Part-time graduate students of Zhejiang University belong to on-the-job status and part-time education. Teachers of in-service graduate students in Wen Qi say that students will work at other times during their study, without delay, while full-time graduate students study around the clock. From the perspective of economic pressure, on-the-job graduate students will be more cost-effective and the gold content of the certificate will be high. Its legal effect is the same as full-time certificate, which is helpful for promotion and salary increase, examination and study abroad.
