This is a sample answer for the entrance exam past questions of the Department of Precision Engineering, Graduate School of Engineering, University of Tokyo. I will be selling a collection of sample answers for general education subjects: Mathematics H10-24, 27, 28, and parts of Physics H23-28, R6, and R7. I recently passed the exam, so I believe this will be helpful. Also, I believe that preparing for graduate school entrance exams at other universities can be quite a burden for those outside the university, so I highly recommend this.
