If I take the ACT and cancel my results, do I still have to submit the score to Yale University?

If I take the ACT in December and then cancel my result (so I would simply be taking the ACT for practice under test conditions), would I still have to submit this test result on my Yale application?

I know that Yale wants you to send in every result you get in standardised tests… Does that include cancelled results? I would take the ACT for real in June.

Yale does not want you to send in every result you get in standardized tests, but if you’re sending in an ACT result, they would want you to send in every ACT result.

Since the score isn’t really canceled, in my view you would need to report it.
