Is my SAT score good enough for the CTY program cause I got a 1620 in SAT.?

A 1620 on the SAT is an exceptionally high score. While the Johns Hopkins Center for Talented Youth (CTY) doesn't have a publicly stated minimum SAT score, a score that high would almost certainly qualify you for their programs. However, CTY considers more than just the SAT score. They also look at your academic record and other factors. It's best to check the CTY website for their specific requirements and application process.
