What is different about high school?

What is different about high school? I know about the classes and all that jazz, but I'm talking about they people. Do they really change? Any tips?

Most people mature over the summer before starting highschool. You should really stay on top of your homework and have really good study habits.

High school is full of drama to tell you the truth - its so much more different. A lot of people do definitely change because they are getting older and all that - you cant really expect anyone to stay the same. Your choice of friends will also most likely change, it tends to happen in high school. Just focus on your future and don't get involved with stupid things that people pressure you into because you will regret it.

sorry to tell you this but people change over the summer into highschool. I learnt it the hard way! :[ stay yourself! :]

all your best friends now ,
won't be in highschool
you wont even talk to most of the people you talk to now
you'll probably become a whole other person

the hard truth .
