<p>So for Northwestern and Columbia I can choose to JUST send my ACT score (35), instead of subject tests and SAT. I got 720 math and 650 chem. All my other scores/GPA/class rank/ECs are excellent, but I was really sick when I took these subject tests (hence the bad scores) and can't retake them at this point.
I was thinking of maybe just sending the math....?</p>
<p>You should check the website, but I think Columbia wants all the tests you have taken.</p>
