After hearing about Anki and FSRS, I'm trying to use Anki it for learning a new language. I'm a little frustrated and overwhelmed at the options. I'll look at a deck that says I have nothing to review, but I know I'm not confident in my retention. Besides a custom study, is there a way to go through a deck whenever I want? This seems to be more of a problem for smaller decks, say a dozen items. FSRS seems to do better with large decks where the statistic advantages come more into play.
