Subject Tests sufficient for UVA?

Hello, I am hoping to apply to the University of Virginia within the next month. I wanted to ask if my SAT II scores were sufficient, even thoughI’ve been told that I shouldn’t worry, even though they aren’t they aren’t the best. I will note that my only two somewhat decent scores were both Math SAT II, and fit me better because I want to focus in a mathematics-based major. They are as follows:
Math 1: 720
Math 2: 640

However, I did test better than these scores on regular testing (SAT Math was a 780, while my ACT was a 32.) I’m just asking to potentially clear my worries.
If anyone needs more info from my profile to help, then I will be more than glad to provide info; I’m think that my profile is sufficient enough, but I’m not certain about that either. Thanks!

Subject tests are optional for admission. See https://admission.virginia.edu/admission/testing

Bump- Also, can anyone additionally tell me if I should retake Math 2 and/or take a different subject test as well? Thanks!
@neonpinklime Thanks for telling me! I was already aware that it was “recommended” for UVA, but I know that my sister didn’t take SAT 2’s when she applied, and she was denied.(And her application, like her SAT scores and EC’s, were a little stronger than mine. However, My ACT, GPA and awards are the same/better than hers.) I just want to supply as much as I can to bolster my application. Thank you, though!
