Hey, academics wise, your scores are top notch and good enough for admission at all of the schools you mentioned. Because you are applying for Comp Sci, aim for high 700s-800 in your SAT subject tests and that will further solidify you as a solid applicant. As for your extracurriculars, they seem to be pretty good, but make sure that your essays to those schools position you as unique and why that school’s Comp Sci program is good for you. It doesn’t help being in the Asian boat ( 
im in it too).
