South Africa right?

You need to contact UNISA or your Matriculation Board direct. We are FIXYA .com, a website to fix broken things in NORTH AMERICA!

We are not a school.

Hello, Juliet -

If you reside in South Africa, I recommend you contact UNISA (University of South Africa) directly.

This is the link to the Contact Us web page for the UNISA Department of Social Work:
http://www.unisa.ac.za/sites/corporate/default/Colleges/Human-Sciences/Schools,-departments,-centres,-institutes-&-units/School-of-Social-Sciences/Department-of-Social-Work
I suggest you make a telephone call and speak with someone in the department.

OR . . .

Are you asking about the University of South Australia (UniSA)? If so, see the information here:

Either way, Fixya.com is intended for questions and answers on repairing _things_. I am a librarian by profession and am answering from the USA.
