I recieved the OCT 3 sat results today. My scores are 720CR/800M/660WR (2180 ) . My previous Sat scores were 770CR/690M/620WR (2070) (For superscoring). I am an International (Indian) student aiming for cornell,caltech,princeton and a few other top colleges (Applying for 100% aid). I checked the average (25 percentile/75 percentile scores) of most of these collleges and found that the scores were around 700-800.
My question is: Is it worth taking the SAT again to improve my writing scores and is there time for doing so? (I am a senior student and I am taking the subject SATs in november, so I will have to take the SAT in december)
