Study Tips

  1. 1

    Keep an error log: write down every mistake, why it happened, and redo the problem a week later.

  2. 2

    Show every step of your working — most exams award method marks even when the final answer is wrong.

  3. 3

    Memorize key formulas by using them repeatedly, and know exactly which ones are provided on the formula sheet.

  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.

Common Mistakes to Avoid

  • Dropping negative signs and misapplying the order of operations under time pressure.

  • Skipping steps in working, which throws away method marks when the final answer is wrong.
