I went to public most of the time, it was just bad most of the time
I went to private college (french collège) and i had a great time, at the end they couldn't kept me but i had two very good friends there and as they never had young people like us they didn't know what to do

:P It took them a bit of time to find out what should calm us, in public they knew what to do in the next second

(three hours of maths on sat morning and if i wanted to escape, it was during a month as example

) so when they started to be strict in private too, i started to act badly again

and they said good bye
Honestly, i'm not traumatized by private - even if did a lot of things which were not allowed i worked well, my results were always good. And it's maybe the best years of school i had
