Send 2 good/decent scores or send said scores + a not-so-good score?

Bio- 800
Chem- 740
Math II - 680

Am I better off just sending the bio and chem scores or should I send them all?

I would not send the Math 2 680 (47 percentile). Chem is 70 percentile. I don’t know any school that requires 3 anyway.
