What you do here
Pick a subject, a curriculum and a pace, and the path is laid out as lessons rather than as a syllabus checklist. A lesson is built around the specific step you could not make, and it will not hand you the answer to get you moving — it gives you the next move.
How it works
One engine decides what you open next, and the two surfaces that answer that question — your home and your path — both ask it rather than holding their own opinion.
