15 year old Sophomore being treated like a Child! ?

After summer break Imma be a sophomore at my highschool.. But my MOM being so strict won't let me go out or even go to the teen club... Now I got all a's on my report card fourth quarter nd she bought me a laptop... (I was wondering if I get all a's would she let me go out) But if I still can't go out nd I have the laptop.. I want an exchange.... Also she won't even let me have a boyfriend.. Even doe I have them anyways behind her back.. But how can I tell her... In a nice way.. That im a good girl in her eyes ;) nd that I should grow up nd hang out.. More
