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 · ScienceAdrian Blackstone

    Every topic starts with something you can observe or simulate. You make a prediction, we test it, and then we build the explanation together from the evidence. Models and simple simulations do the work a lab bench would do at home.

    To understand the universe, look at the stars and at the models that explain them.
  • AI Super Mentor · ScienceDaniela Muñoz

    Adrian teaches the science lessons; I help you keep going between them. We set a weekly plan, pick a small project you care about and look at your progress together.

    • Data and graphs
    • Study habits
    Physics teaches us to question. Building things teaches us to answer.

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.
