1, different grades. Doctor is a name for graduate students who are studying for a doctorate, and it can also be used to address people who have already obtained a doctorate; A master's degree is a postgraduate degree between a bachelor's degree and a doctor's degree; Postdoctoral is not a degree, but a work experience.

3. The requirements for obtaining the corresponding title are different. The process of obtaining these three titles is that you must first pass the college entrance examination and enter the university, and then you can get a bachelor's degree after graduation. If you get a bachelor's degree, you can take a master's degree. The minimum retest scores of each school are different, and the minimum admission lines in the east and west are also different. If these two conditions are met, you can participate in the master's interview.

4, the demand time is non-stop. A postdoctoral fellow is not a higher degree than a doctor, but a temporary job. Master's degree and doctor's degree are actually called graduate students, but what we usually call postgraduate entrance examination and postgraduate entrance examination insurance mainly refers to postgraduate entrance examination. The postgraduate education system is three years. Generally, I will take basic courses in the first year and go to the laboratory to do projects with my tutor in the second year.
