Exam Success Tips

  • Always show working: Even if you use a calculator, show the calculation setup
  • Check answers make sense: A 90% discount shouldn't give you more than the original price!
  • Read carefully: Is the percentage being added or subtracted? Is VAT included or excluded?
  • Use multipliers for efficiency: 1.15 for 15% increase, 0.75 for 25% decrease
  • Round appropriately: Money usually rounds to pence, percentages to 1 decimal place
