Should I send SAT or ACT?

I’m applying to some fairly selective schools like UMich, Penn and UChicago and both my SAT and ACT scores are quite similar, so I was wondering which scores would be the better ones to send.

My ACT:
English: 35
Math: 34
Reading: 33
Science: 27
Writing: 35

My SAT:
Math: 740
CR: 720
WR: 710

bump

They’re virtually the same and both really good scores by the way : ) A 2170 is on very slightly better proportionally because it equals a 32.55 ACT and you got a 32.25 on your ACT but it really doesn’t matter which one you send because no one college is going to compare them proportionally like that.

I personally would send the ACT though because that writing score is very good.
