I'm not sure if I want to move schools?

Ok, so in September I started high school.

I do well in school but lately I found that I'm nowhere near my art ELoP (expected Level of Progress) for the end of the year. I'm meant to be a 6B because it's based on maths and english levels. I'm pretty good at art too but in the last assessment I dropped a few sub levels because I missed a lesson for a history trip (which only a few people in my form went on). Today earlier my hair was falling out of the bun so I tried to put it back right but couldn't because I needed a mirror The hair began falling in my face and began to annoy me. It was only for a few minutes and I just put it in a ponytail in the end but my teacher accused me off 'messing with my hair for all the lesson' Accusations like this happen to a lot of people for no reason (and I did finish my work at the time too) My dad says having different hairstyles is getting in the way of my studies- but they're not! There's about 3 people in my form the head wants to throw out too. My parents think that all the bad behavior is going to effect me.

I have 2 geography teachers, the first one can't control the class and the second isn't qualified in geog, she's meant to be a supply so I'm not getting anywhere.

So my bro is really intelligent too but parents said that if he doesn't get at least As in all GCSEs I'm going to move to a grammar

Most of my friends go to the local comp and I want to move to there but my parents say it's a rubbish school, its not tht bad plz help!
