Hello, I am currently studying for a final and I had been sorting the flashcards. I was down to only 30 unknown terms out of the 806 terms I originally started off with. I clicked off the page and when I got back, my flash cards were reset back to 806 unknown terms. I don't have the time to redo them all because I am also studying for another test. Do you guys know how to reverse the action? It would be a life saver!
