<p>If you retake your SAT I you should be fine for all of the UCs. UCs are numbers-based. They don’t really take into account your ECs. Harvey Mudd is probably a reach, but definitely possible if you can bring up your SAT 100 pts or so (especially the math). I don’t know much about Cal Poly, but I think it would probably be a match for you… UCSB has an excellent Chem E program.</p>
