No, I haven’t decided to take the JLPT1 at this point, but I have been hitting the kanji again, many months after my successful clearing of the JLPT2.
In reviewing my flashcards, I’m actually sort of amazed I was able to retain so much. While a lot of times the knowledge will be incomplete (I’ll remember an On reading but not a Kun reading or vice versa), it’s still there in parts. The human mind is an amazing thing, and in a way it’s given me further motivation to keep up my independent Japanese studies, as I know that further progress is still very much possible.
One area I feel I lack in which concerns me is a proper understanding of Japanese culture, and how to read certain situations and then speak the language accordingly. Put me into a raw Japanese business setting, and even with my Business-Level Japanese, I’ll flounder because I’ve never studied about Japanese corporate settings.
