Listen carefully in class, review well after class, do more test questions, preview the courses you haven't learned, and test whether you can make the questions you haven't learned after preview. If you can, the foundation is already very solid. If not, we should strengthen the preview. I am also a middle school student who has just entered junior high school. Since adopting this method, my math scores have been in the top two in my class. I hope my math learning method can help you learn math in Grade One.
