Yes According to official website and the Graduate School of Jinan University, it is known that the Graduate School of Jinan University can be rebuilt, but it will waste credits. In principle, summer courses are not allowed, and there are no unpopular courses. Unpopular subjects (courses that can't be taught in summer school) should be retaken first and then retaken. Hot subjects (computer, advanced mathematics, etc. ) you can consider a direct retest.
