I passed N2 many, many years ago and am preparing for N1 next summer. Kanji and vocabulary has always been my strong suit, and grammar my Achilles heel, so I was really glad when I learned about Bunpro - it is exactly what I was looking for.
Sometimes knowledge of the basics has been less than ideal, so I’ve gone all the way to N5 and N4 material and am working my way through pretty steadily. Some stuff I know extremely well, and it doesn’t make sense to get all the streaks. If I click “I know this” does this mean that I will never see it again, or does it come up in the Ghost Reviews?
