A pass of at least 60% in CEM1C10 for CEM1B01 and 65% in CEM1C2E, CEM13CE for CEM1B01
Chemistry 1A10 and 1B01 for all second and third year modules
CEM2A10, CEM2A20, CEM2B10 and CEM2B20 for CEM3A20, CEM3A10, CEM3B20 and CEM3B10
Practicals
Practicals are compulsory for all modules in Chemistry. 1 x 3 hours per week: CEM1A10, 1B01, 1C10, 1D10 1 x 6 hours per week: CEM2A10, 2A20, 2B10, 2B20 CEM3A10, 3A20, 3B10, 3B20
Practicals form an integral part of the theory discussed in the modules.
A sub-minimum of 50% for practicals is required for admission to semester examinations in Chemistry.
Examination
Apart from the sub-minimum of 50% for practical work, the candidate must have a final semester mark (practical work + theoretical tests) of at least 40% for admission to the semester examination.
The final mark is the average of the semester mark and the examination mark. The final pass mark for a module is 50%. A sub-minimum of 40% must be achieved in the examination (irrespective of the semester mark) to pass the module.
Tests, Tutorials and Practicals
1. Tests, tutorials and practicals are compulsory and count towards the semester mark. If an assessment opportunity of any kind is missed due to illness, an original medical certificate for a valid medical condition plus the Application for Deferred test/final assessment MUST be completed by a reputable general practitioner and must be handed in not later than 3 days after the missed practical or test. Failure to do so will result in a mark of zero being allocated. In case of other reasons for not attending an assessment opportunity an appropriate certificate or affidavit must accompany the Application for a deferred test. The Department may reject the application on grounds of insufficient justification.
2. A sub-minimum of 50% for practical assessments is required for admission to the exams in all Chemistry Department modules.
3. A student will only be allowed to miss one practical per module with valid documentation as set out in (1) above. If more than one practical is missed, the student will get a “Practical Incomplete” grading and will not be allowed entrance to the examination.
4. A student repeating a module will only be given exemption for the practical component of that module if 50% for the practical work was obtained in the previous year.
5. In the determination of the module semester mark the mark attained in the theoretical assessment is given a weight of approximately 75% and the practical mark a weight of
