My Ipad Is Disabled

My Ipad is disabled and wont connect to Itunes because it says I need to enter my passcode. I don't want to reset it because I use for school and don't have the files on it backed up. Please help, I need my Ipad for a very important presentation on Monday!!! And yes I have followed the steps listed here http://support.apple.com/kb/ht1212 about 3-5 times abd it still doesnt work.
