According to the inquiry, I know that the master of mathematics and the experimental class are teaching AIDS for synchronous practice of primary school mathematics textbooks, with different difficulties, as follows:

Learning to be a master of mathematics is a set of difficult teaching AIDS with many and varied questions, which is suitable for students with excellent academic performance and certain mathematical thinking ability and interest. Many problems in the hegemony of mathematics learning have reached the level of simple understanding, which requires students to have strong logical reasoning and innovative problem-solving ability.

The experimental class is a set of teaching AIDS with moderate difficulty. The number and difficulty of questions are lower than those of mathematics masters, and it is suitable for students with stable grades and certain mathematical foundation and potential. There are also some high-altitude problems and competition space problems in the experimental class, but they are not as many and difficult as mathematics.

To sum up, mathematics is more difficult to master than experimental classes, but it can also train students' mathematical thinking ability and problem-solving ability. If you want to choose a suitable teaching assistant, you can decide according to your child's actual situation and needs.
