Probably true, but not where the SAT is concerned. If you get a 1580 SAT on your first try, no need to retake! In all seriousness, retaking a standardized test takes time and money. At some point, that cost overrides the marginal additional benefit from retaking -- and /or you may end up doing worse on one or both elements. USNA also puts greater emphasis on your math SAT.
So, for example, if you score a 650V, 700M and retake getting a 670V, 700M, you have to ask whether it's worth it to retake. You probably aren't going to suddenly jump to 800/800. So, if you get a 680V and 710M, is that really going to mean that much more in terms of your overall application?
There's no one size fits all answer. But I would not suggest retaking in the (mistaken) belief that USNA will be persuaded by the number of times you took the test even if your improvement is marginal (or non-existent). Also, consider the potential impact on your civilian schools (those that want you to take a standardized test). How do they treat multiple attempts -- for example, do they consider only your most recent scores?
My son took it once. He got 800 math and his superscore with ACT wasn’t 1600, but it was close.
With his grades, etc - I do not believe his chances got any better taking it again. He didn’t want to so he didn’t.
I don’t even know how the SAT is converted to WCS points, and what the additional wcs would be, if any.
DS is trying to figure out test strategy going forward. Last fall, he took the PSAT and scored in the top 1%, then took the ACT and SAT scoring solid scores with room for improvement (I believe ACT32? Math was 35, SAT 1480? Math 720) With limited dates to retest (not conflicting with SS, sport schedule and other commitments), he is looking for advice on the best strategy for improvement. He is confident on his knowledge of the material covered but believes his problem lies in his reading speed. He did not have enough time to complete the reading section, then had trouble letting it go and spending his energy and focus on the rest of the test sections. Three of his top colleges accept super scores, one does not. He is able to take the ACT twice this spring. Should he try to complete the entire test to the best of his abilities that day or split the sections and focus between the 2 test dates?
