That's a no to both of those questions.
I rarely go to bed before midnight on most nights, even pre clinical days when I need to be up at 5-530am(depending on the commute..might be 4am sometimes!). I may be studying or relaxing, or just cant sleep(I take meds that keep me up at night at times).....HOWEVER, on the weekends, my husband and I trade off catching up on sleep...So on Saturday I sleep late(generally till about 10am) and Sunday he sleeps in. It doesn't always work if we have things to do though.
We have 4 kids, so not possible to both catch up on sleep at the same time
As for the schedule, I know many can pick their own schedule, and I guess you can in our program as well, but not your nursing curriculum schedule. You can pick your external classes such as psych, English, Math, etc, but we only have two classes admitted per year(one in the Fall, one in the Spring).
