Dear Student
This tutorial letter contains information on the examination, discussion class problems and
solutions, as well as a previous examination paper with its model answers. Try to work
through all the evaluation exercises, assignments, discussion class problems and the previous
examination paper when you prepare for the examination. It is also a good idea to work
through the assignments of the first semester. The solutions to the first semester’s
assignments can be found under Announcements on myUnisa.

It is better to sort out your problems before the examination than to repeat the module next
semester.
Finally, well done you have made it up to here! We wish you everything of the best with the
last hurdle, the examination. I hope that you have enjoyed the module. It was a pleasure
assisting you in this module. Best wishes for the future.
Kind regards
