* HD High distinction, with marks in the range 85-100 per cent.
* D Distinction, with marks in the range 75-84 per cent.
* C Credit, with marks in the range 65-74 per cent.
* P Pass, with marks in the range 50-64 per cent.
* PII Division II pass (frequently called `P2 pass'), with marks in the range 45-49. This grade counts for the purpose of the academic record of the student, but no more than one P2 grade may be counted in a pair of sequential subjects if being used as prerequisites for a higher level subject or subjects. Regulation 10.3 defines how many P2 passes may be counted towards the degree. Students should note that, whereas they may be awarded any number of P2 grades during their whole course of studies, regulation 10 restricts them, in qualifying for the award of their degree, to counting not more than twenty-four points of subjects at P2 level, with not more than sixteen points at levels one and two, and not more than twelve points at level three. Students must prepare to repeat the work in the other P2 subjects if they are to be counted towards qualifying for the degree.
* PR Provisional grade, with marks in the range 40-49. Used for first-year first-semester subjects only. Where a student does not achieve a pass in a first-semester subject which forms part of a pair of sequential subjects, that student may be awarded a provisional grade (PR). Such a student will be permitted to proceed to a second-semester subject which forms the other part of a pair of sequential subjects. A grade of PR will be altered after the end of second semester of the same year to one of P, PII or NN. Amendment of the PR will be achieved as follows. (i) It will be amended to a grade of P where the second-semester marks are sufficiently above 50 to allow a deduction of marks to bring the first-semester results up to 50 by addition of the marks subtracted from second-semester results. Only marks sufficient to bring the first-semester result up to 50 will be deducted from the second-semester result. (ii) It will be amended to a grade of PII where second-semester marks are not sufficient to bring the first-semester result up to 50, but are sufficient to bring them up to 45 by addition of the marks subtracted from second-semester results. Only marks sufficient to bring the first-semester result up to 45 will be deducted from the second-semester result. (iii) It will be amended to a grade of NN where second-semester results are not sufficient to allow a deduction to bring the first-semester results up to 45. In this case the marks will remain unchanged. In the cases of (i) and (ii), the second-semester grade will not be reduced below 50 unless it is already P2. Second-semester P2 grades will not be reduced to NN.
* NN Fail result, with marks in the range 0-44 per cent.
BSc Honours and MSc Preliminary assessment grades
Honours results are notified in the following grades without marks:
* HI Honours, first class;
* HIIA Honours, second class A;
* HIIB Honours, second class B;
* HIII Honours, third class.
Whereas an MSc (Preliminary) program does not lead to a course award, results are notified as follows:
* SFR (equivalent honours grade) meaning that the student has satisfied the program requirements at an equivalent honours grade of HI, HIIA, HIIB or HIII as indicated within the brackets;
* NE Not examinable, ie a code to indicate that the program is not complete in the current year;
* NN Fail result.
Special consideration and deferred examinations
Students in any year of an undergraduate degree whose attendance or performance at any examination is prevented or gravely affected by illness or other serious cause may apply for special consideration or for a special examination (commonly called a deferred examination). Applications must be made on the appropriate form obtainable from the Faculty of Science office. Applications must be submitted not later than forty-eight hours after the conclusion of the student's last examination in the relevant examination period. The form must be accompanied by supporting evidence including a medical certificate if illness is involved. Students who wish such information to remain confidential must consult an Academic Adviser.
Special examinations are normally taken in late January (this applies to both first and second semester subjects).
Special consideration applications are referred to examiners, who take the application into account when marking papers, and to the board of examiners, who consider the application when assessing the student's results as a whole.
