If i fail 2 classes out of the 33 credits i attempted is that still over a 75% passing rate?
It depends on whether you're talking about a loan vs. a bursary or scholarship, and whether the money's coming from the university, gov't, etc. If it's a scholarship or bursary, they could; depends on whether the rules state that you must achieve a certain GPA AND pass everything. If it's a straight student loan, I really doubt it.
If you did below 2.0. Though, you would likely be put on academic probation first and perhaps more than once before anything would get drastic. Just keep plugging away. :)
