For schools that require one test score, do I put both SAT and ACT?

Hello,
I have a small question, I got a 36 on the ACT and a 1560 on the SAT - I obviously will report my ACT score, but I am wondering whether or not to also report my SAT score? It seems that the percentiles for 36 on ACT and 1560 on SAT are the same, and I was thinking would reporting both scores show that my 36 was not a fluke? I ask this because my GPA is lower than you would expect someone with a 36 on the ACT to have.

Thanks!

Since it shows consistent performance across test types, I would report both as long as you’re willing (or your parents are willing) to pay for both score reports where needed,

A 36 will not be seen as a fluke. That would require it being a fluke across all the test areas. Send whichever or both. Work on some other part of your application now.
