Can't say I am in the same situation as you, but I did take 1st Year Anthro. It was actually fairly fun and I managed to do a B-, which is amazing for me, considering I have no background in Bio, Chem, Anthro or anything of the like.
Also, welcome to MacInsiders. This is going to be the most helpful place for you. Trust me, this forum saved my life a couple of times (almost literally).
