Are you trying to edit Wikipaedia or just read it?
If you just want to read Wikipaedia, you could try Tor. Tor is an anonymising proxy network, and with each connection you get a series of three nodes. While most of these nodes are published, and hence easily blockable by your school, there are special nodes called bridges which are not published which you can use as entry to the Tor network. So, if your school is blocking the nodes in the Tor directory, you could configure Tor to use bridges.
Tor has to be installed, I don't know if that's a problem. There are bootable LiveCDs with Tor on them, though.
Note that you probably won't be able to edit Wikipaedia via Tor, as Wikipaedia blocks most of Tor from editing. Tor is good at evading entry blocks, as explained above, but makes no attempt to evade exit blocks.
You can find out more about Tor here: https://tor.eff.org
This problem is solvable - Wikipaedia could commit a patch for nym, which would allow you to get a cryptographic certificate from home, using your real IP, and then carry that cryptographic certificate to school and use that to identify yourself to Wikipaedia. However, Wikipaedia is unlikely to commit the necessary patch.

my school blocks at the least 95% of all proxies. I try and browse through wikipedia and it tells me that it is wikipedia is using a proxy server known as http://privacywant.info. Is this something that has happened to anyone else before, or is it just particular on mine.
thanks
