The advantages of this teaching mode are as follows: ① The learning mode is flexible and you can study online anytime and anywhere; ② It is suitable for on-the-job amateur study, which effectively solves the contradiction between work and study of on-the-job personnel; (3) Adopting the credit system management mode. Students can apply for graduation after completing the total credits required by their major within the effective study period (2.5-5 years for non-medical students and 3-6 years for medical students). The credit system abandons the traditional form of academic year education, and its flexible learning cycle is more suitable for on-the-job personnel who need to continue their studies after joining the work.
