I purchased this at a cram school and used it for my entrance exam studies. It contains frequently appearing questions carefully selected from entrance exam questions nationwide, allowing for efficient study. The collection of sub-questions, organized by subject, is also substantial and was very helpful. How about using it for a final push starting this winter break? I carried it in my bag, so there are signs of use such as scratches and wear. There is some staining on the inside back cover of the answer key. I solved the problems in a notebook, so there is no writing in the book itself, but I haven't been able to check everything in detail, so I apologize if I missed anything. The part with my name will be marked out with a marker before shipping.
