I tried both TCP and UDP and changed ports a few times. I dont deleted the configuration files

Hi my school blocked a lot of VPNs and i dont know what to do. They blocked Hotspotshield etc. Also they blocked L2TP an PPTP VPNs. I bought StrongVPN today and that also didnt work. I also cannot change my DNS Servers. Tor works but i cant use java on it (if someone can tell me how to get java working on Tor my problem would be solved). Im on Mac BTW. Any solutions for this miserable problem? Im in a boarding school so I cant live without VPN. Please Help VPN Masters!! Ask me for additional information if needed thanks.
