Points of emphasis
Use terminology correctly. Identify the key points in your answer. Be concise; donít waffle.
If you are asked to apply your knowledge to a particular problem, consider the problem carefully. There are likely to be aspects of it that are intended to provoke particular responses from you.
If asked to draw on your experience or expertise, remember to indicate those aspects that are relevant to the question.
While an encyclopaedic knowledge of Sommerville and Davisís textbooks will help you, to obtain a first-class mark (grade A) you will almost certainly need to demonstrate how you can apply that knowledge.
