The third floor should be similar. According to the statistical difficulty coefficient of real questions over the years, the overall situation of No.2 is relatively simple. I got the second place in this year's exam. There are a few small questions in front of me that need to be turned over several times before they are correct. It's easy to make mistakes if you don't pay attention. The penultimate big problem of high numbers is not unfamiliar, but I haven't solved it for a long time, which leads to another big problem that I can do without time. Finally, I did the problem of 130 and got 12 1 point. It is also important to improvise. Some students expect too much from mathematics and strive for every problem. When they encounter a panic that they can't do for a while, they will play out of order.
