Should I take the January SAT? Please help.

I have a 2230 from one sitting the 2014 December SAT test. (740CR, 720M, 770W, 11E) and I’m considering taking the test again January 2016. I’m a senior right now and am planning on applying to Duke, Vanderbilt, WUSTL, NYU, and the UCs. I have a 750 on Math II and an 800 on Chinese.

Should I take the test in January? Which schools will still receive my updated scores, and will it affect my application? Thanks.

That’s a good score for the colleges you’re applying to(over the 75th percentile). I suggest you focus on ECs now
