I’d say there are 2 things to think about here. One is application strategy. More important, though, is a finding schools where she’ll thrive.
There are plenty of kids who are excellent students who don’t test well for one reason or another. So less than stellar scores don’t mean a kid won’t be a decent BS student. At the same time, the SSAT does test something that helps students succeed which , imo, is ability to process quickly. The latter is a helpful, sometimes critical, skill at many schools where the workload is immense. So it could be worth your while to figure out what you’ve learned about your D’S strengths and preparation as you look at schools.
From there, you can assess what kind of schools would be best for how your D learns. Maybe it’s not a school with expectations that every student, including fast processing ones, will spend 4 hours a day on homework. Maybe a school with a wider range of learners would be good. Or one with a schedule that has kids taking only 4 classes each day. Or one that’s more hands on. Etc.
Put differently, depending on what you’re learned through SSAT testing and perhaps some math struggles, this could have been the best thing that could have happened at this point. You’ve got a little more information and can choose a school where she’ll thrive. There are lots of excellent BS, and you just need to pick ones that will be a good home for your D.
