What additional resources could I use with Wanikani?

It’s actually the first month :wink: There are not really any levels, you can work on your own pace.

I also recommend Torii, which teaches you 10K vocab. The vocab in Wanikani is not always useful, as it is mostly there to reinforce kanji readings. Torii even has an option to exclude vocab that WK teaches you, so you don’t learn things twice. And it’s completely free!
