There's a lot:
1. Make sure you self-destruct correctly.
2. Make sure there is no information of you visiting vape.gg OR ANY hacks in your web browsers (they can check incognito mode as well so make sure you figure out a way to delete that as well, search up youtube videos for that).
3. Make sure there is no signs of hacks on your PC (like a folder named hacks or vape.exe)
4. Make sure that the cps you get with the autoclicker is something you can click as well or else it looks very suspicious when they ask you to click in the screenshare and you can't click as fast (because they can track your cps)
5. Some people like to put the vape file in a usb and delete the file right before they get frozen. They then disconnect the usb, although the staff can check if any devices were disconnected from the pc so it does look a little sus. Best thing to do is to leave the usb on and have it named to something like 'homework' with random files on it.
