Lessons & Homework

Lesson Types

Your teacher creates three types of lessons:

Lesson Statuses

Every lesson moves through a series of statuses:

For Homework, click "Send to teacher" on the bottom panel to submit. Your answers are saved — you do not need to stay on the page. The teacher verifies the submission and may leave written feedback.

Teacher's Assignment Note

When your teacher assigns a lesson, they may include a note with context, instructions, or preparation tips. This note appears:

• on your Dashboard in the "Lesson Starting Soon" banner
• in the calendar when you hover or click on the lesson
• in the email notification you receive about the assignment

Completing a Lesson

1. Open a lesson from your Dashboard, My Enrollments, or My Library page
2. Work through the content and exercises — progress saves automatically
3. When finished, click "Save & Finish" on the bottom panel (or "Send to teacher" for homework)

For a detailed walkthrough of the lesson interface, see Use Case: Completing a Lesson.

Learning Actions in Read-Only Lessons

Some lessons are read-only because they are finished, locked, timed out, or opened for review. You cannot change answers in a read-only lesson, but learning tools may still be available.

Select text in the lesson to use actions such as:

• Translate — view a translation and add useful words to your vocabulary.
• Listen (Text-to-Speech) — hear selected text read aloud by a native-sounding AI voice.

Listen (Text-to-Speech) is billed at 1 token per 15 characters with a minimum of 1 token, and supports up to 100 words per request. If the selected text is too long or the action is unavailable, the button is disabled with an explanation.

Viewing Feedback

After review, you receive a notification and the lesson status changes to Verified. A "Teacher Feedback" banner appears above the editor toolbar with the teacher's comment.

Past Lessons

The Past Lessons page gives you a timeline of lessons you already attended or completed. Use it when you want to review feedback, reopen a previous lesson, check homework history, or find a lesson summary.

You can filter the timeline by lesson type, such as class lesson, homework, or exercise. Opening a lesson card shows the details, including feedback, homework information, time spent, transcript status, and summary status when available.

If a teacher sends you a link to a specific past lesson, the page opens directly to that lesson and scrolls it into view.

Post-Lesson Summary

For live lessons where your teacher has turned on the summary feature, you receive a post-lesson summary shortly after class ends. It is written in your native language and covers:

• what you practiced and the new vocabulary introduced
• how you did on exercises, speaking, and writing during the session
• any homework your teacher assigned and its due cadence
• suggestions on what to review before the next class

The summary is delivered by email and is also visible on the lesson page under the Summary tab. If you prefer not to receive it by email, turn off the Lesson Summary toggle in Profile & Settings → Notifications. The in-app view remains available regardless.

Time Limits

Some lessons have a time limit set by your teacher. When a lesson is timed, you will see a countdown timer in the bottom toolbar showing how much time you have left.

How It Works

• The timer only runs while the lesson tab is active in your browser. Switching to another tab or minimizing the window pauses the timer.
• Time is saved to the server automatically. If you close the browser and come back later, the timer resumes from where you left off.
• When 15% of your time remains, the timer turns amber as a warning.
• When time runs out, all exercises become read-only and an amber banner appears: "Time is up -- your answers have been saved."

Tips for Timed Lessons

• Check the timer when you start so you know how much time you have
• Pace yourself -- answer the questions you're confident about first
• Don't worry about switching tabs briefly (the timer pauses)
• Your answers save automatically as you work, so nothing is lost if time expires

Exam-Style Lessons

Some lessons are set up as exam modules. Before you begin, you may see a start screen explaining that answers will be hidden while you work.

During an exam-style lesson:

• you may have a countdown timer
• answer feedback can stay hidden until you submit
• audio tasks may limit the number of plays
• writing tasks may ask for a word range and allow handwriting upload
• speaking tasks may show an automated score and examiner feedback

When you finish, click Submit exam. If the timer runs out first, your current answers are saved and the lesson becomes read-only.

Answer Resets

Some lessons allow you to reset your answers and try exercises again. When available, you'll see a "Reset answers" button in the editor toolbar.

• Available -- you can click "Reset answers" to clear your responses and start over. A confirmation dialog asks you to confirm before resetting.
• Not available -- the button is hidden. This is common for homework assignments where your teacher wants to see your original work.

Whether the reset button appears is controlled by your teacher's lesson settings. If you don't see it, it means the teacher has intentionally disabled it for that lesson.

Lesson Lockdown

Your teacher can lock a lesson at any time during a live session. When locked:

• All exercises become read-only (you cannot change your answers)
• A blue banner appears: "Your teacher has locked this document"
• Your existing answers are preserved

Lockdown can also happen automatically when a timed lesson expires. In that case, you'll see an amber banner instead.

If your teacher unlocks the lesson or resets the timer, you can continue working normally.

When a Teacher Cancels or Deletes a Lesson

Your teacher can cancel or delete a lesson at any time — including a lesson that has already passed.

• If the lesson was canceled, the lesson card moves to the Canceled state and stays in your history.
• If the lesson was deleted, the lesson card is removed from your schedule and lesson list.

If you were billed for the lesson, the cost is refunded automatically — you do not need to ask for it. Refunds appear in your token transaction history. If something looks wrong, reach out to your teacher first.

Locked Lessons

Some courses release lessons gradually — on a schedule, after you finish the previous one, or when your teacher manually unlocks them. Before a lesson unlocks, you see it as locked in your lesson timeline on Dashboard, My Enrollments, and My Library:

• The card appears greyed out with a lock icon next to the type label.
• The title is plain text — clicking it does nothing.
• Hovering (or tapping on mobile) the lock badge shows an unlock hint — Unlocks on {date} when your teacher set a fixed schedule, or This lesson will unlock soon for sequential or manual releases.

When the lesson unlocks, you receive a Lesson unlocked notification with a message like "Unit 3 — Past Tense is now available" — click it to jump straight into the lesson. The notification arrives immediately when your teacher unlocks it, or on the scheduled date for date-based unlocks.
