A lot of life things happened and while I’m not actively studying for the exam, I know that I’m still gonna aim for the N2 at some point in the near future. Maybe when this is all over 
Like I said in my previous post, I’m just maintaining my proficiency and that’s pretty much going well 
For the N2, I’m a big fan of Shin Kanzen for textbooks when it comes to reading and grammar. Then for additional grammar ('cause one source is never enough):
- I use the Japanese grammar dictionary which was helpful BUT IT’S SO DRY
- YT channels like 森の日本語 for specific grammar points and Misa for explaining different nuances to similar grammar points.
Your level in WK is already good to go for N2 in terms of kanji, if you get to level 60, that’s already just a bonus 
For vocab, you’re really just gonna need to SRS a lot, so PLEASE DON’T USE ANKI OMG YOU POOR SOUL 
I used Kitsun which is much better and there’s so much to it + more to come, but…uh…gotta be honest, I’m part of the team so that’s probably sounding biased and I feel like I have to stop at “I used Kitsun and I loved it, it worked for me”
For listening, I’m not sure if there are tools yet for it that have been considered really really helpful so it’s unfortunately the good ol’ podcasts + anime with jp or no subs.
