Expect a school full of kids who, honestly, spend too much time worrying over their public status. My best advice for you: don't care too much about it, ya'll do fine :)
actaully i made a friend on the very first day of school this year, in welding (i was trying to find someone from my MS and there was another dude right next to a guy from my ms, and i became friends with the dude that was right next to the dude from my ms)
last thing: prepare for your friends to not be in any of your classes and lunch periods. I have lunch with one of my friends but i dont have any classes with him tho. It's some experience from a current freshman.
