Really depends, what week, the week before exams, is more intense, right after exam its more lax. Studying is always there hanging over your neck, but you simply make time for other stuff. The key I find is to not study equally, but pick and choose what you are gonna put more time on and what less, some material you just pick up eazier, or its simply less demanding, others you gotta spend more time on, if you do that, you should be able to have time for yourself.
I dont' really have a schedule perse, I study whenever I can and take a break whenever I want.
