*Jaw drops open* You go to a Montessori School?! That must be amazing! I'm homeschooled, but I know a lot about Montessori, they seem spectacular. But anywho... back to the point. My high school was tiny (when I went to public school) so I don't know how relevant of advice I can give. What I can and will say is be yourself, don't worry about mainstream activities, and trust me, you will find peeps like you. Many high schoolers in the big schools were previously homeschooled, from Montessori, private schools, etc. Plus you gotta think, no one is "one dimensional" - in other words, with only one personality. Everyone has different parts to them, so you are bound to find something in everyone of which you like. The same, if they are paying attention, towards you. 

So yeah, just be yourself, focus on getting great grades, and don't worry about what others think. Good luck, Dragonfruit! Also, if you mind my asking, what's it like being in a Montessori school? Did you like it a lot? 

My advice would just be to find someone that's willing to let you follow them around and ask a lot of questions, and let them be the channel for any things you need to know. 

Middle school isn't as hard as you think it is. Give yourself a goal every day, for example, don't get lost or learn someone's name.

See if you can visit your school before it starts and learn where your classrooms are. And even if you don't remember them all, don't worry! All the sixth graders (right? you're a sixth grader?) are going into a new school, and the teachers will help you.

Just don't worry and have fun! 

MONTESSORI BROOOOOOOOOOOOOOOOS!!!!!!!!!!!!! OMK, wow! I didn't know anyone else on here went to Montessori! Awesome!

Well, while it may be confusing at first, all of my friends who have already started high school seem totally happy and not freaked out by the change. I'm not sure what tips to give you, but I would just try to be confident and try not to feel stressed beforehand. I wouldn't worry about your grades because the Montessori system teaches you a lot and at a high level. All in all, just try to go into it with a good attitude, and see what happens! Good luck!

Oh, I have some tips!  Some of them may have already been said, but that's because I read none of the comments.

1. Have good time management.  I never really had amazing time management skills, but I really had to get my act together when I started seventh grade last year.  I had to find the time to pack my stuff (which always took forever) while paying attention and preparing for the sprint to the next class.  

2. Keep a planner handy.  At my school, they gave you a planner, but yours may (probably) won't.  If you're an disorganized person like me, get a planner so you can map out what assignments are due what days.

3.  Ask for help if you need it.  I didn't do this often, just because I don't like asking for help.  But if you need help, ask your friends!  Ask your teachers! 

Don't worry about fitting in. Don't worry about sticking out, either. I made about a hundred mistakes my first day of middle school, but I survived. Every first day of the school year is exciting and weird and sometimes overwhelming or even boring. There's always something new.

I went to public school for years, so a few guidelines; Obey the teachers (at least when they're looking), make sure you get to class on time (get a watch if you don't have one and the school doesn't have clocks everywhere), be prepared for classes (but don't drag around everything you might conceivably need for all of your classes all day), talk to the people you want to be friends with, and don't kill anyone if you can avoid it.

Don't play with your phone or any devices during class; that's always a surefire way to annoy the teachers. If you want to doodle in class, go ahead, but take notes too so you can prove you were still paying attention. Time management is important for homework; write down your homework and do it the day it's assigned if possible so that you don't forget anything and can get it done. Don't let it get in the way of sleep or eating, though; you need to be alive to learn. And preferably also conscious. 

All right, that's it for me. Hope this helps! 

Thanks, Lucy and Viola? That's really helpful. 

Also, @EG, I agree, everyone acts so mature and thoughtful, and you are all such good writers! 

From reading all the comments, it sounds like you have some great advice! All I have to say is if you need a friend, be a friend. Anyone would be lucky to be friends with you. Best wishes with your new school!

Oh, good luck Dragonfruit! I have quite a bit of experience changing schools - I'm currently at my sixth school, ninth including preschools! Hm, now that I think about it, I'm not all that good at it either, but I'll do my best to give you some tips :)

1. Try and get to know as many people as you can on the first day. You will probably end up sticking with these people for the rest of the year, so make sure you like them. But of course, you can always find a new group of friends if that one isn't working for you.

2. Don't worry about sticking out. Fitting in is boring, who wants to be like everyone else when you can be whoever you want to be? At my old school my friends were the weirdest group of people you could meet, and we were incredibly close and happy together. (Hehe but you might not want to be like us, I mean, we were really weird, like walking around making sheep noises weird XD). And as scary as it might seem to change to a new and completely different school, you'll always adjust to it eventually. Even if the first few days don't go so well, they can alway get better.

Anyways, I have to go, but first I have two somewhat unimportant questions:

1. Did you say you start in a few months?!?! I just finished my third week of school!

2. If you call middle school high school, what do you call high school?
