I’m basically more or less done with WaniKani, so I’ll be using Bunpro and Memrise in terms of apps.
For books, I’m polishing off the last chunk of Genki II and just purchased Tobira and the Intermediate Japanese Grammar dictionary.
My main JLPT specific books I’m working through are TRY! N3 and 500問 because they really helped me for N4, but I’ll also use Kanzen Master N3 for exercises.
What about yourself? Is this your first JLPT?
