Study Tips

  1. 1

    Work through past papers under timed conditions — familiarity with question style is half the battle.

  2. 2

    Teach the material to someone else (even an imaginary student) — explaining exposes weak spots fast.

  3. 3

    Use active recall: close your notes and write down everything you remember, then check the gaps.

  4. 4

    Review class notes within 24 hours of each lesson — quick review dramatically improves retention.

  5. 5

    Use homework as diagnostic practice: redo any problem you got wrong until it feels easy.
