I go to a large co-education, Catholic, private school that goes all the way through like yours does. My school is strict, no make-up, unnatural hair colours, nail polish, the control how long our skirts are by the centimetre, every aspect is controlled. The teachers are all hypocritical and two-faced, they say one thing then do the other. The teachers don't care if you get hit by a bus just as long as we're wearing the uniform right.
It's crap and over 3 quarters of the kids at school hate it and wish they could go somewhere else because the teachers don't give a **** about us just what money they're getting through the school fees which is more than what it's worth. My school is only worth a quarter of what you pay.
