Great idea

A great idea of mine is some sort of builder qualification, that students can choose to do instead of a trial if they want to save some time. the “qualification” method would make them type paragraphs about what they know about the information needed to pass builder trial.
It would ask questions about 2’s complement, Bitwise, etc., and later a staff member could check and see if their knowlege was valid, or if they needed to retry

The trial is also for applying your knowledge in the game

If you were to implement such a system, an obvious flaw would be that students could take all the time they want to answer, e.g.: They can think a lot about
how to answer each question. If we now were to fix this by implementing a time limit, people that are non native speakers would have less time.

And they can ask for help
