B is great for that class. I got a b in a&p as well and got in first round. If you are usually an a student in nursing school you will probably be a b, b+ student. That is still ok. I was an A student b4 nursing school. I still get a lot of a's but not in every class. I am still am honors student just no 4.0 lol
Good luck and dont be so hard on your self. you did great.
