The use of a pocket calculator is permissible in the examination for ALL Chemistry modules.
Note that students who have NOT passed Physical Science at Matriculation level must pass CHE111 and 112 BEFORE they register for any other
modules in Chemistry.
Students who register for modules in Chemistry are referred to 5 in connection with PRACTICAL WORK.
Mathematics (MAT111, 112 (or 101 and 102)) forms part of Chemistry as a major subject. You are advised to register for these modules in your first
year of registration.
A BA student who has passed the three CHL-modules on first level does NOT qualify for direct admission to modules in Chemistry on second-year
level for the BSc degree. There are no further modules in Chemistry for BA students.

Practical Work
5
Practical work is an integral part of Chemistry and is covered in CHE104.
Details of compulsory practical courses and required practical facilities, practical examinations, and exemptions from practical work and practical examinations
will be found in Part 7 of the Calendar and 5.1 below.
CHE104
Students must attend a compulsory laboratory course at Unisa or at another centre identified by the Department of Chemistry, Unisa during the year of
registration.
Admission to the laboratory course is restricted to students who have satisfactorily completed a specified number of assignments as specified by the
Department of Chemistry.
The final examination mark is based on the marks obtained for the assignments, the practical work and practical tests.
CHE221–224
Students registered for these modules must attend a compulsory laboratory course in Pretoria lasting 12 days ((3 days per module) (2x Monday to
Saturday)) during the year of registration (except in cases where exemption has been granted in terms of 5.1). See dates under 5.2.
Admission to the laboratory course is restricted to students who have either:
(i)
satisfactorily completed a specified number of assignments in the corresponding theoretical modules;
or
(ii)
have already passed the corresponding theory module.
CHE321–324
Students registered for these modules must attend a compulsory practical course (one week per module) in the Unisa Chemistry laboratories in Pretoria
during June when the entire practical syllabus will be covered. Admission to the practical course in a module is normally only granted to students who
obtain at least 50% in the first assignment of that module.
Practical examinations for these modules will be completed during the compulsory practical course in June. See Sc6 in Part 7 of the Calendar in connection
with the retention of credit.
5.1
EXEMPTION FROM PRACTICAL WORK AND PRACTICAL EXAMINATIONS
Exemption from the compulsory practical work and practical examinations may, with the written approval of the Head of the Department of Chemistry, be
granted to students who have previously completed or who are attending an equivalent practical course at a recognized university or specially approved
14
academic institution, provided that the results achieved are satisfactory. The responsible person at the university or academic institution concerned must
submit a mark to the Head of the Department of Chemistry at Unisa for the practical work, indicate the year in which it was obtained, and certify that it is the
student’s own work. This mark will be regarded as an examination mark.
Exemption from the practical examination will only be granted for a maximum of two successive calendar years after the year in which the mark was
obtained.
All applications for exemption must be made in writing, and students must be registered for the module for which the exemption is requested.
