Judging from the review experience of most people, the review for postgraduate entrance examination is 6- 12 months. 18 is about 20 17 February 25th. So you should be a junior last semester, almost at the beginning of your understanding.
(1) The most important thing at this stage is to determine whether to take the postgraduate entrance examination and determine the target institutions and majors.
(2) In addition, if you want to start reviewing, then math and English can be advanced subjects.
(3) Politics can be put off so early, there is no need to start reviewing now.
In English:
Basically, all posts will be recognized, and words should be memorized in advance. I also highly recommend the app "Postgraduate Entrance Examination Spring Question Bank" developed by Du Wen Education, which has exercises specifically for various types of questions, such as cloze, reading comprehension, composition and so on. , and the real questions of the past ten years. It's important to do real questions.
In mathematics:
Basically, mathematics is the hard bone of the postgraduate entrance examination, so we must work hard to do a good job in the topic. In terms of data, it is enough to do thorough math books and real questions and add several sets of simulation questions. But on this basis, methods and notes summary are very important.
