General GMAT Questions and Strategies | Regarding Kaplan Quiz after registering Kaplan GMAT Premier 2017

Hi,

I recently brought my Kaplan GMAT Premier 2017 book and have registered the book online to get my online resources.
I have seen that the online resources give plenty of quizzes and also we can customize our own set of quizzes.
Do all the quizzes have different questions or do the questions keep repeating after some time?


Thanks in Advance.

Regards,
