Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
Simple recall questions are usually worth one mark. They often have command words like 'Give', 'State', 'Name' or 'Identify'. Some questions may ask you to state two things, rather than just one, and will be worth two marks.
Structured questions, with command words such as 'Describe' or 'Explain', will be worth two or more marks:
if you are asked to describe something, you need to give an account but no reason
if you are asked to explain something, you must give reasons or explanations
More complex structured questions will be worth three to five marks. They include questions with complex descriptions and explanations, questions in which you need to compare and contrast two different things, or calculations with several stages.
The mark schemes given here may show answers as bullet points. This is to show clearly how a mark can be obtained. However, it is important that your answer is written in a logical, linked way and in full sentences.
