If graduate students who have completed the five-year exam generally need to study for three years, adding up to eight years, then the seven-year program saves 1 year, but it also means one year less clinical experience. The first four and a half years of the seven-year program are undergraduate, followed by postgraduate, and you need to choose a tutor. Like ordinary graduate students, the seven-year program is also called advanced undergraduate course, and it is more difficult to learn science knowledge at the undergraduate stage.
