Strong disagree.

I learned multiple languages this way. I think you’re better served by turning off the counter for cards remaining, and studying more often. Otherwise you’re not doing SRS at all.

One can’t remember 2300 Kanji as an aha-moment each.

Drilling all the possible combinations of Hangeul characters for recognition speed is very effective, but most cards won’t be an aha-moment.

One can use premade lists of vocabulary and prioritize vocabulary encountered in study material/real life. You’ll have to learn all the other vocabulary eventually anyway.

Decks with huge amounts of example sentences and audio simulate real conversation and drill listening comprehension and applied grammar.
