I found myself remembering almost nothing in the first set of reviews, becuase just one quick test after a lesson doesn’t really leave any lasting impression on my memory. (And it didn’t really improve in subsequent reviews of those items, because the first SRS interval is too long.)
Now I do a bunch of lessons (10-20 depending on how much new information there is to actually remember) then use the self study script to repeatedly test myself on Apprentice 1 items until I can remember them. I make sure I re-read the mnemonic every time I get one wrong. That seems to get me to the same state as most people are in after lessons, i.e. the stuff is actually in my short term memory. YMMV!
(Use the “re-quiz” button at the end of a round to repeat only the ones you failed.)
