How Many Subject Tests?

Hi!

I am going to take the subject tests in October and it is my only chance to do well on the subject tests since I am a rising senior. I have never taken the subject tests before. Currently, I am planning on taking Math Level 2 and Biology. Would selective colleges be okay with only 2 subject tests? I am not sure if I should add Chemistry… The thing is, I’m not sure if I would do too well in Chemistry, so I was thinking of skipping Chemistry and allotting more of my time to Math and Biology so I can score high in those.

Thanks for all your help!

Two will be fine except for Georgetown. Math 2 and Bio are good choices
