I got all A's until A&P II - got a B in that one and a B in micro as well. They were hard classes. I worked my tail off and felt proud that I made a B. I graduate from a BSN program in May - took prerequisites at a community college. So, don't think that one B is going to decrease your chances of getting into a school. They look at all kinds of other things - and different schools do it differently. For my school they looked at the GPA from A&P I, II, Micro, Human Growth &Dev. together as "nursing prep" classes and then they looked at the entrance exam score and overall GPA. There was some kind of a points system. Those who had the most points got in. And, I got in at both my prereq school (ADN program) and the BSN program - it was harder to get into the ADN program!! 2500 applicants for 40 spots! As far as that grade being a predictor for how you will do in nursing school - maybe it is. I have gotten all A's and B's so far. My GPA is not as high as it was but it is still pretty good. And, when I graduate with my 3.59 GPA I will get the same degree I would have gotten with a higher GPA. Study hard and learn all you can in A&P - you will need that knowledge base for your future classes. Pathophysiology is just around the corner! : ) Good luck!
