How much linear algebra is needed for a course on group theory?

I’m planning to take a first course on group theory this fall. I took a basic computational linear algebra course last fall, but I learned absolutely nothing. The course was extremely easy, and the exams were the practice exams with numbers changed. I’m regretting not studying the material properly… Literally all I can remember is how to rref a matrix, add/multiply matrices and find determinants through cofactor expansion. I don’t think I could explain what a linear transformation is…

How much is this going to bite me in the ass? I’m a CS major and I’ve already had two terms of discrete math plus a very proofy algorithms course so I’m not particularly worried on the proof front.
