How do I bypass my school's internet which is blocking sites?

Use a 3G connection on your own phone, instead of using the school WiFi. If you aren't using their network, their rules don't apply.

You can use a VPN service to bypass your school’s Internet restrictions. Just connect to a VPN server outside your school to change your IP address. Here is a tutorial on http://www.freevpngame.com/2016/06/free-vpn-for-gaming-windows-mac-android-ios.html.

INSTALL an ENCRYPTED BROWSER like TOR if its a computer or use psiphon instead IF its a MOBILE. Sometimes to bypass internet add  "?.jpg" at the end of site's URL.

You could use a Wi-Fi "Hot-Spot" from a laptop or tablet, if the school walls are not shielded. If they are you would need to go outside.

I agree with about the danger of using Hola but Zenmate is also not secure . One more thing is that due to technical reasons Zenmate IPs are easily tracked and can be banned eaily. This is the reason i suggest to all use a complete VPN to http://www.vpnranks.com/how-to-unblock-websites-at-school/

An approach I used with a highly restrictive employer for access to static sites (it won't work for social media or other things that change frequently) was to prefix an unacceptable URL with the string "https://web.archive.org/20202020202020/".  Actually, any date in the future will do, but seven 20s are easy to type.  If there is a copy of the page you want at the Internet Archive, the most recent one will be loaded.  You may have to click the back arrow in the upper right corner of the view (not your browser's back button) one or more times if the page is no longer on the Internet, as the archive is not too picky about saving 404 pages.  You may also get a popup saying the page is not in the Archive but is available on the network; if so, accept this and after a short while you'll see the page and make it faster for yourself or anyone else to fetch the next time.

Your network are supervised by the provider. If your school limited internet, you can use a VPN to bypass the limit. http://www.unblockgamevpn.com/2015/08/why-you-should-start-using-vpn.html can help give you a more secure connection to your company/school's network. It can change your IP, and unblock the restricted websites, videos and games.

Count on getting caught. Network admins aren't stupid. If I was your network admin and I caught you trying to work round the filters I'd put in place, I'd be very unhappy and probably request a fairly severe punishment including loss of Internet privileges for a few weeks. If you made me look incompetent by succeeding, I'd properly go to work on you and you would regret ever going near a computer. Bear this in mind when it's time for your next fix of gore/pr0n/rekt/lolcats or whatever's so important this week. You might want to wait until you get home.

There's really no way we can answer that - it depends on what your school has chosen to block. Generally speaking, if they block your VPN's servers they also block their website, so you can probably visit different VPNs' websites and see what comes up.
