No, the Honors College is designed to be flexible and fun so that you may achieve your academic and professional goals. Honors courses aren't designed to be harder or more work. They incorporate interactive learning methods that engage you with course material in unique ways.
Honors courses may also satisfy degree requirements for your major, general education requirements, and general electives. You aren't taking more courses, but taking honors courses that fulfill multiple requirements.
Membership in the Honors College is different from membership in national honor societies. Membership in national honor societies is open to eligible honors and non-honors students through invitation. Honor societies can be a valuable resource for building a professional network.
