Six years. One of the attractions of the strong foundation project is to continue to study for master's and doctor's training modes. Through strong basic courses, candidates can not only avoid the brutal competition for postgraduate entrance examination, but also shorten the joint study time of bachelor's and doctoral degrees. The strong foundation plan adopts the training mode of small class teaching and continuous reading, and will inspect the candidates from time to time. Those who fail to meet the requirements will quit the strong foundation program and join the study of bachelor's and doctoral degrees. A candidate who passes the exam can graduate in six years at the earliest, and the strong foundation program of colleges and universities will dynamically enter and exit the examination mode and time node.
