Li Lin’s four sets of volumes will be released on December 4, 2022.

Li Lin’s 4 sets of papers are basically a set of must-do papers for the postgraduate mathematics entrance examination. The question style is close to the real questions and is very comprehensive. After completing the real question papers from 2005 to 2012, I then took the four sets of Li Lin papers in 2022. I found that the difficulty had obviously gone up a level, and the knowledge points examined in the questions were not so obvious.

When most students receive a question, they first analyze which knowledge point it examines, and search in their minds for the key points, difficulties, and areas that need attention about this knowledge point. This method has been tried and tested many times when doing early real test papers. The purpose of the real test papers to examine knowledge points is very obvious.

But Li Lin’s 4 sets of papers will hide them and not tell you, and will often encapsulate them through some other knowledge. This not only increased the comprehensiveness of the question, but also made it impossible for me to quickly construct a problem-solving context in my brain after I first got the question. I could only start from what I already knew and cross the river by feeling for the stones. This requires students to be cautious and comprehensive: they can not only fully explore the topic information, prevent a single perspective, but also ensure that the calculations are error-free.

Li Lin, the "famous mathematics teacher" of Dalian University of Technology, won 80% of the real questions for the postgraduate entrance examination

In the 2018 National Master's Unified Entrance Examination, there were "magic questions" in the mathematics subject. A man named " The example questions given by teachers at "Li Lin" in the pre-examination video are very similar to the actual postgraduate examination questions. Netizens pointed out that Li Lin's "hit rate" on the questions was as high as 80%, and he even repeatedly emphasized the second-order difference of the super-class. "Winning a few questions every year is already very impressive. This teacher only bets on the original questions of the major questions and the original proof questions. He even guessed the second-order differential of the super-general, and emphasized it repeatedly."
