One's postgraduate entrance examination can't be partial. Moreover, learning a course is easy to get tired, so changing your study can change your mind. In a word, English and math are not easy to learn. When reviewing, start with the science that you least like or have the worst foundation, otherwise, the less willing you are to learn, the less willing you are to learn. Postgraduate entrance examination is actually not very difficult. Of course, it is not a first-class prestigious school. The key is persistence. If you have a plan, you must stick to it. At that time, you will find that many meaningless things will affect you. In short, it is persistence. It is difficult to get high marks in English and math, but it is easy to cross the line.
