Study Tips
- 1
Work through past papers under timed conditions — familiarity with question style is half the battle.
- 2
Teach the material to someone else (even an imaginary student) — explaining exposes weak spots fast.
- 3
Use active recall: close your notes and write down everything you remember, then check the gaps.
- 4
Review class notes within 24 hours of each lesson — quick review dramatically improves retention.
- 5
Use homework as diagnostic practice: redo any problem you got wrong until it feels easy.
