Sooo... what's high school like for you? Or what was it like? And what can I expect?

It really isn't that exciting so I don't know what "hype" you're talking about. All it is is you're surrounded by older far more mature people (I'm not really talking about Freshmen here) and are in slightly more difficult classes. Your classes aren't very hard Freshmen year but get significantly harder Sophomore year. Have loads of fun..
