How low can grades go for colleges to revoke your acceptance?

I may be ending up with one C. I have three B’s and three A’s. That’s not enough for colleges to revoke their acceptance right? Is it only when you have a C average?

You should be fine! I just got into Penn State’s BFA scenic design program last night with a 2.89UW GPA and was admitted for Fall at University Park! Let me tell you, that I got in with 2 C-'s, 3 Cs, a lot of B-'s, B’s, and B+'s and 4-5 A’s. The C’s and B’s represented a good amount of my core classes…so you are fine! It really comes down to what you have to offer and what you can and are willing to learn! It also depends on what major you are applying to.

PSU doesn’t even look at senior year grades. So all they want to know is that you graduated.
