I would like to know what will happen if I get my guru-level kanji wrong and it goes down to apprentice-level. To be more specific, will I be able to learn/review the vocabulary derived from that Kanji. Or, does this incident pose other effect of which I do not know? (I mean, apart from downgrading that guru Kanji to apprentice level)
This has been bugging me for a while, and I couldn’t find the answer anywhere.
Thank you in advance.
