実力アップ! 日本語能力試験 N4 読む: The Preparatory Course for the Japanese Language Proficiency Test N4

I strongly recommend against using this book for N4 study, it contains a large number of N3 words.

For example in some sections where I was counting, every 3-5 questions contained an N3 word.

This led to much confusion and if I hadn’t been checking, it would have seriously undermined my confidence. It also prevented me from using the book to test my speed under test conditions.
