In fact, fourth grade mathematics is very easy to learn. As long as you practice more at ordinary times, you can definitely get full marks in the calculation questions. You need to buy an exercise book, such as getting an excellent grade. You can't just do what the teacher arranges. You have time to do more exercise on weekends. You should carefully examine the questions during the exam and have enough time to check them after the exam. This is all my experience. Anyway, I got full marks in math in elementary school. I was a math class representative from grade three to graduation. Finally, be careful, be careful, be careful again! I hope you can get good grades, O(∩_∩)O Thank you.
