Waseda Academy Sokei Mathematics November This is the textbook used for the Test Seminar. I tried to erase the writing as cleanly as possible, but some of the ballpoint pen marks remain, as shown in the example in the second photo. Please be aware of this. The mathematics for Sokei (Keio and Waseda Universities) is unique, so I couldn't score well at this time, but thanks to continuing to solve the problems, my score improved significantly by the time of the exam. Similar problems appeared on the tests at Waseda Academy and on the actual exam day, and I was able to solve them with confidence. Highly recommended for those who want to study mathematics seriously.
