Hey alanna,
I'm an architecture student, and before my jaw surgery i would be in studio working on projects 12hrs a day every day of the week.
I had my jaw surgery during the semester as well, I was given medical leave for 4 weeks, but I went back to class after one week.
Catching up WAS really hard, but I think if you do some work at home while you're recovering, it won't be that bad. After about the first couple of days you will probably get sick of lying around in bed and studying/reading will seem like heaven! :D
