Congrats. =)
I must confess, I never even made it through the free levels of WaniKani – trudging through endless repetitions of the basic kanji and vocab that I learnt forever ago just got to be too much of a drag. I really should give it another stab sometime.
For my own study tools, I’ve bought a few books in Japanese (I’m fortunate enough to live in the same city as a Kinokuniya (major Japanese book shop chain) branch). Also bought the DS version of δΊγε½ in Japanese (because they elected not to release it in English) and found I was understanding it surprisingly easily. Though, learning how to read the furigana when it’s about six pixels tall was a new challenge in itself. =P
You thinking of giving the JLPT a go?
