but i wouldn't be predictable if i didn't put forward one or two quizzifications to wonder whether that is a proper word.
QUIZ? yes;
QUIZZIFY? just about;
QUIZZIFICATE? no. it is not a word. stick with QUIZ (v);
QUIZZIFICATION? don't push your luck son;
QUIZZIFICATIONS?

google says 24, all of which are wordlists. so it has never been used as a functional word. i'm rather afraid that words like this devalue the language. and wordgames which allow such aberrations are, imo, not about words but numbers.
