Here is a copy of the fall 2018 registration calendar—please see the highlighted sections to determine the census date. For fall 16-week classes, the census date is September 12th.
Keep in mind that dropped classes after this date will count towards your 6 drops you’re allotted for your undergraduate career. Drops made before this time will not count against you. However, if you’re using financial aid to pay for classes, you will want to contact that office to determine how much money you may owe back for dropping the class prior to making that drop. If you’re not receiving aid, you will want to contact the business office to see what percent of the cost of the class you’ll receive back.
