“In the case of Subject Tests, there.is general guidance”
I specified what I was referring to, and it wasn’t Subject Tests. Do you disagree with the statement that there is no general guidance on SAT, ACT, and Subject Test combined requirements? Which is what OP asked:
“if I want to send my ACT score (it’s better than my SAT score) and my SAT subject test scores, do I have to send my regular SAT score too? ”
I also wouldn’t call over 100 schools “very few”.
