what do you mean invalidated?
do they have a list of schools. Most, not all, superscore.
Some will look at individual sections.
Look at the schools you are applying to - in most cases they superscore, so they’ll only look at the highest scores.
in fact, on common app, where you list them, you list only the highest, etc.
DS has a 33.75. They’d need 3 more points to get to a 34.5 or 35.
Dang - DD has the exact same.
A 34 is FANTASTIC - but for Ivy, a 35 is better. Not sure the TV/film/writing that Ivy is necessarily best.
DS has room to go in science. DD math and science.
Kids study differently - some from a book, some online (Khan Academy), some from old tests. We sent ours to a private tutor - six sessions - they can “focus” on areas for you. Not cheap ($95 an hour) - for us it worked. Each kid is different in how they learn or access to budget, etc. When I studied for GMAT way back when, I bought a book and hammered on one section a day - like an hour a day and did more on the english than math because that was my weakness - and did far better than i could have hoped for. That worked for me - as i was self motivated. But each kid is different.
A couple years ago they talked about allowing kids to re-take one section. Not sure if it’s happening but I would take the entire section.
But again, look at each school’s view. For example, Dartmouth says:
If you submit multiple scores from the SAT or ACT, we will accept superscored testing, i.e. your highest section scores in either test, regardless of the test dates.
Cornell has programs that are test blind - won’t even look at your test.
