What subject do you ‘wana’ apply to study?

ECs that are relevant to the subject that you hope to study can help to demonstrate your interest in, understanding of, and aptitude for that subject.

I have seen a student accepted with just 3 SAT subject tests- but he blew the aptitude test out of the water, and could not sit APs b/c he was competing (successfully) in international competitions in his subject. In general, there is a preference for APs over SAT subject tests.
