I’d like to take the JLPT N2 this December, and if that goes well, start preparing for the N1.
Specifically for the “learning grammar” part, and only limited to that one part, I’d like to know if it will be enough to study and drill grammar using Bunpro reviews, or if those who passed supplemented their grammar study with additional materials, e.g. textbooks or JLPT prep books.
If using Bunpro is actually a good enough preparation for the grammar points, that would free up some time for reading books, practicing listening, etc., which would help a lot. But I worry if my grammar skills will lack.
