N.
Kanshudo displays a badge indicating which level of the JLPT words, kanji and grammar points might first be used in:
indicates N5 (the first and easiest level)
indicates N1 (the highest and most difficult)
You can use Kanshudo to study for the JLPT. Kanshudo usefulness levels for kanji, words and grammar points map directly to JLPT levels, so your mastery level on Kanshudo is a direct indicator of your readiness for the JLPT exams.
Kanshudo usefulness counts up from 1, whereas the JLPT counts down from 5 - so the first JLPT level, N5, is equivalent to Kanshudo usefulness level .
The JLPT vocabulary lists were compiled by Wikipedia and Tanos from past papers. Sometimes the form listed by the sources is not the most useful form. In case of doubt, we advise you to learn the Kanshudo recommended form. Words that appear in the JLPT lists in a different form are indicated with a lighter colored 'shadow' badge, like this: .
