High School and a new Era

So today was my first day of High School...yes I am a freshman...it went better than I have expected it to and I'm grateful for that, I was just wondering if anyone had any helpful tips on High School because honestly I'm still scared of it, my teachers are cool but I don't know about the kids there...so yeah if anyone could give me some helpful tips the would be greatly appreciate :D. and now a New Era for MCR this is absolutly amazing!!!! I really hope the record comes out soon and as much as I love Danger Days I hope this album goes back towards the Three Cheers and Bullets sound...what do you guys think??
Thanks for everything :)
