Ordinary algorithm: above 90 points can be regarded as 4, above 80 points as 3, above 70 points as 2, 1.

Standard algorithm: the weighted average is divided by one hundred and multiplied by four.

Extended data:

The accuracy of GPA often reaches 1 to 2 digits after the decimal point, such as 3.3 and 3.75. The standard calculation method of GPA is to multiply the weighted average of college grades by 4 and then divide it by 100.

The two most commonly used algorithms for domestic students are standard algorithm and common algorithm, and the specific formulas are as follows:

GPA standard algorithm formula: GPA = [(92× 4+80× 3+98× 2+70× 6+89× 3 )× 4]/[(4+3+2+6+3 )×100] = 3.3100.

Common GPA algorithm: GPA = (4× 4+3× 3+2× 4+6× 2+3× 3)/(4+3+2+6+3) = 3.00.

In addition, the following algorithm can be used to convert the percentage system of domestic universities into GPA of 4.0:

Master the formula of grade conversion. Let X stand for the grade of percentile system, then when GPA is 4.0, the conversion formula of grade is (x/20)- 1=GPA.
