You may be under too much pressure now, because you are facing the senior high school entrance examination, your math is not very good and your mental state is not good. I suggest you choose some sports or healthy entertainment with your classmates or friends, relax and communicate with friends more. Children your age are not necessarily willing to communicate with their elders or teachers, so choose friends around you! In study, don't be eager for success, especially in math. Be familiar with the questions carefully and know one or two ways to solve problems every day, then your senior high school entrance examination will be fine.
