However, you *might* choose to wear cords representing:
* Honor Societies: Many honor societies (like Phi Beta Kappa, Phi Kappa Phi, etc.) award cords to their members that are worn at graduation.
* Academic Departments/Schools: Some colleges give cords to graduating students in specific majors or colleges within the university.
* Military Service: Students who are veterans or in the Reserves or National Guard may be entitled to wear cords representing their branch of service.
* Extracurricular Activities: Occasionally, colleges will give cords to students who've made exceptional contributions to student government, specific clubs, or volunteer organizations, although this is less common than the other categories.
In short, the necessary cords are none, but the *optional* cords depend entirely on your accomplishments and affiliations during your college career. Check with your college's graduation information or your specific organizations to see if you qualify for any cords.
