Exam Technique

Before attempting the questions, remember these key principles:

Principle	Detail
Read the question carefully	Identify the command word (define, describe, explain, compare, evaluate)
Use technical vocabulary	The mark scheme rewards precise, subject-specific language
Answer for the marks available	A 2-mark question needs two distinct points; a 4-mark question needs four
Show your working	For calculation questions, show each step — you may get marks even if the final answer is wrong
Use examples	Where appropriate, give a specific example to support your answer
