The first subject, English, if you have a good foundation in English, you don't need to apply for postgraduate entrance examination, because postgraduate entrance examination English is a minor subject, and you can get as many points as possible after crossing the national line, but no matter how good your ability is, the maximum in this subject is 60+/70+. If you get 80+, it's almost impossible. Registration for postgraduate entrance examination is a way for students with poor English foundation, because you still want to study in several places.
The second subject, politics, basically begins to review 3-4 months before the exam. The purpose of signing up for the class is to sort out the knowledge points, because there are really too many contents to be tested in politics. If you can sort it out by yourself, you don't need to apply. The final exam results are similar to those in English, but it is difficult to get high marks in the national exam.
The third subject, the basic course of business, many schools have to take math exams, especially engineering majors. Whether it is one of the best or three books, mathematics is a big head. You can get130+140+if you do well in the exam, and you may get a lot of points if you don't. So it's also here to review and start over. It is very important to see if you can accept the teacher's ideas and methods when you sign up for class. After all, this is the key.
Fourth, the professional business course, which is a question from the school, is also a big deal. I suggest that I find resources to review this subject myself. Many specialized courses in remedial classes are taught one-on-one, and the effect is good, but if I can find the right method, the effect will definitely be better than that in remedial classes, because many students' specialized courses are 140+, which is a graded subject with high grades.
In short, it depends entirely on your actual situation and your ability, but you must stick to it. Many people give up halfway for many reasons. If a person keeps on studying, he is likely to get the desired result.
Personally, I think it depends on my self-control. If self-control is not very good, you can sign up for a postgraduate class to urge me. Postgraduate entrance examination is a lonely process. If you sign up for class, it really feels like everyone is studying together. At that time, I didn't take the postgraduate entrance examination. I studied English, politics and professional courses step by step every day and worked hard on the real questions.
The postgraduate course is mainly about the contents of some regular exams, generally according to the postgraduate syllabus. Take English as an example. In the basic stage, we usually talk about the vocabulary of the postgraduate entrance examination outline and the key vocabulary over the years, as well as grammar knowledge. In the strengthening stage and the sprint stage, we usually talk about the real questions over the years. In English, because the scores of composition and reading comprehension are relatively high, we usually teach reading comprehension skills and methods first, followed by composition writing methods.
