Berklee schedules are pretty nice because the earliest class is at 9:00am and the latest ones I believe are 6:00-8:00 but that is very rare. There are Friday classes of course, but you can make your own schedule so avoid them if you wish. The practice rooms and studios are used when school isn't in session and can be reserved. The studios are literally used all hours of the night, every night.

A full time schedule would have you taking around 8 different courses each semester. This will include private lessons, your general eds, harmonies, ear trainings,electives, and usually one ensemble and two labs at a time - but again you can choose exactly how you want to go about it.

It can be a heavy load depending on how much work each class requires but its very doable.
