I don't think it's that bad. I'm in the RN program in TH, and here, they take in A&P I and II, Algebra, Psych and Dev Psych, Comp, Microbiology, and Advance Physiology, plus the TEAS. I had an A in all the prereqs except Algebra (B). I hadn't even taken Physiology yet (took it after I was accepted and made an A) so there was 32 points I didn't have. I was accepted in the first group, so don't give up. One B is not going to hurt, but, if I had a C, I'd go ahead and retake the class.
