Especially nowadays due to C0v1d, in most schools, universities, etc, you will have to take your tests online. To make sure the implemented methods work, your ... will most certainly have to run trials.

These trials could be in the form of a nongraded test.

If the average score of the nongraded test is very low (but it at least needs to appear unsabotaged) your teachers/professors/etc will definitely lower the actual tests difficulty (and vice versa). So the last thing you want to do is to be cheating (by looking up answers) during those trial tests as you'll be indirectly sabotaging yourself. Also don't not take part and or hand in an empty/completely wrong test.

To take full advantage of these kinds of trial tests, you need to inform as many people as possible without the teachers/professors/etc finding out.
