As the saying goes, it is not difficult to be in trouble. There is no specific definition of difficulty. Of course, I am also a candidate this year. I got 14 1 for the first volume. The overall feeling of the test paper is as follows: most people can work out 13 before filling in the blanks, and 14 can be worked out by death, but it is time-consuming. 15, 16 is simple. 17 and 18 are computationally intensive. The second question of 19 is a bit difficult to think about, but it can almost be done. 20 questions are too abnormal, with a lot of calculation and thinking.
Overall impression: Compared with 13, it is slightly more difficult, so it should be no problem to take the test of 128.
