Should I change professions?

I'm currently in A&P 1 and about to fail. The way my class is set up the physiology portion of the class is worth 75% of the final grade, while the anatomy lab makes up the other 25% and you must pass both sections. In the physiology section we have a quiz every week, a take home quiz every two weeks, and 3 exams. The anatomy lab consists of 4 practicals in which there are ten models, five labelled parts (bone/muscle/nerves/digestive) per model, and a woman with a stop watch telling you to move every two minutes. The reason I ask is because I can't imagine being able to juggle this class with a full schedule. I have a high 90 in the physiology portion of the class, but I can't manage to memorize the hundreds of terms for the anatomy practical. I can't memorize things that I can make sense of, and memorizing the anatomy portion seems near impossible. I know school is a lot of hard work and I'm not concerned about that, but how much of nursing school is learning about how the body works versus memorizing random bones? Should I change professions or do things change after the A&P's?
I never had to do that kind of stuff in nursing school. It's a hurdle. Either get over the hurdle -- or go around it by taking another route (another school). Don't let the fear of one particular class determine your life's work.

In my opinion, nursing school was much easier than the A&P classes that I had to take beforehand.
