Taking The SAT: How Many Times?
Ask a dozen college admissions counselors how many times you should take the SAT and you could get a dozen different answers. My favorite answer to that question is the always-maddening "It depends."
Beyond that, in general, I have more often than not advised my clients that a three-test maximum seems to work best. Obviously, if you're in the high 700s across the board on your first try, then you should probably thank your lucky stars that you nailed it and move on to other challenges. Don't be obsessive and try to bump those 780s into 800s. In my view, that's greedy and, of course, you could always do worse. It's the diminishing returns thing.
