Should I drop AP Statistics?

Well, I'm not completely sure that I understand what you are asking, but if I were you I would try to have more than 3 academic cles if you want to major in science. Science is as academic as it gets, and many academic courses are you used in it. Math, even statistics, is important in a science based career. Maybe talking this through with a guidance counselor would be worthwhile. Good luck on making the difficult decisions.
