Are my SAT Subject Test scores good enough to send?

For early action, I’m applying to Boston College, Umich, and Uchicago. I was wondering if my subject test scores were good enough for these schools. Any help would be appreciated!

Biology M: 740
US History: 730
Chemistry: 730
Math 2: 760

I researched and NONE of the three schools I mentioned above require that I send ANY SAT subject test scores. I don’t know if these would help my application. I looked up percentile ranges and I think they’re all around the 60th percentile, which isn’t so hot. Some other people have told me that if I don’t send anything, they’ll assume I did badly or didn’t take the test, which is a bad sign, so it’s better to send. Just wanted some extra feedback.

Thanks in advance!

They’re all fine to send.
