Information • The total mark for this paper is 90. • The marks for each question are shown in brackets – use this as a guide as to how much time to spend on each question. • In the question marked with an asterisk (*), marks will be awarded for your ability to structure your answer logically, showing how the points that you make are related or follow on from each other where appropriate. • The list of data, formulae and relationships is printed at the end of this booklet. Advice • Read each question carefully before you start to answer it. • Try to answer every question. • Check your answers if you have time at the end. • You are advised to show your working in calculations, including units where appropriate.
