Testing 8/15

I am testing 8/15 with a goal score of at least 510. However, I took BP 1 and AAMC unscored and got around a 500 both times. I am trying my best to grind uworld and then I'll be doing AAMC q pack and section bank but is there enough time? Should I reschedule? I am already so anxious and stressed but I also do not want to deal with studying while in school because I know I will have other commitments. Please help :(
