Help! What to submit?

I have a conundrum with what scores to send to what schools! Please help!
Many of the schools I am applying to highly recommend sending 2 subject tests. I’ve taken 2 total, with the break down being: Math 2- 790 Literature- 650. That literature is rough, but it doesn’t properly reflect my ability in Lit- I received a 5 on AP Lang. Should I just send the math 2? or both? or neither?
Additionally, for the schools that say subject tests are “optional” should I submit just the Math score, both, or neither?
I am worried that sending just one may look suspicious.

bump.
