Retake Bio?

<p>I'm currently a junior and so far I've taken Math IIC, Chem and Bio. This morning I checked to see that I got 800 in Math and 780 in Chem, but last October I took Bio and got a 740. I want to apply to ED to Columbia, a school that said it will take the 2 best scores on any subject test. But do you guys think it's worth studying Bio again over the summer and try to push it to a 750+ in November? I'm also retaking the SAT in October. Got 2200+ first time.</p>

<p>Thanks all</p>

<p>Don’t bother retaking a 740 especially if your other SAT IIs are so high.</p>

<p>thanks; any more advice?</p>

<p>I agree with rainbowrose, especially since by Novemeber you’ll probably be so stressed w/ senior year you won’t have enough time to really prep, and by then you’ve probably already forgot a lot of bio from this year. It would probably be a better use of your time to write some kickass essays instead :D</p>
