What to study next

Computed from your own progress, in your browser. Nothing on this page is sent anywhere, and the rules behind every recommendation are listed at the bottom so you can check the coach’s working.

A concept counts as mastered at 80%, blending completion with your quiz and exam scores.

Tell the coach where you are heading and it will point at the earliest thing standing in your way.

Your next three steps

Your plan

A week-sized path toward your goal, computed here in your browser and rebuilt around whatever you have already finished. Ticks fill in on their own when you complete a lesson, solve a challenge or pass a quiz — the plan reads your progress, it never asks you to claim it. Changing your goal above redraws the road ahead and leaves finished work alone.

Your skill map

Prerequisites run left to right. Everything to the right of a gap is waiting on it.

  1. 1. Revise. A lesson you finished but quizzed below 70% on comes first — everything downstream of it is built on that footing.
  2. 2. Advance to your goal. If you have set a goal, the coach shows the earliest unmet prerequisite for it, not the next lesson in the list.
  3. 3. Practise. If you have read about gates but never built a circuit, building one beats reading the next page.
  4. 4. Advance. Otherwise, the next lesson whose prerequisites you have all met.
  5. 5. Explore. Last, a visualization for something you have read about but never actually seen move.

The ranking is deterministic and runs entirely offline — the same progress always produces the same three recommendations.
