I'm not sure why you would need hospital admissions before surgery, maybe a few appointments to do a pre-op physical and talk to your surgeon in detail about
the procedure. Your hospital may have a different protocol, so make sure you find out exactly what you need to do beforehand.
As for recovery, I was in the hospital for 6 days. When I came home I still needed help getting up from bed and sometimes the couch for a few days, but after that I was able to do everything on my own, although still with some back pain from the hard surgical table and not moving around for so long. The key is to walk as much as you can without wearing yourself out, you'll recover much faster than if you just sit on your butt all day. So I would say that 3-4 weeks after surgery I was ready to get back to life.
Also, what I've done in the past is I've taken my finals a week or two early so that I can get a little extra time. When I had UC I tried a lot of alternative treatments, and one of them involved going to the Czech Republic to drink mineral water. My mom booked the trip for a week that ended up being my finals week, so I just told all my teachers the situation and that it was for my health. They had no problem letting me take the finals early. Even an extra week would come in handy for your recovery. Also, if you talk to the teachers you're going to have after the break and tell them it's apossibility that you'll miss the first week of classes I'm sure they'll understand as well.
