Generally speaking, the last question of mathematics belongs to the finale, and the difficulty is certain. Especially the last small question, the discrimination is extremely high, and only a few people can do it. Before the college entrance examination, I did the math paper in 2003 and the Jiangsu paper in 2004, and I basically had no idea about the last question. What impressed me the most was one day in senior three. One of our classmates asked the math teacher the last question of the Jiangsu paper in 2004, but the teacher didn't work it out after studying for two hours at night. The classmate also joked that he used more than a dozen toilet papers. The simplicity of Beijing paper is well known. Before the college entrance examination, I also found the Beijing volume, and the whole volume was really simple to fly. I choose to fill in the blanks and work out the result in my mind. The first few big questions were done quickly, but it took a lot of effort to do the last one. Therefore, no matter which paper it is, there is no doubt that the last question is difficult.
