These are 750 (!) brand new intermediate kanji flashcards waiting to be conquered. It’s Volume 2 from White Rabbit Press. Yes, I’ve finished the 300 beginner cards in the first volume (see this post).
Learning kanji is nice, though I really should focus more on grammar. That was my conclusion when I wrote JLPT N4 in Hamburg. The kanji, vocabulary and listening sections were simple, but I was at a loss in the grammar section. A bit surprising; grammar is usually my strong point, vocabulary my weakest. But in Japanese I’ve done so much Iknow that I know a lot of words.
