Li Lin's four sets of papers are basically a set of papers that must be done in mathematics for postgraduate entrance examination. The question type is close to the real question and very comprehensive. When I finished the real test paper in 2005-12 and made four sets of test papers in 22 years, I found that the difficulty obviously rose to a level, and the knowledge points of topic investigation were not so obvious.
Most students get a topic, first analyze which knowledge point it examines, and search for key points, difficulties and points that need attention in their minds. This method has been tried and tested in the early real test papers, and the intention of investigating knowledge points in the real test papers is very obvious.
But Li Lin's four volumes will be hidden from you, and they will often be packaged by some other knowledge. This not only increases the comprehensiveness of the topic, but also makes it impossible for me to quickly build a context to solve the problem in my brain after I have just got the topic. I can only cross the river by feeling the stones from what I know. This requires students to be cautious and comprehensive: they can fully tap the topic information, prevent the single perspective, and ensure that the operation is not wrong.
Li Lin, a "famous math teacher" in Dalian University of Technology, took part in the postgraduate entrance examination.
In 20 18, there was a "mystery" in the mathematics subject of the national postgraduate entrance examination. The example given by a teacher named "Li Lin" in the pre-test betting video is very similar to the real question of the postgraduate entrance examination. Netizens pointed out that the "hit rate" of Li Lin's bet was as high as 80%, and even repeatedly emphasized the second-order difference of Chaogang. "It is already very awesome to bet on a few questions every year. The teacher just gambled on the original title of the big question and the original title of the proof question. The second-order differential of Lian Chao class is a guess, which is repeatedly emphasized. "
