I have a deck called HSK which has three subdecks - HSK 1, 2, and 3.
I’d like to learn and review cards from these decks in a random order - some cards from HSK 1, some from HSK 3, etc.
However, when I practice HSK, it seems to be going through the decks in order (despite the fact that HSK 3 is much bigger than HSK 1). Roughly 90% of the cards were devoted to HSK 1 when I started, and now that I’ve finished that deck about 70% of the cards are devoted to HSK 2 (see the image below).
However, my goal is to take cards from all three subdecks equally when practicing the main deck.
I have set the order to be random (see image below), however, this hasn’t worked (it’s been ‘random’ for the past three days).
How can I have the cards in subdecks be presented randomly?
