This is a course that covers advanced problems from the content of the Teiryo-kai high school freshman math curriculum up to the summer. It's perfect preparation for the summer school mock exams. The course includes a textbook, lecture handouts, in-class exercises with instructor's explanations, and official solutions. The lecture handouts include a lot of notes, including the instructor's verbal explanations. The first day was taught by a substitute instructor, so their handouts are also included. The reservation number and name sections of the course textbook will be cut out before shipping. No returns or complaints accepted.
