The former is slightly more difficult, which belongs to the medium difficulty of postgraduate entrance examination.
The latter is slightly more difficult, and its computing power has improved, which belongs to the upper-middle level of the difficulty of postgraduate entrance examination (the thinking has not changed, that is, its computing power is higher).
"20 13 Li Yongle pass 660 questions on the basis of mathematics for postgraduate entrance examination" is a book published by Xi jiaotong university press on February 12, 2002. This book mainly includes advanced mathematics (calculus), linear algebra and other basic mathematical problems.
We have two basic ideas in the design of the topic: one is the simulation of multiple-choice questions and fill-in-the-blank questions, and the other is the basic plate paving the way for solving problems.
