Although, it is possible to power through to level 60; the main point of WaniKani is, are you able to read real Japanese text?
Looking back, some things that can be done better
- Join more book clubs. Not (at all) to test my Kanji skill and reading without Furigana; but instead focus on learning contexts and comprehension
- Learning other-than-visual aspects of Japanese language, for example, listening - somehow, certain YouTube channels are relatively easy to be listened to.
But, how did I read level 60 at that time?
- Practicing recall (e.g. reversed flashcard) - although my tactic was EN => JP quizzes before starting every levels, I suspect there are other ways.
- Reaching out to JP references early on - [Userscript] WaniKani JJ External Definition from Weblio (JP) and Kanjipedia
- This is quite important as, not only English is not my native language, but also that JE dictionaries tend to explain as translations, but JJ tend to be more of interpretation sideways.
- There are certain resources I have only found in JP, e.g. dictionary for related words (類語辞書), progressive dictionary.
I used a lot of UserScripts as well. At least - No Cigar, Double Check, Reorder, and Self-Study.
Even when I am overwhelmed, Reorder helps.
