The coursework requires the submission of a single report which contains two elements which together contribute 50% to the overall module mark. The marks shown indicate the maximum possible marks that each individual element contributes to the final module mark. The finished report should be submitted to the resource centre (Prospect Building, St Peter’s) by the hand-in date shown above.
