Can I get into Cornell's business school?

In which program/school? In any case, your SAT is very low for Cornell, which at this point, gives you low chances. It’s possible your ethnicity could give you a boost. No one can tell you if you could get in or not, since we’re not in admissions. Retake your SAT (or ACT) and you might also need SAT 2s (not sure for your program). Good luck.
