<p>OP: I think it’s if you have an increase of 200+ points in one section. This happened to me and my scores were flagged but I was cleared and my score was validated because 1) the tests were taken a few years apart from each other and 2) my SAT subject test record was strong (this is what was said by the CB person). They didn’t even need to look at my PSAT score which only corroborated the legitimacy of my higher score.</p>
