Accurately speaking, GPA and average score cannot be directly converted, because it is inevitable that several courses will not be counted as GPA each semester, and there will be incentive credits to interfere with the calculation. In terms of the conversion between subject grades and GPA, the calculation formula is: (score -50)/ 10= GPA, that is, 100 GPA is 5, and 67GPA is 1.7. The GPA of a four-year university is higher than 1.7, which is the minimum standard for us to get a degree certificate.
