It depends on the school/program but mostly YOUR schedule. I am a sophomore BSN student who (as of this semester) does not have a full-time job. I am, however, a wife, mother, Nana and I have friends and other obligations. I use my free-time to spend with my family or do something for myself. You have to get away from the studying...even if it's for one hour or 10 minutes. If you don't you will burn out...very, very quickly!
Organize your time so you can use it wisely! For example, at the beginning of each semester, I write down my school schedule and the time that I will need to study for each class, clinicals, travel time, etc...write down everything you have to do for school. Then pencil things in your have to do for life, i.e., cleaning, laundry, work, etc. After that, I pencil time in to spend with my family and friends. If you have a good support system, they will understand your time is valuable and not very flexible.
Above all, if you want to be a nurse, really, really be a nurse, you will make sacrifices. But don't make too many to where you'll get burnt out and not have any sanity.
