How many score 2400 on sat?

There's no single answer to how many people score 2400 on the SAT. The number varies from year to year and is not publicly released by the College Board in precise figures. A 2400 is a perfect score, and only a tiny fraction of test-takers achieve it. We're talking about a very small number, likely in the hundreds or low thousands annually, out of millions of test-takers.
