Decided to do a roll for your classes-... lol, you got a natural 20. You can do a roll for how well I did if you like
Despite not being entirely there, you find yourself drinking in both the lessons for that fourth day of class, and easily drinking in the stuff you'd missed. It was almost as if you somehow had been there and just had to recollect it all. Your classes go by smoothly despite those odd occurances, and soon its the afternoon. You know that I still have another two classes that each last half an hour, so you have about an hour to yourself.
You could start asking around, see if any of the senior students or faculty know of any interesting places off campus to go for some fun or a bite to eat, or you could relax... the next hour was entirely yours to do with it as you wished.
