My parents want me to go to a private catholic school, and I don't want to!?

Hi, I go to Public School 29 in Staten Island. The end of my final year is approaching and my parents have considered to take me to St. Rita's Catholic school. I've been going there for CCD and church, but I can't stand the uniform (plaid skirt and sweater vests) and how the teachers will be like, God is great, because he created the world and do your math problems! I've already been accepted and the cost will be five grand every year. My parents have a high income but we are like in the economy slump. The reason I don't want to go is because most of my friends are going to I.S.27 which is like the zone school. It's not bad, but in a bad neighborhood, but I'd be fine. Another reason was that me and my close friend Danielle were going to go, but a boy in her would-be class seems to be pulling down his pants and exposing himself to girls. I've already tried consoling my parents but it doesn't work out. I've also told my class that I might be going to I.S.27, so I could learn how to get in there. Please, if you are reading this respond. I need a lot of help.
