Help!!! please

Hello everyone my mac is imaged by my school and i want to reset the computer back to factory settings but if i do it i will be suspended so i was wondering if would be possible for someone to hack my computer and reset it for me.

I don't have admin rights and the computer has a firmware password.
I can give you access via my account and you can do whatever it take as long as my hardware is not destroyed.

Its locked so i cant boot from CD in case you were wondering

wrong section and welcome

i know its the wrong section but please someone help me
