Should I take the AP Biology exam next year?

I'm a high school junior right now taking 6 AP classes. I don't like Biology at all but it's the only way I can take AP Calculus because my counselor messed up my whole schedule and it's too late to take other classes. And I don't see the benefits of taking the AP Bio exam next year in May. But wouldn't it be a disadvantage if colleges see that I didn't take the AP Bio exam and only took the class of it? I heard that MIT doesn't even give credits for AP Bio at all and it's not gonna be my major at college anyways so what's the point of doing it? And the crazy thing is that I'm also taking AP Physics C right now, it's both Mechanics and E&M. The funny thing is that next year, both AP Bio and AP Physics C exams are gonna be on the same day, on May 13, 2013. My school doesn't offer AP Physics C and I'm self-teaching myself right now, the point is, I don't want to risk too much because of AP Bio since I really want 5 on AP Physics. And one more thing, even if my major isn't Biology at college, will I still be required to take Bio in college? If so, during what year? The first year in college?
