The full credit system is different from the academic year credit system in terms of teaching plan, course task setting, class management, etc. The credit system was developed from the course selection system proposed by the German educator Humboldt, and originally originated at Harvard University in the United States.

In recent years, many domestic universities have begun to promote the reform of the full creditSystem. The full credit System is based on the premise of course selection, taking credits and grade points as the measurement unit of students' learning quality and quantity.
