I am very interested in CRNA school. Ive been an ICU nurse for 2.5 years now. In preparation, I signed up for an online medical biochemistry class through the university of new england.... I am in way over my head! I can't remember anything from undergrad chem, even though I got an A in the class. Im just feeling really discouraged and am tempted to drop the class. It is so hard to work and find the time to study!
