I suppose the main problem is that I don't really understand Spaced Repetition, but I'm trying to review a bunch of cards that I sort of know, but just want to check that I know, so I'm comfortable with going through a large number. I use "Prompt for quality", so I'm hoping that the cards that I score 6 will disappear quickly, while cards that I give a low score will come back. What happens is that I fairly quickly get a "Session Complete" popup saying I have no more cards to review, even though I have turned off "Limit new cards". I thought that turning off limit new cards meant that there would be no limit to the number of cards to review. What am I missing here? Thanks!
