I recently took the 3R aamc exam given free online. I got a solid 9 on the bio section with no study time. Although this is not the ultimate score I would like to achieve, it seems like a good start. My main question and reason for posting this thread is to gain an idea as to how good this is. If I feel that I am solid in biology, I will substitute a few classes I have scheduled right now for humanities and social sciences. What do you all think? Thanks for your insight!
