Can my college see my internet activity if I use a VPN?

I’ve been using a VPN and it seems good so far. But if I connect to my college’s WiFi, would their IT department be able to track my internet activity anyway? (Not that I’m doing anything that I think would cause any trouble or anything. I just like my privacy.)

The best thing when you are in a public network where you do not have control, the most desirable thing would be to be connected to a VPN, since in this case if you used the UDP protocol and port 1194, they could intuit that there is a connection to a VPN but not They could see what you are sending in this tunnel, so in short they will not be able to see your activity on the internet, only when you start the connection to the VPN

No. That is the whole point of using one.

Well all they can see you’re using a VPN, but they can’t see the specific sites you visit or content you access while connected to the VPN.

NO! Just be careful with what VPN you use! DO NOT EVER EVER use ANY FREE VPNs!!!

They’ll definitely be able to see that you are using a VPN. Most schools and other public networks end up doing SSL decryption, your searches may be viewable in that case without a VPN or tunnel.
