My Problem I have at Varsity College

I registered this year at Varsity College for a B.ED course and they gave me a list of subjects i must register for at Unisa, so i registered those subjects but all of a sudden every one registered for an extra subject PST 104F(Teach prac) and this was not in my list to register and i never got told anything about this teaching prac, and when i heard students talking about it I just thought its something to do with the course and didnt know you had to register it. now i am unable to register this subject at Unisa until next year, now i dont know what to do because we have a 5 week teaching prac coming up but now i cant submit it to unisa and i will have to do it next year.
