I used this book to study kanji for the N4 exam. I found it very easy to use, and learnt from it very quickly compared to other Kanji books I had used.
It covers the new kanji in each chapter from numerous angles. This includes practicing writing them, filling in gaps in words, matching meanings to images and written text, matching kanji to their pronunciations; writing their pronunciations; and a lot more.
This book was never boring and can really help a person to gain a good knowledge of the Kanji it covers in a short time.
