This collection primarily features problems suitable for Tokyo Tech, Hitotsubashi, and the science and engineering departments of Waseda and Keio universities. If you find past exam questions challenging, starting with this problem set will be just right and easier to solve. There are also a few problems that resemble those from the University of Tokyo, medical schools, and Tokyo University of Science. Regardless of which university you are aiming for, this is a collection of excellent problems that will provide you with useful knowledge, so I highly recommend it.
