Develop the good habit of doing the questions carefully and do a good job of collecting the wrong questions. . I think many students will do a lot of basic stage problems when they read Tang Jiafeng's 20 17 "Notes on Mathematics Relay for Postgraduate Entrance Examination 1800 Mathematics I". The review of postgraduate mathematics needs enough patience and perseverance. When you encounter problems or feel tired in your study, you should take a proper rest or go out with other students for proper exercise to adjust yourself, and exchange experiences and skills with fellow researchers to make up for each other's weaknesses. It is not a problem to concentrate on the postgraduate entrance examination for 2 months. You can also look at other materials of Tang Jiafeng's postgraduate mathematics strengthening stage and sprint stage.
