In the first case, it is not too late to prepare for the postgraduate entrance examination. Because you have the foundation of professional courses, as long as you prepare public courses in the rest of the time, the possibility of successful landing is still great. This kind of students, if they want to succeed in this major, I suggest you take an examination in our school.
Because our school has a relative advantage in our school's exams, especially in the second interview, the interviewer (maybe the teacher who gives you a class on weekdays) will take care of it more or less.
Other conditions for postgraduate entrance examination
It is a cross-examination, that is, a cross-professional examination of graduate students. Caution is advised. Because the cross-examination means that you need to prepare public courses in the next limited time and spend a lot of time reading professional books. Judging from the time, it is probably too late.
Of course, anything is possible, and you can't directly deny it just because you have passed the exam. This situation is not impossible, and there is a safer way to set yourself a goal that is not particularly high. For example, the institutions applying for the exam are not 985/2 1 1. There is still a great possibility of a successful landing in this way.
Cross-exam+math exam. If you want to take the math test across majors at the same time, it is recommended to leave more time for preparation. Not because you are not good enough, but because we should respect the facts. Mathematics, especially those courses and exercises with the highest difficulty coefficient, can't be solved in a short time. I suggest you take a look at the average score of the mathematics postgraduate entrance examination in recent years, and you will know it then. Of course, in this case, except those who are gifted in mathematics.
