According to my feeling, yes.

First, you should read all the books on basic knowledge, especially some small print test sites, some corners of Dongdong, and the margin ratio of gold and rubber, and the ratio of ups and downs, and you should also be aware of those.

Second, pay attention to books. I think problem sets are very important. After reading the book once or twice, I went to do the problem and recite the problem set. Later, when I took the exam, I found that there were not many things in the problem set, but there were also exams. Books are primary and problem sets are secondary.

Third, you should be proficient in arithmetic problems, because the final comprehensive problem is arithmetic problems. You should know what the rights and interests are, and calculate them quickly, otherwise you will spend a lot of time there and get higher scores in arithmetic problems. Don't stay too long in the previous choices, one is only 0.5 points, which is not worth spending so much time.

I wish you pass the customs next time.
