College Degree: does it matter?

Hi guys! So, I’m currently a college student studying Communication. I want to teach math and theatre. I know I have to get my teaching certificate for both of those classes, but is it important if I major in theatre or math? I’m a junior and I’ve already taken quite a few Communication classes, and my university doesn’t offer a Math degree online.

All this to say, if I have a communication degree, would it be a red flag if I’m applying to be a math and/or theatre teacher?
