Haven’t done WaniKani, but I have done the JLPT, up to N3.

I was originally planning to knuckle down and actually try studying things in the hopes of doing N2 (or even N1?) this year, but that never happened…

Studied Nakama and Tobira at uni, also bought Japanese for Busy People for self-study. Read the Dictionary of Basic Japanese Grammar from cover to cover, using the example sentences for practice. =) I made a start on the Intermediate dictionary too, but I’ve gotten stalled about twenty percent of the way in…

I also got a flash card app on my iDevices called StickyStudy – the free version includes N5 vocab and kanji decks, but you need to buy the full version if you want more. For N3, I bought an N3 study book with example questions and tests. Not sure where I’ve put it, actually…

I’ve also been playing 二ノ国 on my DS, which has been quite helpful – I was playing it right before I took the N3 test, and encountered a new reading for a kanji which I’d never seen before, and that very reading was then asked in the test. Actually, that’s gotten stalled as well… tsk.
