I just thought of this, I'm studying the Shin Kanzen Master N1 plus making a spreadsheet with the nuances and grammar construction. I already knew N2 grammar superficially (no what I am calling nuances between similar forms). If I want to study for N1, should I do the same work with the N2 grammar? I shutter at the thought since it takes such a long time to organize my notes, but if I have to do it, I'll start the work over a period of time. I spent all my time on consumption of Japanese media and not production that I am weak in this area all over.
