3. The use of blank or lined paper for rough working is allowed; squared paper, calculators and measuring instruments are forbidden.

4. Do not expect to finish the whole paper in the time allowed. The questions in this paper have been arranged in approximate order of difficulty with the harder questions towards the end.
