Compare Revision Techniques for Exam Success

You have flashcards, mind maps, and past papers all suggested to you, plus a fixed number of weeks and a finite number of hours. This rates the main techniques on what the evidence says and builds a plan that fits the time you actually have. For students who want to spend their revision hours on what works, not what feels busy.

2. Explain in plain language why the two most effective techniques work (the key psychological mechanism behind each)
3. Give one practical tip for getting started with each of the top two techniques without needing special apps or materials

**Edge case handling:** If the student's exam requires essay writing rather than factual recall, adjust the advice to emphasise argument structuring and timed writing practice.
