Each Unisa qualification is structured in such a way that you need to pass a certain number of NQF level credits within a certain amount of time in order to graduate.
It is also very important that you manage your studies and are able to pass the number of NQF level credits for which you register each semester or year. Please take note of Unisa's admission and re-admission rules, and the Unisa rules for students.
Each qualification page provides guidelines on how to do this successfully.
