Here is a book that aims at cultivating the grammar needed for N3 of the Japanese Language Proficiency Test.
The book is divided into the following three parts: Part 1: 'Mondai Shokai' (Format of the grammar questions and an overview of how to solve them) Part 2: 'Jitsuryoku Yoseihen' (Study of the three different types of questions, plus language knowledge and skills) Part 3: 'Mogi Shiken' (A mock test so the learner can confirm his/her level) In 'Jitsuryoku Yoseihen', the exercises in 'Bun no Bunpo 1' and 'Bun no Bunpo 2' are arranged so the learner studies the grammar form and the meaning and function separately. This section also has detailed explanations and plenty of practice exercises.
Unlike the N1 and N2 books, this one comes with a translation in English and Chinese.
This book not only ensures continued strengthening of the learner's ability in grammar, but also his/her overall ability at the upper intermediate level.
