1, difficulty: * * * The simulation test paper is moderately difficult to make, which is very suitable for simulation exercises, but it is difficult to surpass the simulation test paper. The above topics are novel, many of which are difficult to find and require a large amount of calculation, and are suitable for students who sprint 140.

2. Content: * * Create simulation test papers including fill-in-the-blank questions, multiple-choice questions, solution questions, etc. It covers all the knowledge points of postgraduate mathematics, and pays more attention to the understanding and application of knowledge points while surpassing simulation questions, especially for the examination of difficult and comprehensive questions.
