Should I send my scores?

I just to the SAT Subject Tests in Chemistry, Spanish with Listening, and Math 2. I did alright in math, alright in Spanish, and really bad on Chemistry. That’s just how I feel about the tests, I don’t know my actual scores yet. The schools I’m applying to don’t let you choose to send scores differently. For most of the schools, SAT subjects are optional, but some require it. Should I send my scores even though I have a bad feeling about them? Since Chemistry was hard and I think I’ll do better in Physics, I’m taking SAT physics and Math 2 in December. Since I’m taking these tests in December, should I just not send my scores? Thanks a lot in advance.

What percentile would your scores place you in?
