My shift is 3-11:30, which unfortunately for me is the busiest shift so I don't get to study except during my dinner break (which I sometimes miss if it's crazy). I take classes during the day - 4 days a week. I usually try to plan class no earlier than 9am, but next semester I had to take an 8am class 2 days a week.
The schedule for the nursing school at which I'm accepted is 9-3:00 so I will go right from there to work 3 days a week. Everything (including clinicals) occur during the day, Mon-Fri. I work every other weekend so I only work for 3-4 days at a time, then I get a day off; 2 days off in a row every other weekend.
It's a tight schedule - next semester will be tough with A&P II plus micro (2 lab classes = yuck) but I need to stay full-time for the benefits and higher tuition reimbursement rate.
I have all my PTO time saved up and I use that as I need to for school (studying, etc).
I wouldn't trade the experience I'm getting for the world, though.
