Who this is for
A student meeting a chapter for the first time, catching up on one they missed, or checking they really know it before a test. Open AI Tutor and use Teach me a chapter on the right.
Overview
A guided lesson walks you through a chapter's own learning outcomes — the list of things the syllabus says you must be able to do — one at a time. Each one is taught in your chosen teaching style and closed with a short checkpoint, so you know you've got it before moving on.
Starting a lesson
- Pick a chapter from your own board-and-class or exam subjects.
- From My Library — a lesson built from your own uploaded material or lecture. If you've confirmed which chapter it covers, the lesson follows that chapter's outcomes and teaches from your material first; otherwise the steps are drawn from the material itself.
Explore or Mastery
| Mode | How it moves |
|---|---|
| Explore | You move on after each checkpoint. Get at least one of the two right and the step counts as learnt; otherwise it goes on your list to revise. |
| Mastery | You move on only when you get both checkpoint questions right. Each retry has new questions. After three tries it moves on and the step goes on your list to revise. |
You can switch mode at any point in the lesson.
Readiness and the quick check
Before the first step:
- Before you start shows the earlier chapters this one builds on, each marked from your Learning Genome (green, amber, red or not tested), so you can shore one up first.
- The quick check asks one question per step. Answer it right and that step is marked already knew and skipped — you can still open it. Or choose Skip — teach me everything.
Each step
- The lesson — the idea, a worked example and the rule, in your style, ending with a Remember: line. Where the chapter lists a mistake students commonly make here, the lesson names it and the fix.
- Didn't get something? Ask — a question about this step, answered in context.
- Try this — from the chapter — a practice problem written and checked by our team, where the chapter has one for this step. Work it on paper; the worked answer opens after the checkpoint.
- Checkpoint — two multiple-choice questions, marked with the reasoning.
If you already know a step, Skip this step moves on (it counts as one to revise).
Finishing
When every step is done, press Finish the lesson. You get:
- A checklist of every outcome — already knew, learnt, or to revise.
- Your checkpoint answers recorded against the chapter in your Learning Genome, with the ones you missed in your Error Book, and XP.
- Flashcards for what you missed, built from those steps' lessons, which come back for review with spaced repetition.
Pausing and reviewing
Lessons save after every step. Leave whenever you like; the lesson waits under In progress (“Step 3 of 7”) and resumes exactly where you stopped. The numbered rail at the top of a lesson opens any step, including in a finished lesson, to go over it again.
Limits
- 10 new lessons a day.
- Lessons and checkpoint questions are written by AI from the chapter; the “Try this” problems are hand-checked by our team. If a checkpoint question looks wrong, report it with the flag under it after marking.
