Shin Kanzen Master N4 Reading Dokkai Jlpt Japan Language Proficiency Test Paperback – May 23, 2018

I have been studying Japanese independently for several years, and until I got this book, I had a hard time evaluating my progress at reading comprehension. It's been a great resource — since I got it, I've been doing an exercise or two every day, and I think it's made me a much more confident reader. The book is well organized for studying, and the answer key gives hints about why each incorrect answer is incorrect. I highly recommend this book as a way to practice reading, even if you are not planning to take the JLPT.
