This book is well-used and shows signs of wear, including tears. There are also writings inside. Please be assured that the writings related to the answers are not considered a problem. This is a collection of past exam questions that is no longer available. Similar questions to those in past exams are often included in the yearly exams, so I highly recommend solving these. The questions in this book are not even included in this year's Complete version. In fact, on the day of the exam, I felt that solving the questions from this book, which are from over 5 years ago, was more helpful than the Complete version. This is the perfect problem set for national exam preparation. It includes a separate booklet with photos. - Title: Dental Hygienist National Examination Question Collection 2018 Edition - Edition: 22nd to 26th Exams - Publisher: Ishiyakushuppan Inc. - Year: 2018 - Contents: Question collection for national exam preparation - Features: Includes detailed explanations Thank you for viewing.
