How do I make my mom take me out of a crap school?

My mom thinks this school is gr8. I only went there because I thought they had sed they have “gr8 sports facilities”. Some teachers try 2 brainwash u (except 4 a few people most of the class is brainwashed) into thinking that music is bad (fuck her) and that “we should cover up in front of men”. Btw I live in pakistan…awful place. Its a muslim majority country. But muslims rnt supposed 2 whistle at girls or have terrorists in the country who bomb us and have clashes with the army. Its a fucking hellhole. And e way our principal made the leaflet thing bout the school. When I went to talk to her and asked her why it was incorrect she sed what do you mean. So I sed that the leaflet sed that there was extracurricular for evryone. I was really polite. But she called the middle school principal and I nearly got suspended. My mom sed that its the best school in lahore and people are dying to get in it so I sed let them have it I dont wanna go to such a stupid school. We have exams which I have never taken before. I used 2 b a straight a student but im not happy here n im gettin bad grades. My mom doesnt understand and I hate her for it. When I ask her to get me out she starts yelling and she hits me and stuff. I dont care. Teachers have favourites and stuff. Once my friend wore this totally hot strapless minidress and all the girls started saying : Oh, sara your not a real muslim. You luk so stupid in that. You get what I mean? These girls then went to a teacher who hated sara and asked her if that dress was against islam, right? She nodded and started lecturing sara. Sara told her mom who complained but was told that she could just take her daughter out of school. Our school isnt a registered religious school but they still teach islamiyat (about islam) in a way that makes the people in our books who were against the religion luk bad. My friend rachel is kinda half muslim because her mom is muslim but her dads christian. So our islamiyat teacher sed: Oh your a muslim? I wouldnt have guessed it.

Rachel has white skin so she sorta stands out sumtimes. Me and sara and ushna (also a friend) started talking back to the teacher and telling her she had no right to say that and that she was a bloody racist and it was people like her who made the world a bad place. We got sent to the principals office and we were suspended. I didnt care. I did the right thing. So guys, can you help me? Pleaseee! I need to convince my mom!
