I would say you need to finish strong this year and take SAT a few more times. They superscore so they take the best of each section from multiple sections. So if you got a 600 verbal / 680 math on your 1280 score. If you get a 640 verbal and 620 math next time it really counts as a 1320 (640+680). If you can get your best math score up to 700+ that will help.
From this year it appears they favor GPA over SAT though…so getting that GPA up into that 3.8 UW range (and also sounds like your school doesn’t go crazy with weighting … your taking their hardest classes).
A lot of good extra curricular too. And being Hispanic should help as well. I think you have a good shot.
