2 new user vars in CP7?

Hi,

Just playing around with CP7.  I see there are 2 new user vars automatically in every new project:

cpQuizInfoStudentID

cpQuizInfoStudentName

I ran a test to display each and uploaded to my LMS.  the ID doesn't display as anything. Can anyone tell me what the purpose of this new var is and why it is a user var instead of a system var?

For the 2nd, it was cool that it got auto populated by my LMS and even dispayed on the Certificate Interaction I put in.  However, it showed up as Smith, Lori instead of Lori Smith.  Is there any way to parse this var to switch the names around or even better to only use the first name if I want to save that to a new var to display throughout the the lesson?

Thanks!
