<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>
