Currently I drill next level about 3-4 days before level up.
- Ignore radical names
- Drill kanji names
- Touch very little on “emphasized” kanji readings (just to pass my eyes)
- Drill vocab on EN->JP
- Return to drilling “emphasized” kanji readings
- I also do Kanji writing at this time.
- Wait for the lessons to appear on WaniKani to drill vocab on JP->EN
I use Anki, but I guess Self-study by Rfindley can also do the same.
I drill in a batch of 25 on Anki to make a round number of 50’s or 100’s.
