How to become an admin on my school computers?

Ok i have tried multiple ways of doing this and none have worked like going from basic>power>admin user or trying to add my account to the admin group. And all of these failures revolve around the simple fact of i dont have sufficiant permissions. (they even have a pword on the BIOS at school and i cant remove it trust me ive tried so i cant boot up linux live CD) and yes i know that i can get in big trouble for doing it if i get caught but i really dont care its the end of the year and i wanna be able to do something fun before the year is out. ive already got past the school firewall by using a proxy. So basicly anything that you need permissions for might not work at my school cause the school security program is a fcking nazi. also i made my own bat file for command prompt and have a 8GB flash drive if either of those would help. Ty for any help.
