Nihongo So-matome N3 Grammar covers around 230 grammar points for the JLPT N3. It's structured as a six-week programme at two pages a day, with study material on one page and practice questions facing it. Similar grammar concepts are grouped together each week, which helps with patterns that are easy to confuse. Each week ends with a review exercise in JLPT format, and there's a mock test at the end. Audio is downloadable from ASK's website. Answers and detailed readings of correct sentences are in a separate 28-page booklet included with the book.
This is the revised and expanded edition (May 2022), with colour, mock test, weekly review exercises, and an expanded answer booklet. Translations are in English, Chinese, and Korean.
This is the weakest book in the N3 So-matome set. The grammar explanations are brief and sometimes unclear in English, and if you're encountering a pattern for the first time, you'll need another source to actually understand it. What it does well is drill. There are a lot of practice questions in JLPT format, and the grouping of similar grammar points makes it easy to see which areas you're shaky on. So it works as a diagnostic tool and structured review, just not as a teaching resource. For grammar preparation that explains the material properly, Shin Kanzen Master N3 Grammar goes much deeper.
