3. Submit
Video and text lessons, interactive blocks, quizzes and audio or writing tasks appropriate to each lesson. Fullscreen viewing for focused learning.
4. Receive feedback
Feedback from Lizzie (AI) with pronunciation, grammar and context suggestions. Your teacher can review scores and comments.

You receive priority corrections, a more natural version and a direct recommendation to record or submit again.
6. Measure progress
Activity, attempt, score and feedback history to follow your progress.
