Lol, I feel your pain. School filters are so annoying. I’ve been using Psiphon for unblocked proxies for school, and it’s been working great. It’s free, and you can download it on your phone or laptop. Just make sure to turn it off when you’re done so the teachers don’t notice anything suspicious.
Also, try not to use it too often. The more you use it, the higher the chance of getting caught.
