I am sure you have not forgotten that this coming weekend is Labor Day weekend, so Monday is a holiday. What you may have forgotten is that Tuesday, September 8 is the Last Day to Add a Class. If you are dropping a class, Tuesday is also the last day to drop a class with an 85% refund. So, although you may have a long weekend of fun ahead, please remember that Tuesday is very important. The Registrar's Office opens at 9:00am and closes at 6:00pm.
Just so you know about another important date, here it is:
September 14 - last day to drop a class without a "W" on your transcripts (also the last day for 70% of your refund)
Have a great weekend!
