@DrPrimo, we all have different experiences and different kids. One of mine got into a “top school” after dropping a course listed as required for the university, in order to take music theory. The theory class enhanced music outside of school, and the college seemed to care more about that commitment than the list of required classes. I believe the GC also wrote a note. But the OP’s situation may be very different.
As an aside, it can be tough doing music at the college level, whether BA or BM program, with a bunch of kids who have done conservatory prep or even who have done theory in high school.
