NEW Track your knowledge of grammar points using a 'mastery score' for each grammar point. Mastery scores will be updated automatically as you study grammar flashcards, and you can edit them manually from your mastery summary or from a grammar point. You can view a summary of your mastery of grammar points by usefulness or JLPT level.

Grammar points are referenced by the JLPT level they are first used in, so you can search for all grammar points in a specific level of the JLPT. Use the syntax jltp:x where x is the level of JLPT (from 5, the lowest/easiest, through to 1, the highest/hardest).

NEW You can also combine searches for a specific grammar point or type of grammar point with a JLPT level by adding jlpt:x to any search:

You can also search for grammar points by Kanshudo's rating of how useful they are to you. Grammar points have usefulness levels from 1 to 6. In general, grammar with a JLPT tag will have equivalent usefulness (usefulness 1 corresponds to JLPT 5, and 5 corresponds to JLPT 1; usefulnesss 6 is for harder / rarer grammar points). Some grammar points have a Kanshudo usefulness rating but no JLPT rating because they do not appear in standard JLPT lists, but you would be expected to know them when your Japanese is at that level.
