But the difference is that probability statistics is slightly more difficult than in previous years. The final geometric finale is also more difficult than 20 19 and 2020, basically returning to the level of 20 17 and 20 18.

Although the mathematics test paper of 202 1 has changed, the degree of change is also within the acceptable range. Many changes also mean that the examination method is more flexible, which is a good thing for candidates with better mathematics. This subject can be used to open the gap.

problem analysis

1, solve the problem

2 1 solves most of the same problems as in previous years, such as graphic transformation in lattice diagram, application of solving right triangle, law exploration, circle, statistics, quadratic function synthesis, geometric finale and so on.

Compared with previous years, the difference is that there is one less application problem of equation and one more synthesis problem of linear function and inverse proportional function, and the problem of circle is a little more flexible than previous years, so it is not difficult to solve the application and statistics of right triangle.

Step 2 fill in the blanks

In previous years, the second way to fill in the blanks was to investigate factorization, and the method of solving problems was relatively fixed, which could be solved by "lifting" first and then "fixing". The factorization of 2 1 year disappears completely, and it is replaced by an estimation problem of irrational numbers, but it is not difficult.
