There are many excellent students in Class 3 of Cash Cow in Tsinghua: Crouching Tiger, Hidden Dragon in Tsinghua. Among them, three "classes" recruit students who are basically walked or admitted with extremely high scores, and almost all the best students in Tsinghua are gathered. These three classes are all experimental classes of undergraduate education, belonging to different disciplines, and are collectively called "Yao Qianshu" by the outside world. Because of its homophonic, it is also called "cash cow". 1. Shake: "Yao Ban", an experimental computer science class in Yao Qizhi, has graduates comparable to the top universities in the United States. Yao Ban, formerly known as "Software Science Experimental Class" and later renamed as "Computer Science Experimental Class", belongs to Tsinghua University Institute of Cross Information. Every year, students are enrolled through the National Informatics Olympic Competition, independent enrollment, secondary enrollment in the school, and transferred to other departments in the school to select outstanding students. Most of those who can enter Yao Ban are the top three gold medal players in mathematics, physics and informatics. In 20 18, there were 50 students in Yaoban Xueba, 44 students enrolled independently and 6 students took naked exams, which was called "luxury configuration". Second, money: "money class", Qian Xuesen's mechanics class, is a banner of the national mechanics discipline. In Yao Qian Shu, Qian Ban has the shortest history. It belongs to the Institute of Aeronautics and Astronautics, and its major is "Engineering Mechanics". I mainly study mechanics and mathematics, but I have little knowledge about engineering. Therefore, the money class is more suitable for those students who are interested in mathematical physics, but don't want to do very theoretical basic research, or are determined to learn mechanics or mechanics. Third, the tree: "Mathematical Basic Science Class", mathematical basic science class, not to talk about heroes by grades. The basic class of mathematics, physics and chemistry is the oldest in Shu. Founded at the earliest time, it was once called "Nobel Class" in China. The study pressure and intensity of basic courses are very great, but the training plan is very flexible, which gives students great freedom. They don't talk about heroes, what to learn according to their grades, and what direction to take. In the fourth semester, students will finally determine their major and freely choose their favorite research direction according to their interests.
