How to Use a Formula Sheet
- Save or print the sheet — keep it on your study desk for daily reference.
- Test yourself — cover the formulas and try to write them from memory.
- Group related formulas — connect formulas that build on each other for better recall.
- Use each formula in problems — apply it to at least 2–3 questions to make it stick.
Quick Revision Tips
- Short daily sessions — 15 minutes of formula revision every day beats one long session a week.
- Formula cards — write one formula per card, shuffle and test yourself.
- Teach someone — explaining a formula to a friend helps it stick.
- Last-day strategy — the night before the exam, review only your formula sheet. Do not attempt new problems.
