Before the exam, I also saw Chao Ge's special curve summary, and I saw lemniscate in the examination room. What is amazing is the key topic of 139 drawn at the end of that question. Just Ness! But I want to say that betting is not king, because I did 400 questions in Li Zhengyuan, 6+4 in Li Lin, 8+4 in Zhang Yu and 4 * * * in Polytechnic University, and none of the 36 sets of simulation papers succeeded ... In the end, it depends on the computing power, and I usually lose a lot. Punch in the Weibo with everyone every day, and keep moving. Practice takes 365 days. I feel that this is probably why I can calculate quickly. I think it will be faster if the draft paper is not lost and it takes a little time.
