Failing a Class in Community College not related to my Major for Pre-Med

The reason for the failed CC class was because I missed the final exam, which was worth 20% of my grade. I realize that this is not an excuse, and that this is my fault. I got an A in Psych 1, and I realize that Psych is a required pre-req for some med schools now. So I should plan on re-taking Psychology at my 4-year university instead of at the CC during the summer? @WayOutWestMom
