retaking sat subject tests

<p>i took math II and bio M last year as a sophomore:
mathII: 750
Bio: 740
Should I retake one or both of these tests? My top choices of schools are MIT and williams so I know I have to have everything in my favor. But do college really care if you go up at most 500-600 points? would I have to report all scores?
I already got a 5 on the AP Bio exam so I don't think that one would be worth re-doing because they already know I'm proficient. But I'm taking the AP Calc exam this year and I don't know whether I am going to get a 5 or not so I'm kinda worried. Plus MIT stresses math a lot so it could be dangerous to have an score like that. what do you think?</p>

<p>I would retake those, honestly. Especially if you want to get into MIT and Williams. Shoot for 760+ on Bio and 780+ on Math Level 2.</p>
