Re: Will some random questions repeat before all are used?
 

Hi, it is possible to have a truely random selection on N out of M questions (given N<= M).

e.g. This can be done by drawing random list size N times and removing the selected item each time.

So getting repeated  question when N<=M should be considered a bug.
