SAT : Don’t remember exactly but its somewhere in the neighborhood of 1380. Can I retake it or take the ACT instead (?) (even though I’m 19) because I recognize that this is a really low score…Also my high school grades were just average-- how much attention will they pay to the test scores and high school grades?

I’m thinking of adding some more clubs to my list of extra-curricular activities too.

Again: what are my chances and how do I improve my chances of getting in? What will the admissions board think of me as an applicant?

Thanks!!
