There are some advantages to brushing the questions, but just brushing the questions is not very beneficial. The key is whether you understand the topic or not. I think, well, as long as you listen carefully in class and do a few more questions after class to understand, there will be a few percent difference. For example, I only got more than 60 points in the first monthly math exam last semester in Grade Two, and then I began to listen carefully, and I read 1 18 at the end of the semester.
