficulty
• image icon when the exercise has an image
• number of questions, such as 5 qs
• Open questions indicator, when applicable

Cards for your school’s exercises may display the school’s visual identity.

Card actions

Open the three-dot menu on a card to see its actions.

Available actions:

Action	What it does
Open in playground	Opens the exercise in a new playground tab.
Edit exercise	Loads the exercise in the creator for editing.
Copy exercise ID	Copies the exercise ID to the clipboard.

When you use Edit exercise, the exercise loads in Exercise Overview.

If you are the exercise’s author, saving will update the same exercise.

If you are not the author, the exercise loads as a copy and the next save creates a new exercise.

Recommended Review Workflow

Before clicking Review and finish, carry out this review.

1. Check Exercise Title and Description.
2. Confirm Language, Skill, Question Type, Level, and Difficulty.
3. Check that Published is in the desired state.
4. Confirm at least one tag in Vocabulary.
5. Confirm at least one item in Grammar Point (Primary focus).
6. Open each question in Edit Question.
7. Check Question Instruction and the text visible to students.
8. Check answers, options, scripts, images, and audio.
9. Use the preview to simulate the student experience.
10. Regenerate any problematic media before the final save.
11. Click Save if you want to save progress before the final version.
12. Click Review and finish when everything is ready.

Best Practices

Choose Question Type before creating many questions, because the type applies to the entire exercise.

Use AI Chat to generate a first version, then review it manually.

Generate images and audio after texts and scripts are stable. This avoids regenerating media repeatedly.

Use Select terms automatically using AI after the exercise has enough content.

Keep Question Instruction simple and consistent across questions.

In Multiple Choice, avoid very similar options for beginner levels.

In Dictation, keep the audio faithful to Script / Correct Answer.

In Record Voice, use short, natural sentences.

In Complete the sentence, check that each question has at least one _.

In Put words in order, prefer Scramble Words over assembling the words manually.

Use Preview to check layout, images, audio, reading, and navigation between questions.

Use Save as a draft during creation and Review and finish only for the final version.

Common Problems

I cannot save: required fields are missing

Check that you have filled in:

• Exercise Title
• Description
• Language
• Skill
• Question Type
• Level
• Difficulty
• Vocabulary
• Grammar Point (Primary focus)
• at least one question

The interface says Correct answer required

A question without Open Questions is missing a correct answer.

Check the type being used:

• in Text Answer, add at least one answer in Correct Answers (Acceptable variations)
• in Complete the sentence, add at least one answer in Correct Answers
• in Multiple Choice, select a correct option
• in Put words in order, fill in Sentence to Order
• in Dictation, fill in Script / Correct Answer
• in Record Voice, fill in Script / Correct Answer

Multiple Choice, Dictation, or Record Voice will not let me enable Open Questions

This is expected behavior.

These types do not support Open Questions because they depend on an answer, audio, repetition, or a correct option.

Error in Complete the sentence

Make sure Question Text contains _.

Correct example:

She _ to school every day.

Error in Put words in order

Make sure there is a correct sentence in Sentence to Order and at least two chips in Scrambled Words.

Click Scramble Words again if necessary.

Image or audio error when saving

The media may be corrupted, inaccessible, too large, or in an unsupported format.

Try:

• generating the image again with Generate
• uploading another image with Upload
• generating the audio again with Generate
• uploading another audio file with Upload
• temporarily removing the media and saving again

Grammar or Vocabulary will not open in My exercises

Select Language first.

Then open Grammar or Vocabulary again.

I cannot find my exercise in My exercises

Try:

• clearing filters with Clear all
• checking the Language filter
• searching for part of the title in Search exercises...
• checking that you are searching in the correct school
• remembering that unpublished exercises appear as Unpublished

Duplicate exercise does not load

Check that you pasted a valid ID or a link with exerciseId.

If you are using a link, make sure it contains something like:

?exerciseId=EXERCISE_ID

The preview does not save answers

This is expected.

The preview is only intended to simulate the student experience during creation.
