It depends on the day, the school, and the person.
My schedule generally looks like this:
7am: Wake up, get ready, breakfast
8am - 12pm: Lectures
12pm - 1pm: Lunch, Chill
1pm - 5pm: Study/Review material
5pm - 7pm: Dinner, chill
7pm-12pm: Study/Review material
However, some 1-3 times a week, I will have lectures from 1pm-4 or 5pm as well.
I generally spend so much time studying because I have a really hard time getting myself to focus, so a lot of that study time goes to procrastinating. If I could become more productive, I would probably get more free time at night.
