A contestant can participate in Quiz only once.
He cannot try more than once. If you make such an arrangement. I think it would be good.
I understand your frustration and all I can say is that it's totally justified, if this really happened. Sadly, nor icopress nor I can limit someone's tries. I expected though for people to complete the quiz for fun, not necessarily for obtaining highest score possible. It is what it is though. Maybe some cheated; maybe some were experienced before joining the forum, as Razmirraz suggested. We may never know for sure unless we actually follow those users' future posts and see how they behave.
Please see also my previous post and edit the post where gave reference to correct answer of a question. (And, as a matter of fact, what's stated there is also not correct So those choosing that answer would pick a wrong one.)
Sadly for them I am ignoring such posts.
Welcome! Feel free to take the quiz whenever you will up for it

My score is 18/21. I hope to do better in the future.
Congrats for the very good score! I quoted your score in full picture below, since your rank does not allow you yet.
