I got a 690 in math and a 630 in reading and I received a LOA and BFE and i live near a naval base so i thought my area would be very competitive. So I would say, you should always try to improve if you can, but I think your scores are good. However, i think SATs aren’t really my forte, so other stuff that probably helped me is that I’m taking 6 AP classes senior year, I’ve already taken 5, and got all 4s and a 5 in BC Calc, I’m tennis captain, fccla president, and received both presidential and congressional nomination. So, you shouldn’t dwell too much on SAT, if you’re other areas are satisfied.
