For most majors you will need a minimum of 120 credits to graduate. Both meet a total of 150 minutes of class per week. If you want your courses to be spread out evenly each day, you should sign up for three MWF courses and two TR courses.
Classes offered in the evening typically meet once a week for two and one half hours.
Remember, you may need to make adjustments in your personal schedule to fit into the course sequence of your interest area. Make sure to allow time for either lunch or snacks. During early registration students register according to their class standing, i.e., seniors during the first week, juniors during the second week, etc.
