Overview

The core element of the course is a research project that involves 9 weeks laboratory work, starting one week prior to the beginning of Semester 2, and production of a thesis. Assessment is on the basis of the performance in the laboratory, the thesis, and the project seminar. Students are expected to spend a minimum of 25 hours in the laboratory each week. Two research tutorials will be organised by academic staff and will be assessed by examination at the end of the Semester. Tutorials will be held at regular intervals with the tutor appointed by the Head of School.

Structure

2 four-hour research tutorials and 2 one-and-a-half-hour seminars plus 9 weeks project work at 25 hours per week.

Assessment

1st Attempt: 1 two-hours, 1 three-hours and 1 four-hours examination at end Semester 2 (70%); in-course assessment (30%).

Resit: 1 two-hour, 1 three-hour and 1 four-hour examinations.
