Since I signed up for the N3 this year I was looking for a resource that would help me focus on whats on the exam. For the N4, I had gotten N4 スピードマスター which I like, but when I was looking up the reviews on the N3 series, people said there were translation errors on the grammar book that made it kind of pointless. I had also bought パターン別 N4 which I actually hated since the grammar explanations were terrible.
However, this time around I was thinking of getting the grammar and reading editions 日本語総まとめ and was just looking for the experiences of other fellow Wanikani members. I also plan to get one of those exam books, （日本語能力試験）
Hi! I’m preparing for n5 or n4not sure if I can get to n4 level on time. I use these two, I’m not English native but I think they are pretty good. Both are easy to use and consult. I also have the same exam book but the lvl 5 and I think it’s very helpful too.
I used N2 grammar sou matome in Japanese class and the teacher always said the translations and sentences were pretty awful so she recommended shin kanzen master for better example sentences.
I do like the way sou matome organizes their grammar lessons though. Consider getting both to have awesome organization with all items and extra explanations in the kanzen master.
