just dont go on the forums whilst you are in school
hope i answered your question
I'm not exactly sure about this but I heard kids at my friend's school were using TOR to get past blocks. It might work, and I think you can download its browser bundle for free.
don't use TOR unless you want to be murdered by the government
a lot of criminal sites are accessible through TOR.
my point exactlyif you do use tor try not to use google or anything like that just put in the website you want and stay on that site
