There is this idea that applicants somehow have a better chance with an 800 than a 760 (your example) and it just isn’t true.Your daughter has more than met any benchmark for any school, and after that it is about other things. Spending time on raising the score is silly, but some people do it- maybe because they want to be able to say they got perfect scores. But for admissions, it really, at this point, with a 760 already, is better to spend time on extracurriculars.
