I'm a senior applying to MIT, Stanford, Caltech, and maybe Princeton. I'm taking the Math Level 2 and Chemistry subject tests tomorrow. I just took two practice math 2 tests and got a 730 then a 760. Assuming that's close to how I score tomorrow, how much does that hurt my application? I know lots of admits get an 800. I want to do aerospace engineering. My ACT composite is a 35 with a 36 on math and I'm a National Merit Semifinalist. I got a 5 on the Calc BC exam but a 4 on Chem and will have a 5.0 weighted GPA, likely 4.0 unweighted. So, I have pretty good scores, but I'm worried about these subject tests. How big of a factor are they in admissions to elite schools?
