There are writings only on page 2 of the answer booklet and page 3 of the problem booklet. Also, there may be oversights. There are scratches, creases, and signs of use. Please refrain from purchasing if you are nervous, as this is stored at home and inspected by an amateur. Shipping will be within 4-7 days, but I will ship as soon as possible. Please feel free to comment if you have any questions. Thank you. (__)
