The previous choice to fill in the blanks is easier than 20 10, but the second question of the big question (19,20) is as difficult as the one called abnormal in 10. If it's not done, it's normal. Most people can't do it. (I have done these two questions for two hours, which is related to my not doing them for more than a year, but it does illustrate the difficulty of abnormal problems. )
Don't worry, few people can do it in the examination room environment. If your goal is not to clear the north, in fact, the problem is not very big, so calm down.
In short, this year's questions are quite reliable, and the difficulty is between 10 and 1 1.
