This is a problem book for the Kanji Kentei (KanKen) Level 2, boasting a 99.8% coverage rate. I bought it to study for the KanKen, but I stopped using it partway through. In both the main text and the appendices, there are pages with check marks (✅️) written on them, primarily in the first half. (Photos show some examples.) Please be aware that this is a used item. The text itself has almost no tears or stains, so I think it can still be used. Please refrain from purchasing if you are a perfectionist or are sensitive to used items, as it has been stored by a non-professional. It will be shipped in simple packaging. Thank you for your understanding. - Title: Coverage Rate Measurement Problem Book KanKen Master Level 2 - ISBN: 978-4-8163-5303-4 - Included: Past Questions Canon - Coverage Rate: 99.8% - Past Data: Analysis of 15 years of past data Thank you for looking.
