Should I Retake this December?

<p>I took the SAT my first time this October and am trying to decide whether to retake in December, wait until January, or wait even further. I'm trying to get into a top school for engineering, and scored a 2250 the first time. I feel as if at this point, studying for an extra two months won't help much, especially since I'm trying mostly to boost my math score (I got caught on the wrong side of a wicked curve this October, so hit a 750). I studied for the October test over the summer, so I feel fairly prepared. Another plus is that the December one will be given at my school, so that should help a bit. Does anyone have any advice over whether I should retake, given my situation? The deadline is in less than a week, so I have to decide fast.</p>

<p>By the way, I'm a sophomore so I know that I have plenty of time to retake next year anyways, but I'd rather get it done now and focus on ACT next year since I'm already pretty prepared. </p>

<p>Also, does anyone have any idea if there really is a big difference between a 2250, 2300, and 2350? I'm trying to decide at what point to stop retaking. </p>

<p>Thanks for your help!</p>
