We understand that you may want to take a second or even third pass through the questions in RADPrimer. The new date filter allows you to do that and more! The following is an example of how you can use it to see questions as "new to you" that you may hay have already answered in the past.
If you had a testing event on October and would like to take a second pass through the questions you would enter a date, 10/01/2013 for example, in your profile settings. This date will now be the line in the sand where all quiz questions taken prior to this date will not count as taken. Because this is a global preference it automatically be will be used for new quizzes created in the Advanced Quiz Builder and Comprehensive Learning Engine.
You can override this or any other preference for individual quizzes by entering new values in the fields and the will only apply to that specific instance.
