Should I send one or the other? Or both?

I currently have a 2200 SAT (superscored) CR: 680 M: 760 W: 760 and a 33 ACT (single sitting) 34E 33M 33R 33S. Should I send both? Or just one of them based off the info above

They are both outstanding. Send both.

The superscore is roughly the same as the ACT per the comparison table on the ACT website: http://www.act.org/solutions/college-career-readiness/compare-act-sat/

However, not all universities will superscore, so you should only provide the SAT to places that superscore – I assume your SAT scores were significantly lower when looking at each test.

You should send in the ACT everywhere. That means you’ll be sending in both the ACT and SAT to places that superscore, and just the ACT elsewhere.

The universities I’m applying to all superscore @mommyrocks my superscore is based off 2 test dates, one had the highest writing score and the other had the highest math/CR. But the lower score wouldn’t be held against me between the two right?

The universities will use whatever it considers to be your highest score, whether the ACT or the superscore. Just send in both.
