• Answer all questions.
• Write your answer to each question in the space provided.
• Do not use an erasable pen or correction fluid.
• You should use a calculator where appropriate.
• You may use tracing paper.
• You must show all necessary working clearly.
• Give non-exact numerical answers correct to 3 significant figures, or 1 decimal place for angles in degrees, unless a different level of accuracy is specified in the question.
• For r, use either your calculator value or 3.142.
• The total mark for this paper is 56.
• The number of marks for each question or part question is shown in brackets [ ].
• Otherwise indicated, marks once gained cannot subsequently be lost, e.g. wrong working following a correct form of answer is ignored (isw).
• Where a candidate has misread a number in the question and used that value consistently throughout, provided that number does not alter the difficulty or the method required, award all marks earned and deduct just 1 mark for the misread.
• Recovery within working is allowed, e.g. a notation error in the working where the following line of working makes the candidate's intent clear.
