On the basis of internal experiments, in response to the call of "reducing the burden" of the country, we made every effort to create a set of "one-stop" special training papers and realized the concept of "one book is worth four". There is a "test paper description" at the beginning of the test paper. The weekly exercises are innovative, and the knowledge points and typical examples are carefully refined for convenient and flexible use. The quality of unit, monthly examination and mid-term and final examination questions is good, the inspection is comprehensive, and the study and examination are connected.
