I had jaw surgery this summer and would not have said that studying or being at college at the same time would have been possible. Do you know whether you'd need single or double jaw surgery as recovery has very different rates!! I had double jaw surgery and was pretty much bed bound for the first week due to lack of energy from not being able to eat. Due to the swelling and dribbling, I didn't really leave the house in the first 3 weeks. Every individual is different but I'd say you can't expect to continue your life normally for at least two weeks. Hope this helps, message me if you need more information or advice!!
