If you didn't know, Unisa in Durban has there own in house lecturers that get lectures and notes every weekend or fort nightly. The lectures are purposely sheduled for after hours. It costs R100 for 3 modules a semester which is really cheap.
They offer lectures for alot of the modules. For computers they offer the following lectures :
CEM101-A
COS111-U
COS112-V
INF105-9
INF205-C
They offer other subjects as well.They need a minimum 15 ppl.So if u in Durban and are struggling with COS112-V and others pay the R100 and attend the lectures.
