Failing A&P II. Am I doomed?

So, long story short, I’m an LPN, and have been for 7 years. Started going back to school about two years ago, and because I went to vocational school I started as a transfer freshman with no credits. Needless to say, I’m retaking ALL of my classes. I’ve passed with all A’s and B’s with the exception of stats and microbio, which I got C’s in. So now, onto my dilemma.

I had a super shitty semester both in and out of school. Working outside of my profession so I can get through school, my sister got arrested on some pretty serious charges, taking care of an elderly grandmother, and going to a state school with little to no regulation on the professors because they’re so desperate for staff. Im taking A&P II this semester and most of the students (including myself) have all had very similar grades. First test was high 40’s-low 50’s. Second test was the same. Third test we all miraculously had 80’s. There’s only about 3 students out of 30 who aren’t failing as miserably as the rest. Now, we have a final tomorrow with absolutely no study parameters. Cumulative with drawings. When asked what we should concentrate on he simply said “everything”. Mind you, my school makes students take A&P II prior to being accepted into the nursing program so all of us still need to apply for it. I think I’m totally fucked. I’m really afraid that if I have to retake this class that I won’t be accepted into a nursing program. Am I totally fucked? Has anyone else failed a science and made it into a program? Please let me know. (Btw, I’m in NJ if that makes a difference)
