You would absolutely wipe those apps. Guardian might well reinstall, but the others won’t, because they aren’t installed the same way. The last time someone asked this on reddit, a response went into detail about why it’s a fail, maybe you can find that post (assuming it wasn’t deleted by the poster, and the responses are still there).
But the gist was that it isn’t worth trying because it ends up being too easy to detect even if the apps did reinstall themselves. Since there’s a degree of financial liability involved, it isn’t like the experiment is consequence free; schools can, and will, send a nasty bill for it. There was a bit of a problem with it at some schools here and there, and it was generally considered to be the same as destroying the device. While that’s dumb as hell, you or your parents would still be on the hook.
Now, if none of that means anything to you, do what you’re gonna do, I ain’t your dad. Just go into it aware that it probably won’t end with you having a totally open device for free.
