Its probably blocked by a tight firewall, with the right IP address and things of that nature if could be broken, but from a friend of a friend who did this and suceeded...but then was expelled its not worth it!
bypass the schools filters by using a proxy or something a really good one are proxyring.com or if you can get to the internet options i have another way but just try using that for now
You could try a proxy site. They're made to allow people to get through firewalls and go on 'forbidden' sites at work or at school. Try googling 'proxy sites' or something.
You will have to bypass the security by using a proxy.
bypassing (AKA HACKING) security measures will be grounds for expulsion. Expelled=KICKED OUT FOR GOOD.
