The cover from the bookstore was kept on, so the cover itself is clean. I will leave the cover on, but please let me know via message if you don't need it. I only solved the first practice test, so the other tests should be clean, but there is one spot of dirt on the first test (see photo 4). I have set the price as low as possible, so I am not accepting price negotiations. Please understand that this is a used item. Please check my profile before considering a purchase. Thank you.
