Exam Technique Reminders

Tip	Detail
Show ALL working	Every step earns method marks — even if your final answer is wrong
Check command words	"Calculate" = get an answer; "Prove" = show full algebraic working; "Explain" = words needed; "Estimate" = round first
Use the marks as a guide	A 3-mark question needs at least 2-3 lines of working
Non-calculator paper	Paper 1 has no calculator — practise mental and written methods
Read the question twice	Many marks are lost from misreading what's actually asked
Units matter	Include units in your answer where the question specifies them
