How to bypass my schools's Lightspeed filter?

So I have a computer class where I have a ton of free time and I would like to play games and minecraft, but: I'm using a password that can run all programs, but not access internet, then I go to a blocked website and click not you and log in with my username and password, the password account that can run programs as administrator can't access websites. Also:

1) Minecraft doesn't play as the launcher is blue Xed
2) No proxy website works, nor does tor
3)I can't change the Wi-Fi
4) I tried removing the privaxcy policy however some of the files are completely unaccessible
5) WinRAR doesn't work
6) Proxy programs don't work either
7)Tor doesn't work
8) Tinyurl doesn't work
9) HTTPS doesn't work
10) I can open cmd but the commands always fail

I have tried every possible thing i know about

So I need to know how to get an admin account or bypass the websites. As of now i'm sometimes using google translate by translating a link french to english and it hardly works. Also if it is important the account i use to log into the computer, not internet USED to have full access before the school realized it. What can i do?

Added (1). Also many blocked websites are blue with a lighter X over it, and on the half admin account the websites most always say err_connection_reset. VERY FEW have a blue screen

Added (2). ALSO I can't copy some urls that are too long due to the lightspeed immediately redirecting and the link doesn't appear on google

Added (3). TO BE CLEAR i need to pass through lightspeed AND group privacy policy

You are aware that even what you've done so far is against school's usage of technology, correct? I knew someone in school who did exactly what you're trying to do - and guess what? They were barred from graduation and expelled.

There's no reason you need to be playing games in class. Draw, write, work on other assignments, talk to friends. Just because you have a computer in front of you does not entitle you to play games when you get bored.
