<p>Score choice doesn’t apply to the subject tests. I called the admissions office when I applied (I was accepted ED) and they said that you don’t have to submit all of your subject tests if you don’t want to. Score Choice, which Cornell doesn’t have, only applies to the reasoning test.
You might want to consider sending the score in anyway - I was accepted with a 640 on the math section of the reasoning test, and they do like you to have two subject tests. It’s hard to say whether it will help you or hurt you more - I guess you’ll just have to make that decision.</p>
