Personally i'm hoping the clock will go slow enough to get involved with each lesson so then you have enough time to do your own thing at breaks and lunch.
I agree, i hope Bully's clock doesn't work like GTA's clock.
I mean, what can you do in 1 minute classes and 3 minute breaks, not much.
The 1 day = 24 minutes system worked well in GTA but in Bully you have a schedule to accomplish.
