I think most students move to uni, but there are obviously plenty who don't.
As for whether or not you should, that is down to you and your priorities. But to answer a few question.
In terms of attending classes, pretty much the same as everyone else at university. You turn up to classes and labs (if you have them) as scheduled. Only differences I can think of is
1) you have to get the bus in (though even some students who live at their uni city have to do this, I have to get the bus in)
2) Less likely to walk to class with people for the first class of the day. I knew people who lived with their course mates so they'd wake each other up in the morning and go to class together. This isn't much of an option if you live at home.

Do you only turn up for lectures or can you do that and stay for the day to study (or something)
Of course you can stay for the day to study, some people definitely do this. However you need to bare in mind that sometimes you simply may not want to stay to study, you may be tired or hungry and end up spending a bunch of money on convenience food (I know I do when I go the library) if you don't pack enough for the day. You also need to consider class schedules. You may find yourself having a 9am class and then have to wait around until 3pm for your next class. Now obviously you could get the bus home, but if this is happening frequently or if you have several of these a day (class at 9, then one at 1 and your last at 4) you may find yourself spending way more money than anticipated on bus fare (unless you can get a bus pass that saves you money).Fact is you won't always want to stick around and study every day. Most people I find go back to their student halls or housing in between classes if the break is 2 hours or more, so you have to make more of an effort to get involved with people if you don't have people waiting for you at home to make friends with.
I'm not a stay at home student but I know a fair few.
