Keep up. 80 points in the fourth grade math test can keep up, because the perfect score in primary school math is 100, and the children's 80 points are not very bad. It is said that this achievement is above average. Children's math scores can be improved by timely checking for leaks and filling gaps, supplementing their shortcomings, patiently teaching children or providing corresponding counseling by professional teachers. There are still two academic years to improve the fourth grade of primary school. Don't worry.
