I have repeatedly noticed that the Kanji classification by JLPT level are incorrect… this leads to the fact that renshuu schedules by N-level turn out to be incorrect. I am not quite sure why this is, given the fact that kanji included in each category doesn’t really change (perhaps minor additions).
One example - 覆 is N1 in renshuu, when it’s actually N3. This is just one example.
This is unfortunate for me as I used the kanji renshuu schedules as a reference for kanjis at each level.
It is possible you are misunderstanding it with 覆う which, as indicated by renshuu's dictionary, is a N3 term (not kanji!)
This is most likely. The Renshuu kanji dictionary says it is N1 like all the others. Encountering words is different.
One may even be likely taught words and their reading long before you get to study the kanji used in it. I'm pretty sure it's been like that since the beginning, now that I think of it.
I have encountered this phenomenon on social media accounts before. Some will teach things I recognize, some 1 or 2 levels higher than where I am. Words with advanced kanji that may not be taught until later. Instantly familiar. So sometimes kanji isn't taught in depth until later.
