I have no idea. 
For the first time ever I will be running an epic list of levels 1-5 slow and fast vocabulary.  June 5th at 10am PT.  I am estimating between 2 and 3 hours to complete this. No instruction, no questions or clean up. I will lead the whole list to the best of my ability.  This is a live event on Zoom, no playbacks and no recordings.
