i didnt do much tinkering on the pc's at the school's i attended although i did format the hdd on one of the pc's in the special need's unit and to this day nobody knows it was me i kinda felt bad but i was young back then.
in my 2nd school me and this kid were always in the library on the times we had free periods and the system administrator always kept telling us to try and hack into the school network because he knew damn well because of the little knowledge we had we wouldnt get through past the login screen we could only use our usernames/passwords and we didnt know the admin password not matter how we tried nothing worked.
