Years of undergraduate study:
The undergraduate education system of world-famous universities is four years, which is the same as the presidency of the United States. Undergraduate education in medieval universities lasted for four years, usually taking only three courses: grammar, rhetoric and logic. At that time, it was mainly to train clergy to preach and teach, so they all spoke languages.
One course a year, three years of study, and the fourth year of practice in the church. This tradition has obviously influenced the setting of the term of office of the president of the United States (that is, as president, the policy is determined in the first year, deployed in the second year, formally implemented in the third year, and the effect of the policy is seen in the fourth year). Therefore, in the eyes of Americans, a president can be tried out in four years.
Modern universities are completely different from medieval universities. Undergraduate education is still four years, because general professional knowledge is divided into three levels: basic courses, professional basic courses and professional courses, one level per year, plus one year of internship, which is exactly four years. The five-year medical undergraduate program is due to the addition of "internship" in the fourth year to show "life events", and it is still internship in the fifth year.
In addition, in Chinese mainland, the academic system for junior college students to pass the unified entrance examination is two years.
