Full of idiots much like the rest of the world. You have the jocks and the popular crowd, which no one outside of them give a shit about. Try to steer clear of the morons, choose your friends wisely and if you believe something is being done wrong, say so...teachers and staff aren't always right and as long as you present a valid argument it should work in your favor! Other than that, try to keep up on homework and projects. Don't leave anything til the last minute, get it done asap.
In reality tough, you can learn a lot more just surfin' the web and watching history/discovery channels etc.
