It's really quite bland. You show up at a set time, sit in rows of desks and listen to the teacher talk for a while then fill out a worksheet or two, maybe have a class discussion. The bell rings; you get up and walk to your next class. Repeat for however many classes you have, then go home.
Though, it's more of a game of how many people can you get to like you in every class. Girls are bonus points, and if you forget 'em there's a multiplier based on how attractive they are.
