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. It has a large amount of calculation and outstanding comprehensiveness.
Li Lin's four sets of papers not only increase the comprehensiveness of the topic, but also make it impossible for candidates to quickly build a context for solving problems in their brains. They can only cross the river by touching the known stones. 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.
