Chance Me/Give Me Advice

Alright so I finished most of my interviews at the schools and I think all of them except 1 school were amazing, because the interviewers all either asked me to contact them with resumes, have a 2nd interview with them over zoom, asked me to contact the coaches because apparently my times are good enough, etc.

But they said the same thing. My math teacher refuses to give me a LOR because she believes its only for “college admissions” so they told me to ask my physics + 8th grade math teacher. Is that fine?

Also how much help does contacting the music directors + swim coaches help? The major thing for music is that I’m in a orchestra that tours in Europe, Asia, Africa, etc all paid for by sponsors and some other stuff. Swimming IMO isn’t the best but I made varsity team A and states so idk.

Thanks!
