3.75 UW
Rank 45 in my class; top 8%
SAT score: 1350 (not sure if I should submit or not)
12 AP’s (mostly 3’s though)
My EC’s are decent.
Planning on applying to Department of Science ( CS major)
I would say my common app essay and supplementary is pretty good (many teachers have given their critiques and based on what they said they loved it)
Early Decision! Please let me know. 
A couple of tips - I would not submit that SAT score or the AP scores. The GPA is strong, and the course rigor with 12 AP courses taken is strong. The test scores only bring down your overall application as 1350 is below the 50% line for admitted students at BU. I think it is probably a bit of a reach, but definitely worth taking a shot at. You have an impressive overall profile and will definitely get in somewhere that will suit your talents. Good luck!
