What SAT subject tests should I take?

I am a high school senior looking to apply to top schools. I have a 3.9/4.0 gpa, and a 2290 on my SAT. I’m taking my subject tests in October. I’ve been preparing for the Spanish one, but I don’t know which others to take. Freshman year I got a 720 on the Biology subject test but think I should try to get a higher score on a different test. How important is it to take a math sat ii?

Take them in subjects you like and are good in. If you’re good at math, take the Math II one. You probably don’t even need more than 3 tests, but check the requirements of the schools you’re applying to. 720 is good. In fact, I’d be glad if I got a 720!

It’s only important for some schools if you are applying to a math/engineering major.
Take them in subjects you feel you will do well in.
