Undergraduate Online Registration

Online registration for matriculated undergraduate students.

After you log in to CLASS, click on My Registration to begin.

Follow these steps for a successful registration:


Open Planning

Open planning begins approximately three to four weeks before registration begins. In consultation with your adviser, you’ll select the courses appropriate for your major, indicate the special grading option available (normal, pass/fail, audit), and even select alternates (in case a course you’ve selected isn’t available). Check back before your registration appointment to make sure your adviser has reviewed your registration. You will not be permitted to register without this approval.


Once you receive your adviser’s approval, you will login at your appointed time (or anytime thereafter) and submit your registration to the system. Be sure to click SUBMIT to complete your registration. You’ll immediately be able to see your course confirmation listing your courses and their location.

Note: Classroom assignments periodically change, so please look at your confirmation again, right before classes begin.
