I guess it's better to think of it as more of a test of your endurance than anything. If your classmates are acting like children, remember that you're aiming to become a teacher. I bet you hands down that there will be at least one immature student within every class you end up teaching in the future, if not a class full of immature students. If you learn to tolerate and respect your uncouth classmates now, you'll be well suited for handling the difficult students you will most likely have in your future.
