SAT Subject Tests - What to take?

Hi guys,

I’m currently registered for the SAT Subject Tests for Math II, Lit, and US History. US History and Lit I’m keeping for sure, but I’m thinking of switching out Math II for Bio E because I’ve studied hard for the AP Bio test and I think I know the material well enough to pull a 780-800 without much effort. Math, on the other hand- I’ve never cracked open a subject test for it so I really don’t know how much I could get done between now and June to pull an 800.

If I don’t take Math II now, I could just take it in October… Should I do that? Any insight would be appreciated. I’m planning on majoring in PoliSci, btw.
