Ahh I know exactly what you mean I also chose this as my planet unit and I'm kind of dying from the science, I'm only keeping it cause it doesn't have any exams and also I forked out $30 for the textbook . I think you can change units without having to pay any money before the 31st of March, however I think the last day to enrol in internal units is this Friday. So if you really want to change you should act fast.
Mhmm I'm probably gonna just sell mine on the page...IM sure theres someone out there that needs it hehe
Does anyone know who I go talk to if I need some help to see if what I'm doing is ok for my degree?
