First off, I am new and was asked to complete the certification so I could start running local tournaments. I missed two questions, and one of them was because the text wasn't clear in the Official Rules. I had just finish reading the rules before taking the exam.
The question was "A player asked for a deck change" I don't remember all the possible answers, but these were the ones I wrote down after I got the question wrong...
A - Never, unless cards are damaged.
F - None of the above.
Rule #17. Deck Changes
Deck changes will be on the dealer push or level changes or as prescribed by the house.
Players may not ask for deck changes.So I obviously pick "F". I got the question wrong, it told me "A" was the correct answer. I'm not trying to bitch because I only missed I think two questions but "A" starts with "Never". Never means never, last time I checked the dictionary

I just think it was a misleading question.
tl;dr: I think this question sucks, can you guys review it for future TDA's.
