    Every government school here uses Linux. And there’s no security (password is “password” even for root account). The only reason it works is because everyone has common sense on what they shouldn’t do. The worst any kid could do is visit a “bad” site on a browser because no one knows how to do anything else.

    Even the exam software assumes you don’t know how things in Linux works:

    • The scores and answers are stored in simple non-encrypted SQLite3 databases at a directory in /usr/share.
    • During the exam, the panel for launching applications is hidden, so you can’t cheat on questions like “What does this tool do in GIMP?” by opening GIMP. But you can just do Ctrl + Alt + T to launch the Terminal and Alt + Tab to switch to it.

    I easily qualified for a State level competition where the education minister visited and had big news agencies visiting that made up a lot of nonsense. You can probably guess what the average student will be like from this
