When I started nursing school I came in with a 3.5 GPA. I was used to getting High A's or just barely a high B on all my tests, mind you, thats with a degree in chemistry and one in biology.
Nursing school has turned me into a flat out 3.0 student, and I have learned to just roll with the punches! Do your best, keep your nose to the books and I wish you all the luck! Dont get bummed with just one low grade.
