Compared with one of the best, the number three is a little less difficult, but it has an upward trend in recent years. Several big questions are the same as the number one, especially since 2 1, the scores of multiple-choice questions and fill-in-the-blank questions in mathematics have increased, which requires extra practice. I suggest you find a top topic to write about.

2. Examination content
