Which SAT II science should I take?

I took math 1 and got a 740 but I heard it’s good to have both math and science the problem is idk which one to take. Should I take a couple on one day or just focus on one subject? I’m gonna take it in October and I will be a senior. I’ve taken bio in fresh yr Chen in soph and physics in junior yr. I’ll also be taking AP bio this year. Also is my math 1 score any good or are top colleges looking for perfect/near perfect scores?

Most colleges that recommend subject tests (with the exception of Georgetown, which looks for 3) want 2 subject tests. With this in mind, I would personally choose a single science to focus on (preferably the one that you are best at/is freshest in your mind) and aim for a high score on that.

Math II, despite having more in-depth questions than Math I, has a much more generous curve and, ironically enough, seems to be easier to score exceptionally well on, provided you know your stuff. 740 is a pretty good score in general, but if you want to improve your score, especially for top colleges, it really wouldn’t hurt to try Math II.
