Today i’ll like to introduce this book.
Title of book: 日本語能力試験20日で合格N2文字・語彙・文法
ISBN number: 978-4-336-05354-1
This book is quite a valuable book that my students used to pass their N2 and N1. (^_^)
Basically it has 20 days of exercises that prepares you for the exam.
Once you finish this book and understand your mistakes, unless something goes very wrong, if not, you should be passing your exam.
Definitely one of my treasures. (^_^)
