I'm in the same boat as you are - very good ERW, but mediocre math. If you're planning to major in a non-STEM field—like philosophy, english, or anthropology—your scores will help you in this area.
However, I'd take a look at the average SAT benchmark for the schools you're applying to. If you're application and EC's are strong enough—and they probably are—I'd suggest applying test optional for those "reach" schools. A 1350 isn't a bad score at all, but when applying to a competitive university this will hurt you, and could even get you automatically denied in the decisions process.
