I have taken the SAT biology test twice. I got a 660 the first time and a 640 the second time. I am not happy with these scores at all and I want to retake the test. Will colleges not like seeing that I took the test three times? Would it be better to not take the sat biology test a third time and get a very good score on the AP Biology exam?
Few schools even require SAT subject tests. I would have quit taking the Bio test after the 1st time.
Can you? Yes. Should you? No.
If the college requests 2 Subject Tests (and few do), consider other subjects. Otherwise, just move on.
AP scores are not used in lieu of Subject Test scores for 99%+ of US universities. One will not offset the other.
