Common GCSE Mistakes

❌ WRONG: Common mistake related to equations with brackets
✅ CORRECT: The correct approach and why it works
❌ WRONG: Another typical error students make
✅ CORRECT: The right method with clear explanation
❌ WRONG: Forgetting to show working in 'show that' questions
✅ CORRECT: Always write every step clearly for full marks

GCSE Exam Tips

  • Read carefully: Make sure you understand what the question is asking before you start
  • Show your working: Even if you know the answer, write down the steps for method marks
  • Check units: Always include units in your final answer if the question involves measurements
  • 'Show that' questions: You must prove the given answer by showing complete working
  • Time management: Don't spend too long on one question - move on and come back if needed
  • Check answers: Use the last few minutes to check your answers make sense
  • Grade boundaries: Grade 5 = strong pass, Grade 4 = standard pass - know your target!
