Who teaches you

Every lesson has a named AI teacher and a mentor who keeps you on track. Both are AI, and every screen says so.

  • AI Super Professor · MathematicsMarcus Ellery

    I start from what you already understand and make every new idea grow out of it. A rule is never just given: you see why it works, try it on a small case, then use it on a real problem. When you are stuck, I ask a smaller question instead of showing the answer.

    Mathematics is not about numbers or computations. It is about understanding.

  • AI Super Mentor · MathematicsIvana Petrović

    I do not teach the lessons; Marcus does. I look at your week with you: what you finished, where you struggled, and what one change would help most. Then we write a short plan you can keep.

    The best way to understand a concept is to teach it. The second best is to apply it.

How lessons run

Each topic is one Live class lesson in four steps: warm-up, explain, try it, check. The AI tutor gives hints, not answers, and waits for the learner to think.

  1. Warm-up

    A quick question to recall what you already know.

  2. Explain

    The AI tutor explains one idea at a time, in plain words.

  3. Try it

    You work a problem with hints, not answers handed over.

  4. Check

    A short check shows what stuck; a teacher sees the result.

Assessment

Short checks after each lesson and a unit check at the end of each unit. The AI drafts marks; a human teacher reviews them and signs the term.

The same year elsewhere

For orientation only: a starting check sets where lessons begin.
