I’m wondering how much grammar still remains if you finish all 930 items in Bunpro.
The famous “A Dictionary of Basic/Intermediate/Advanced Japanese Grammar” book trilogy covers 600 items. So only two thirds of Bunpro if you just compare the numbers.
But my favorite grammar dictionary, the “日本語文型辞典 - A Handbook of Japanese Grammar Patterns for Teachers and Learners” claims to be covering 3000 items. I guess they count multiple meanings of items because with 700 pages there should be four items per page and it doesn’t look like that. But on the other hand I now know N5-N2 completely with 730 items in Bunpro and just by going through the book and checking some items I still find quite a lot I don’t know.
So I wonder whether there’s actually grammar left that isn’t covered by JLPT N1. Besides all the colloquial and dialect stuff that you usually won’t find in grammar books of course.
And no, I don’t want to learn it, I’m just curious. At the moment I rather think about postponing the remaining N1 stuff for a very long time…
