In 2008, the second senior high school entrance examination in mathematics was more difficult than the first one, almost the same as the third one. The difficulty of mathematics in 2008 and 2009 is basically the same. This is the case with Math I, Math II and Math III. By 20 10, the difficulty of math 1 has slightly increased, while the difficulty of math 2 and math 3 has remained stable. As far as the past 20 1 1 year is concerned, the difficulty of Math I, Math II and Math III in 20 1 year is slightly fine-tuned. As can be seen from everyone's average score, the average score of Math I, Math II and Math III in 201/year is higher than that in previous years. It is predicted that compared with previous years, especially compared with 20 1 1, the difficulty of 20 12 may increase, but the overall difficulty is stable and moderate.
