Math requirement for Music Majors (Contemporary Vocal)

Looking for some guidance for my daughter entering Senior year on course selection. She goes to traditional high school in the morning and performing arts school in the afternoon. She’s taking private vocal and piano lessons as well but has only done those for 1 year. She’s got an 85 average so far, not sure what GPA that translates to.

She’s taken 3 years of Math so far (Algebra II, Geometry, and Pre-Calculus) and gotten high B’s on the first 2 but struggled a bit with a high C in Pre-Calc. Does she need to take a 4th year or can she use that slot to take Piano, or an Entrepreneurship or Computer Science course.

Right now her top schools are:

Berklee
University of Memphis
Loyola New Orleans
University of the Arts
University of Colorado Denver
The New School - Jazz and Contemporary
Cal Arts

Any guidance would be appreciated.

I would look at each individual schools requirements (usually on the website) and usually, but not always, a good performing arts school will have advisors.
