Frequently asked questions

How many grammar points are there per JLPT level?

N5 and N4 each cover around 50–80 grammar points; N3 adds roughly 100; N2 and N1 introduce 150+ advanced patterns each. InitialJ's grammar catalogue includes all levels with explanations, examples, and practice exercises.

What does the SRS do with grammar?

The SRS (spaced repetition system) schedules grammar exercises at increasing intervals — reviewing a pattern just before you'd forget it. Each grammar point earns a belt stage from white (new) to burned (mastered), the same system used for kanji and vocabulary.

Is N5 grammar free on InitialJ?

Yes. All N5 grammar points — including explanations, examples, and practice drills — are free forever with no credit card required. Premium unlocks N4 through N1.
