Set of the latest information I's study notes and answer key. The notebook has writing on about three-quarters of the pages. Writing in orange ballpoint pen becomes invisible when covered with a red sheet. Please check the images. There is a name written on it, so it will be blacked out with a marker before shipping. Please consider only if you are not concerned about minor stains or scratches due to it being a used item. I also have textbooks, reference books, etc. for sale.
