To send or not to send?

Hey guys, I would like some advice on whether to send my mediocre subject test score to fairly selective schools (12-30% acceptance rate). I have a 660 USH, 690 M1, and 760 M2. I will definitely send my USH and M2 to schools that REQUIRE two subject tests, but I’m not sure what to do for schools that DON’T require them, but RECOMMEND it. In the case of selective, subject test-optional schools should I only send the M2? Any other thoughts?

If they say recommended it means send it unless you are low income and can’t afford it.

@“Erin’s Dad” Hey, I shouldn’t include M1 because the difficulty of M2 supercedes it, right?

If they recommend two then use two.

Don’t send your Math 1

Thanks so much everyone!
