This is a mock exam from the Comprehensive Qualification Gakuin for First-Class Architects. It includes three problem booklets and one commentary book, for a total of four books. There are pencil markings on the questions and answer choices, but they have been erased with an eraser so that the correct answers are not visible. Some circles were made with a ballpoint pen, but they have been processed as shown in the second photo so that there is no problem in solving the questions.
