Don't fill it in. Don't write it on your resume if you have a low grade in the initial exam of the postgraduate entrance examination. Because if the initial test results were not so outstanding, I wouldn't write. If a subject is well done, it can be written separately. Undergraduate school, major, specialized course, score/grade point. Those with high degree of relevance and good grades are written in front, and those with low degree of relevance and poor grades need not be written. If you have participated in some training related to applying for a major in your spare time, you can also write some appropriately.
