I don't think it's worth it for the following reasons:

First, getting a degree for postgraduate entrance examination in three wars and eight wars is only an improvement of personal education, but it wastes a lot of time.

Obtaining a postgraduate degree through postgraduate entrance examination can improve one's knowledge and insight in a certain period of time. However, at present, many people regard the postgraduate entrance examination as a utilitarian purpose, rather than simply learning, which is contrary to the original intention of learning.

Second, getting a degree from three wars and eight wars may not be suitable for you.

A person's youth is limited. If he improved himself many times for the postgraduate entrance examination, but spent a lot of time and energy and missed other meaningful things, it would be very unworthy.

Third, there are many ways to improve your experience, which may not be just postgraduate entrance examination.

Sometimes we have to relax, straighten our minds and see what suits us. Whether you are looking for a suitable job or continuing to improve your academic qualifications, you should make a good plan and see which method suits you best in order to make the best choice.

In a word, I think it is not worthwhile for someone to fight three or even eight wars for a degree and for postgraduate entrance examination. Be sure to be thoughtful and correct.
