Elective Courses

Hello,

I noticed on the Carnegie Mellon admissions site that the School of Computer Science requires 3 electives. There isn’t any elaboration on that, so I’d like clarifications for what that means:

  1. what is considered an elective? Are only non-required art courses considered electives, or are science/math based additional courses like research or computer science or AP statistics considered electives?
  2. I took band for three years and will take it again senior year: would that satisfy the requirement?

Thanks!
