Please be sure to read the profile. The first photo shows one set of unused past exam questions. These will be included. In addition to the photos, there are a few pages in the answer explanation section with lines drawn on them. There are a few places on the problem pages with calculation marks. All answer sheets are included. I think you can use it without any problems, but please understand that it is a used book before purchasing. It will be shipped in simple packaging to prevent water damage and folding. If you purchase past exam questions from other schools at the same time, I will offer a discount, so please contact me via comment.
