This is something to humble all of us eager disciples of kanji on WK…ES students in Japan learn just over a thousand kanji by the end of grade 6. See the chart here for a breakdown by year [https://www.mext.go.jp/a_menu/shotou/new-cs/youryou/syo/koku/001.htm].
A few years ago, when I was teaching in Japan, I passed the seventh grade of Kanken (漢検) (equivalent to ES grade 4). I thought I was so clever, but also realised that I barely knew any kanji in the grand scale of kanji knowledge. I also felt like a bit of a fraud as I just had studied the relative kanji in order to pass the test. Anyway, after coming back to WK recently and reaching level 19 (just over 600 kanji), I have again reached the typical level of a fourth grade ES student lol …my point? I’ve still got such a long way to go… Good luck to everyone on the kanji journey.
