Where is the math finale of previous senior high school entrance examinations in Shanghai?
When I was in the third grade, our head teacher recommended a copy of Mathematics Final Challenge for Senior High School Entrance Examination published by East China Normal University Press. This book contains the last two questions of mathematics in Shanghai's senior high school entrance examination and the last two questions of mock exams in various districts over the years. There is also a CD with detailed answers to each question, which is very useful. They are sold in Xinhua Bookstore and Shanghai Bookstore, which seems to be compiled by Ma Xiaobin.
