1, Optimization Training of Experimental Class, synchronous textbook optimization, covering the training of PEP and basic knowledge of mathematics, thinking expansion and application ability. In mathematics, we pay attention to foundation consolidation and thinking expansion, especially the cultivation of application ability.

2. From the topic type, exploration and improvement is a high-level topic, and there are practice classes every two or three chapters to consolidate the previous knowledge. There are real questions at the end of each unit, so that children can know what they have learned in advance, and the final exam is handy. Behind each unit, there is room for thinking about Olympiad Mathematics, which increases the synchronous Olympiad Mathematics questions and allows children to contact a wider range of mathematics fields. The unit independent evaluation paper allows children to check for leaks and fill gaps. At the end of the period, there is also an answer analysis and a strategy for learning hegemony.
