What you want to ask is that 47 points in the fifth grade math test is not good? Pity. According to the regulations of the Provincial Education Bureau, the classification criteria of primary school grades are: 90 to 100 is excellent at grade A, 70 to 89 is good at grade B, 60 to 70 is grade C, and below 60 is grade D.. A score of 47 in the fifth grade math exam is a poor D grade.
