Guys, it really depends what course ur doin. Im doin the BscIT course, and realised its a waste of money to get the textbooks. But a major tip is befriend someone in second year, then buy ur textbooks off them...
Jayz, yeah the library does have copies of some textbooks, but there are limits as to how long u can use em for (der).
As for the two people that want to transfer after first semester, it really depends where you want to change to. I know that if you want to transfer into an IT course, they only look at it in the beginning of every year (so you can only change after second semester)... but check with the faculty that you want to go into for more details - and i guess buying textbooks could help, because when u transfer, they look at ur previous semesters work along with other stuff.
