I take NO responsibility whatsoever for anything that happens to you for anything you do from reading this guide.
This guide will teach you how to get into, and exploit your school computer system.
First, turn on a computer in your school, in a quiet spot. When the login screen comes up, unplug the DSL(Large phone cord looking cord) cord. Then, login. It should give you a message saying something about not being able to connect. All you do is press OK, or whatever is there. You should now notice that all things usually disabled are now enabled. You can now open a command prompt, and add admin account? That sounds good

If you still cant open the command prompt, open up NotePad, type in "command.com", no quotes, and name it "command.bat", again, no quotes. Save it and open it, and you should see the command prompt. You can now do mostly anything, being you have control of the command prompt. I think you can delete drives by typing "delete D

.*", or whichever drive name you want to delete. Someone correct me if I'm wrong. If you want, you can try other command prompt commands you know.
If anyone sees any errors in here, tell me and I'll fix them.
