Absolutely essential right before the bookkeeping exam. I tackled the Bookkeeping Level 3 exam using YouTube and three books to build my foundation, but I failed once because I lacked practice problems similar to the actual exam. After that, I thoroughly worked through the online mock exams in this book, and I passed successfully. If I had studied with this book from the beginning, I think I could have passed on the first try. Good luck to those who are going to take the Bookkeeping Level 3 exam! - Title: The Most Comprehensive Textbook for Japanese Bookkeeping Level 3 - Publisher: CPA Accounting Academy - Price: 1100 yen - ISBN: 978-4-8014-6306-7
