Multiple choice questions
Multiple choice questions appear in both exam papers, and at both tiers. Multiple choice questions are asked as questions, often starting with 'What is 鈥' or 'Which of these 鈥'.
You have four options to choose from in a multiple choice question. You must only choose one of these options, by writing your answer (A, B, C, or D) in a box.
It may help to reject any answers that you feel are obviously wrong, so that you can focus on choosing the right answer.
