How to remove an Coaliton application part 1?

I was procrastinating in what college I should choose, I applied a partial app to amherst.

I mailed the admissions team, no territory person assigned to me, there is no reply yet.

I took the november sat and got my results it was 1430. I thought it is not good to add it because it low but now looking at my 9th grade marks again. I think it is important to add it.
