By learning Lv 61 Kanji along with Lv 61 Vocab, 62 with 62 and so on.
I forgot to put in the tutorial Fake Levels 61 - 70 or 無限 INFINITY - #19 by polv, although it would be best if someone upload it to Memrise; because Anki is hard to use and is problematic sometimes. Also, Memrise can visualize levels.
That Anki is hard to use sometimes, is why I created Spreadsheet version.
Added tutorials:
- Recommended to use filtered deck, but without filter probably also works fine.
