I will ship it immediately. This is a problem set for the Teiryo-kai Year 3 Science Class, aimed at students aiming for the University of Tokyo, national medical schools, and other prestigious national universities. It contains 30 sets of problems and solutions (with scoring explanations) in the University of Tokyo format. The classes also used this material, with students solving and discussing the same format of printouts each time, but this is a supplementary self-study material and is in good condition. I am also selling the Year 3 Physics Advanced Course textbook. Please consider using that as well.
