Should I send 2 SAT Subject scores?

I have SAT Biology M - 780, but my Math Level 2 result is horrible - 610. I have no chance to retake. Can I send only my Biology results to that universities which recommend to take 2?

Yes. Someone will say no. But why not send that one good score.

Edited to say that question in subject line is the opposite of question in text.

I would send the one good score.

You certainly can send only one - should you is the real question.

I’d say it’s probably a wash. The score obviously won’t help, but not sending it won’t meet their recommendation and, as almost no one only takes one Subject Test, especially not taking math, they’ll likely assume (correctly) what happened.

I would send the biology score

To clarify - I responded to the question in your title, should you send two scores, not the question in your text, should you send one score.

You should certainly send the Bio score. Sending the Math score in addition is a wash.
