I’ve just come back to WK after ~15 months. I’ve reset myself 10 levels (5 at first, but it was still too much) and while my initial pass rate on items is horrible (say 20-40%), it quickly gets better (to about 80-90%). Guess it really is easier to relearn stuff. Though there’s three important factors to take into account:
- I had a shit-ton of leeches. I was doing 300+ reviews (which I recently learned is normal… for levels 50-60) for months because I had leeches and stubbornly refusing to stop adding lessons. If you aren’t as crazy as me, you probably won’t have to reset that many levels back (or at all).
- I’ve been reading along with the Beginner Book Club during the break. Maybe that helped solidify some kanji that I wasn’t reviewing? Not sure how strong that effect is since I’ve been using hiragana and a dictionary, though. I’ve also been doing a bit of Anki/Koohi.
- I made use of vacation mode, which I recommend to you as well in case you take a break. That way you come back to a couple of hundred reviews instead of a couple of thousands (depending on which level you are before the break).
