Adding an Undergraduate Music Degree - STEM kid?

I’ve never had a private voice teacher (or voice lessons) as I stated in my first post. If I did, I’d be primarily asking them. I will talk with my choir director on Tuesday. If I decide to go for an auditioned degree program, I’ll take around 8 lessons with her, for preparation. Otherwise, I will take lessons with her on the side (and forego the music degree). The total amount I have saved for lessons so far is $240 and she does give lessons.

I know it’s worth it, but for the next 2 months I have neither the time nor the additional funds for lessons or practice - I’m taking 15 credit hours, 12 of which are challenging, and other ECs require my time.
