I am currently a sophomore at Hunter College and I'm trying to hopefully apply to their nursing program this spring 2011, but the thing that keeps bothering me is the fact that I got a D in Organic chemistry, which I didn't think I deserved cause I know I did good on my final. The students complained about the professor because after we took the final, he wouldn't give us our grades & their were always errors when he graded our other exams. When people went to look for him he was nowhere to be found and wouldn't apply to emails or anything. When this was made know to the chem department all they said was keep emailing him. I've talk to the advisers and they said that if I retake the class and get a better grade, I'll be fine and I can apply to get into the nursing program. But I feel like even if I get an A, I might not get in because of that one D that screwed me over and it looks bad.I don 't know what I should do, I've been having anxiety attacks because I really need this it's always been my passion to be a nurse and also to have stable source of income to support my mom and the family because as of right now we're not making enough to get by. Would my chances be slim to none of being able to apply or getting accepted? Thanks so much.
