After purchasing, I looked through the pages once, but I haven't used it since and have stored it in a dark place. There are no markings. This book is for achieving an 80% score on the Common Test and passing the Eiken Grade 2 exam. I purchased it a year ago, so there is some yellowing as shown in photo 8. It has been in someone else's hands once. Please refrain from purchasing if you are sensitive to this or if you are looking for a perfect condition item. Please feel free to ask any questions you may have about the item. Thank you for reading this far.
