I'm thirteen (fourteen in six days) and some of my classmates deserve a smack upside the head. Here is what they do:
~ laughing ALL the time (it gets so annoying)
~ yelling stuff in other languages
~ screaming
~ starting stupid fights in class (they always end up hurtling into MY desk, too. -_-)
~ if you're sharing a desk, they sprawl out their elbows so you don't have enough space to write
~ making weird noises
~ challenging to fight anyone who dislikes football (or soccer, if you're from the U.S.)
~ challenging the teacher
~ flicking rubber bands all over the place
~ talking when the teacher tells them not to
When does this end? It's so irritating.

That was probably one of the worst years at secondary school for me, too... And for pretty much the exact same reasons! People always mucked about, shouted, swore, argued with the teacher, walked out of lessons, had arguments with each other, threw stuff around... I think once in history one boy picked up all the textbooks and hid them on top of the cupboard so we all had to stay behind after school because of that. It feels like they only seem to do that because they're one of the older ones now so it boosts their ego and makes them think they're really cool when they're really the opposite... It was really irritating, and I was so unhappy because I was being bullied along with that too, and I really just didn't feel comfortable in that class of people. I found that going into year 10 and 11 was a bit nicer though because people start maturing a bit more then and they start to work harder because of exams and etc. You'll still get a few people who muck around, but generally it's a lot more calm. I'm sure that will happen with you, too! 
I've left school now since I've done all my GCSEs so thankfully I don't have to put up with my old annoying classmates anymore since I am transferring to another sixth form... but it DOES generally get better the higher up the school you go, so don't worry. 
Seriously, sometimes I wondered if we were still in elementary school. Probably what bothered me the most was the outright disrespect towards everyone, and the overwhelming sense of entitlement. I am so tired of hearing "the teacher failed me because she doesn't like me." Anyways, I could rant and rave for ages about it. Just like me though, I am sure things will get better and it also helps to surround yourself with people who are similar. That's what I did, because then I didn't have to deal with my other classmates. When it comes to being in the more challenging classes, all of those students act like they are so much better than everyone else. I was in a ton of Advanced Placement and Honors classes, and I am honestly not sure which was worse between these and the regular classes. They are usually less obnoxious, but more snobby I suppose.
I would also hear these two boys next to me talk about inappropriate things, and yes, I tried so hard not to listen. Yeah, I'm glad I won't see them next year.
Teachers never even said anything about it to them and it was just horrible xD
