Let's just say you weren't careful! Mathematics in the first grade is the simplest, and some teachers will mention a lot of elementary school knowledge. So it's incredible to get 58 points. In view of your situation, I suggest you buy a document to do it. Let's just say that when I was in junior high school, my class didn't score below 80 in math. There were three problems in one semester, the school issued two, and the teacher asked me to buy one. It is strange that you can't practice more than 95 in a semester. Of course, when you do the problem, don't look at the answer. No, ask the teacher more questions, and then check the answers after you finish, so as to give full play to the role of the information.
