However, the possibility of free tuition depends on the following factors:
1. school policy: each school has its own policy, including the policy of free tuition. Some schools may provide scholarships, tuition-free assistance or loan relief in various ways, but it depends on the school's enrollment policy and related information.
2. Choice of majors: Some majors may be more likely to get scholarships and tuition-free opportunities, because these majors have greater demand for the country and society.
3. Application conditions: Even if the school provides tuition-free opportunities, it still needs to meet certain conditions, such as working years, work level, performance appraisal, etc.
Therefore, if you are interested in tuition-free in-service graduate students and doctors, I suggest you choose several target schools, carefully study and consult their admissions offices or relevant departments to understand the tuition-free policies and application conditions.
