My kid has a 4.0 UW and plenty of rigor, and great class rank, leadership, etc., however her SAT is only 96%ile. It is holding her back. Generally kids with a couple of B’s but SAT’s of 1480+ are doing better than her admissions and scholarship-wise. I don’t think a 1590 will make up for a 3.7 UW, which I would think is more than a couple of B’s.
I’ve also found that you won’t even be considered for any top scholarships unless you have an ACT of 34. Just our experience. I am sure there are exceptions, but we didn’t find them.
