Quick Question

I just wanted to make sure I understood this correctly

So lets say I apply to a school that requires test scores from ALL test dates, if I send my ACT scores I don’t really have to send my SAT II scores (assuming I do really bad on Saturday) since they are from two different testing companies ? I plan on taking only the subject tests, not the full SAT.

Some colleges specifically require SAT Subject Tests; check each college’s website regarding testing requirements. Usually schools that are not test-optional will require either the SAT or ACT, possibly in addition to SAT Subject Tests.
