Did you take the junior-year PSAT? With such a high SAT in an “uncompetitive” state, I’d think you would have a good shot at National Merit, or National AfAm Recognition at minimum…
I only have time for a brief response right now, but I’m wondering if you’ve considered the Claremont Consortium. Terrific CogSci and interdisciplinary potential, and the patchwork of 5 LAC’s that are fully adjacent and have a fully-integrated registration portal (plus shared EC’s) mitigates the “too small” problem, giving you the resources of a mid-sized university with around 7K undergrads altogether.
Another possible safety might be UT Dallas. Their CogSci department reminds me of UCSD’s, with the same tech bent and multiple tracks. If you actually got National Merit and neglected to mention it, the NMF package here is excellent. Cognitive Science BS - School of Behavioral and Brain Sciences | The University of Texas at Dallas
