I reached N3 level in the first year of Japanese and then my grammar knowledge pretty much stagnated
I think I got involved in too many things (for grammar I was literally writing a textbook as I’d go with learning it). Then I got involved into improving both Core 10k and a katakana vocab deck on Kitsun… and life happened… and I’m not the perfect person when it comes to discipline so…
But oh well, things are going back to place bit by bit I also have Russian to deal with, so my attention needs to be divided.
For grammar, I followed Bunpro’s JLPT list, checked a bunch of resources online and took notes as I’d go. That’s why the textbook idea came up. I realized there’s a need for a better balance between depth of grammar explanations and ease of learning.
I didn’t follow any specific textbook. However, once I’m back to grammar, I’ll use the shinkanzen series. I like how they order their grammar books by similar grammar. I think that not enough grammar sources are willing to help differentiate different grammar structures, which only leads to you knowing 5 different ways of saying “the same thing” and no idea which one is best, even if the nuance is small.
Thank you for the kind words
