When to take SAT?

<p>I've already taken the SAT twice (the first time I only got somewhere in the 1800's...the second time I got a 2010).</p>

<p>I'm going to be a senior this year and the school I'm applying to early, I'm pretty sure of getting in because my GPA is .5 higher than the average and my SAT score is ~400 points above the average.</p>

<p>However, I'm particularly worried about GWU and UVa. I'm applying to both of them regular decision and I was wondering what month I should take it (October, November, December).</p>

<p>I haven't done much practice (only two full tests) since the 2nd SAT, which I took in June, so I'm hesitant to take it in October. I'm mainly trying to get my math and CR reading scores closer to the 700's, if not in the 700's, since my writing is already a 760. </p>

<p>So, when should I take it? And do you have any tips for M and CR?</p>
