Seriously man! I know how you feel..luckily my school is pretty big there's alot of other things to keep busy with -- there's a game room with pool tables, ping pong, video games (PS3/XBOX 360, etc) so yeah lol I don't have time to spare in school really
Get friends to hang out with. Seriously, I think it's better to keep up social skills than smacking up any consoles. Though pool and ping pong, that's a great way to chill. In my school we use to chill at the student lounge, relaxing, killing time and talking what ever comes in a mind. And if there is more than half an hour, I've used to go lifting weights. And sure, sometimes surfing the web with my laptop. But never got bored sitting alone to wait next lecture. But hey! Everybody makes the way they prefer Get social networked!
Hang out with your friends in the canteen, listen to music or better still if you play some sport like basketball or something, go sweat it out!!
Judging from my google stats type pervy things into Google and for some strange reason still end up on one my Automotive sites....
Find a great book and bury your nose in it. Or you could find a great friend and bury your nose in him/her. Haha!
