You're wise to be asking this question before you get a glider.
The reality is that relatively few gliders end up living out their lives in the same home and with the same owners. While it's difficult to gauge, my guess is that most end up in 3-4 or more homes, and many end up as rescues (we're currently doing a long-term survey at www.sugargliders.org to see if we can track how many homes gliders end up having, and how often they are given up).
That's the reality. There are very few homes that I think are really right for glider ownership. Students cannot usually provide the kind of long-term commitment that gliders need. Life is too unsettled for most students. Work, social life, graduation, new jobs, new roommates, changes in living situation -- all of these can mean the relationship with your gliders suffer.
They are wonderful pets, but only if you have the mindset that when you take on gliders, you're making a lifestyle choice, and consider that YOUR life will have to adapt to THEIR needs for many years (healthy gliders can live a decade or longer) -- and not vice versa.
Here are some things you'll need to adapt to:
a) nightime hours and daily out of cage play time
b) bonding time, if you want the most of the relationship with your glider, that happens during the day
c) living quarters large enough for a large, usually not very attractive cage
d) changes in the way you live -- for instance, your toilet seat must always, always be closed
e) commitment to providing food every evening - involves chopping fruits and vegetables and fussing over them
f) commitment to sometimes expensive veterinary care -- while I wouldn't call their care fragile, it is exacting and problems do arise.
