720 Biology--Retake?

<p>Hello everyone!
I took the Biology M SAT II this past October and got a 720, and although it relatively isn't too bad a score, I'm not too satisfied with it. I'm a pretty good student and I'm hoping to aim for a decent college (shall I say, shamelessly, Yale). </p>

<p>I'm a sophomore in high school and quite honestly, biology is and was never my best subject. I'm more into art/writing and math/logic (weird, I know), rather than subjects that require a lot of memorization (biology or history).
The only reason I took the SAT II for biology was because (it sounds bad, I know) all of my friends were taking it, and it gave me the feeling that it was required for college or something. Of course, I realize that I was never interested in biology or that field, and I now have a 720 stuck to me.
I'm wondering if I should just leave it alone and get better scores in the subjects I am better at (Math 2, Chem), or if I should retake it and somehow get a higher grade (which I am seriously doubting because I am terrible at memorizing hundreds of words).</p>

<p>Thanks in advance!</p>
