overlap means we use .intersection() or .issuperset()?

  1. "where the supplied set and the course's value (also a set) overlap." I feel overlap means at least one intersect, so intersection() should work right?
  2. My code runs correctly in my IDE, but runs into Bummer: Try again! here, can anyone help me identify my mistake? Thank you!
