Bring weak material back sooner
If a session exposes a genuine gap, do not wait three weeks simply because the rotation says so.
Free tool
Revision planner.
Give it an exam date and a realistic amount of weekly study time. It creates a rotating plan with repeated encounters rather than pretending every topic can be revised once and filed away.
Your suggested rotation
Your plan will appear here. It is intentionally simple: repeated practice, sensible spacing and room to react to what you get wrong.
How to use it
The timetable is the starting point, not the boss.
Do questions, not just preparation
Use at least part of each session for retrieval, explanation or problem solving before checking support.
Mix old and new
Once the basics are secure, include older material so you practise choosing and recalling methods.
