Each technical module is examined by a separate one-and-a-half hour examination paper in term 3 (hereinafter referred to as ``the June examinations'', though there may in fact be examinations before the start of June). Each of these examinations contains three questions; each candidate is required to attempt two of these. The Professional Issues module is examined by a one hour examination in May.
For Honours courses (including joint honours), the examinations must be passed at the first attempt, although failures on individual papers are permitted. That is, students failing to obtain an overall Honours pass mark in the June examinations will not be permitted to enter CS4, even if they resit the examinations.
A candidate who fails the Honours examination in June may nevertheless be awarded a pass at the Ordinary degree level without taking the resit examinations if a performance commensurate with an Ordinary degree has already been obtained. For students who fail to achieve a pass at the Ordinary degree level in June, resit examinations for the Ordinary degree take place in September. Students needing to resit should consult their Directors of Studies to make sure they are registered for the examinations. Students are not expected to resit papers that they passed in June, as the mark from the June examination will be carried forward.
