I am very bad in repeating cards, which were learned a long time ago. I am doing 50 old learned cards per day, but about 40 fail. I would prefer to repeat the first 20 failed cards until I know them again, but Anki is going on with number 21 and so on until number 50. It is really hard for me to relearn 40 cards at once.
How to adjust parameters to have a better experience?
