2, now the senior year is discounted, you can buy second-hand real questions over the years, and you don't write much. Review the whole book and buy new books. After a month and a half, that is, during the summer vacation, I can barely read textbooks and start reading review books. When we are preparing, because we are still reading other subjects, everyone's average daily progress is 7 or 8 pages. It is necessary to understand the unclear basic knowledge points, barely one month before the exam, and then start to do real questions according to the time of postgraduate entrance examination and pinch yourself. At this time, you can basically see your postgraduate level. A conservative estimate of 100 is still possible.
3. If you have a good foundation and make rapid progress, you can read a review book more than two months before the exam, or you can buy a copy of Li Yongle's Beyond 135, which is more difficult than the postgraduate entrance examination, and your heart is devastated. There is no need to buy this book in a hurry. Buy it when you need to do it according to your own progress.
Ps: My friends and I are both economics majors. Because the total score is relatively high, it will be very torturous if we study math during the summer vacation, and then the final score will be delayed! If you take an examination of science, engineering and agronomy in general schools, you should be able to maintain an average level of mathematics from now on.
I have been in the exam for two years, so now I will type this kind of question word for word when I have time, hoping to help you. Good luck!
