My AP1&2, and Micro teacher both dropped the lowest test grade, but if your scores are usually about the same then it really doesnt matter. Even if you did bad on one test, you should know why you did bad and correct yourself for future tests. Oh and both of my teachers curved also, but only if you were close to the next grade. For example if I had an 89 average, it would be curved to an A-, but if I had an 87 it would stay as a B+. I am starting nursing school in the fall and I am nervous also, questioning whether I will be able to hack it or not. Nervous or not I am going to give it 100%, just like when I started my pre req's I told myself I had no other choice but to get A's because that is what is needed to get into the program, and that is what I did. While in the nursing program I am going to have the same attitude, I am going to give it my all and become the best nurse that I can be, there is no other option. Good luck to you, you will be great!!
