Yes, there are generally not too many restrictions on on-the-job postgraduate entrance examination. But only if your score is enough.

On-the-job and interdisciplinary. Specialized courses may be a bright spot for you, and another point is that most of the in-service graduate students have left school, and the learning atmosphere may not be good enough. It is suggested to take online courses, such as one's postgraduate entrance examination in heaven. One is to solve the learning difficulties, and the other is because many people are already working, and their time may not be particularly free. Sometimes I can't attend remedial classes, and online classes solve all the problems.

However, since the postgraduate entrance examination is confirmed, it is better to prepare as soon as possible.
