An impressive collection of grammar points throughly arranged by use cases (reason, presentation, etc) , finishing with intensive reviews, common misconceptions in Japanese Grammar and the unavoidable practice tests. By far the best hardcore Grammar practice you need for passing the JLPT. However, I would daringly say that it goes beyond that, as I am sure this book will be my companion for the years to come in my improvement of daily Japanese. One criticism though, for the level of questions it entails, the answer sheet leaves a lot to be desired. It would have been pretty useful if the authors provide the correct order for the ‘文書の組み立てる’ exercises. Aside from that, it is a must for all JLPT N2 applicants and Grammar lovers in general. You are brave if you go with this as your first material to study for the exam; I would recommend trying the “Sou Matome N2 Grammar” or “Try N2 Grammar” book first.
