Should I send ACT or SAT scores to Yale?

Colleges and Universities A-Z Yale University

SAT:
1520 (800 M, 720 R, 19/24 Essay)
1530 (790 M, 740 R, 17/24 Essay)

ACT:
32 (33 M, 30 S, 32 E, 31 R, 10 Writing)
35 (35 M, 36 S, 34 E, 33 R, 10 Writing)

I also just want to confirm that we have to send either all scores from SAT or all scores from ACT, right?
Thanks in advance!

Look at the concordance tables and see which scores are better.

Re: sending all scores, yes, but “all scores” from SAT or ACT does not apply to SAT Subject Tests, each of which you can send or not send, regardless of whether you sent all SAT or all ACT tests.
