This is the 1st session of the 2017 Todai-style, Difficult University-Level Descriptive Mock Exam held in May. It is for science students. The subjects are Japanese, Mathematics (for science students), English, and Science. The Japanese and Science sections are untouched, and the answer sheets are included in unused condition. The Mathematics section does not have an answer sheet, but there is almost no writing on the question paper (there is a small memo on question 4), so it can be used as is. The English section has a lot of writing on the question paper, as shown in the photos. It's just pencil notes, so please erase them before use. Answer explanations are included. Please use it to test your skills just before the actual exam.
