1, medical college
The path of career development is quite clear. Undergraduate → graduate → hospital, basically, as long as you don't have too much rejection of the profession of doctor, you are not in a hurry to find a job, but you may be tired when you are young, but the social status of doctors is really high.
2. Finance or Economy
The employment situation was particularly good in previous years. It seems that it has leveled off in recent years, but overall it is still very good for employment, and the employment development is quite good. The salary level is still good. In fact, like programmers, they are also tired, but the salary is really much better than other industries. But the college entrance examination score is really high, and it is difficult to take the exam.
3, mathematics or physics or computer
This is my own selfishness. If you are a science student, it is really a good choice to choose a school of mathematics, a school of physics or a computer. Forget the computer. After all, the Internet industry is hot. Mathematical physics and chemistry is mainly because the foundation of mathematical physics and chemistry is really important, and the major of mathematical physics and chemistry in Peking University is really strong. Therefore, as long as you can learn, it is really easy for you to change your major (such as studying finance) at the postgraduate stage, which belongs to a major with a lot of accumulation.
In fact, most students who graduated from Peking University will not worry about employment, so in fact, although I work in a department where it is difficult to find a professional counterpart, my classmates around me are not really looking for a job. Many people who study in Peking University still have great scientific research ideals, and choosing what they like is the most important!
