Graduation Part 2

Ok, so I found out a while ago I graduate December 6th, and I talked to my advisor and I have everything all set, first good news I've heard from MCC. But I'm looking at my class schedule and it shows I have class December 11th, wait I graduate December 6th....does anyone else find something wrong with this? I was thinking of just not going to class what were they going to say I graduate the week before they can't make me come back.....I have a 30 min presentation to make that day.....Have I mentioned I love MCC?
