Work out how much time you have per mark for your exam questions and only spend that amount of time answering each part of each question.

For AQA-A:

• Part (a) on an AS question paper is only worth 6 marks, no matter how good your answer is!
• Part (b) is also only worth 6 marks
• Part (c) is worth 60% of the question

If you do not answer part (c) you can only get 40% of the marks for that question - assuming the answers for (a) and (b) are perfect. 40% is only just a grade E
