thx uIn order to qualify for a voucher, you must:
1) Be an active member of the CompTIA Instructor Network
2) Attend all the sessions for at least 110 minutes for a two hour session
3) If you miss a session, you make it up by watching the On-Demand, which you can access using the same link as what you use to get to the live session
4) Complete all the sessions before two weeks after the end of the last session, when @Stephen Schneiter runs his report of attendees. In case there are discrepancies, make SURE you download and retain your Completion Certificate.
Hope this helps.
