What Subject Test Scores Should I Send?

I took the May subject tests and got a 740 on Biology (85th percentile) and 780 on Math II (72nd percentile). I’m planning on applying to school such as UCLA, UC Berkeley, USC, Stanford, BU, Brown etc. If the school doesn’t require subject tests, would it be beneficial to submit one or both of what I have and if they do require, which would be the better score to send? I know math is higher score wise, but it is lower percentile wise, so I’m not sure if it’s better than my bio score.

Both are fine.
