I often find that if I have a lesson I want to retest on it won't let me & says:
"To kwiz this lesson again, save it to a notebook and kwiz against it until you have nailed it."
but when I add it to the notebook it then says:
"This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like."
apologies if this has been asked before, but I did search & check the FAQ but didn't find anything.
many thanks :)
