Used book. It was used during the exam period, so there is a sense of use. I erased the pencil marks, but there are some blue ballpoint pen lines in the problem set and answer explanation sections. (Especially in the answers and explanations) Also, the answer key was detached and used. Please check the photos for details. I don't think it will interfere with solving the problems, but if you are concerned, please refrain from purchasing.
