Can a Proxy Be Banned in School? How Do Schools Block Access to Proxy Sites?

Thanks for all the replies, guys! I tried a couple of the suggestions, like Tor Browser and UltraSurf, but they got blocked pretty fast. It’s crazy how quick schools are at catching this stuff.

I’m thinking of trying a VPN next, but I’m not sure if it’s worth the effort. Has anyone had any luck with VPNs lately? Or is it just a lost cause at this point? Let me know!
