Personally, what iI feel is that whether the course is required or not really doesn't matter. All that Mattersmatters is how much challenging is the student environment is. If you ever feel anytime that they have understood the concepts of Groupsgroups, rings, and fields clearly, then the next option is Galois theory.
As iI said before, it boils down to one thing: How muchhow inquisitive is the studentstudents are in learning the subject.
