The overall difficulty is moderate. Fill in the blanks is slightly more difficult than 20 14, but the overall difficulty is not high. 12 and 16 may be a bit difficult.

Most of the problems are simpler than 20 14, and the difficulty of conic curve is obviously reduced, which is a very basic problem. Choosing some of the three and returning to the most basic things is obviously less difficult than 20 14. The only slightly more difficult is the statistical regression linear equation of 19, which is slightly more difficult, mainly because of the nonlinear relationship, so it is not easy to write for the time being.

17 and 18 belong to the normal difficulty range, but the lateral area calculation of 18 solid geometry is a bit troublesome and takes a lot of time.

In essence, the difficulty of the college entrance examination questions is almost the same as usual, mainly because you will be nervous and your brain will be short-circuited, so your score may not be higher than usual.
