Academic grading in Vietnam

In practice, most U.S. universities used a standardized acceptance of A, B, C, D's only. Thus any A+'s, B+, C+ will be down-convert to A, B, C respectively.

Standardized Table to Convert University GPAs

Some universities in Vietnam employ a system of standardized credit hours, which can translate directly over to the U.S. system. Some instead simply note class hours of 15, 30, 45, 60 ... etc., in an arrangement which needs to be converted into credit hours by dividing class hours by 15. Thus a 15-hour class is equivalent to 1 credit hours, a 45-hour class is equivalent to 3 credit hours.

Most universities convert GPAs class by class. Each class is evaluated for credit hour equivalency. Each class grade point is evaluated according to the native Vietnamese system, converted to A, B, C, D, F, and the individual class grade is translated to the 4.0 system. Then, one must multiply each class grade point by the number of credit hours for the respective class. Finally, the points are totalled up, and divided by the total number credit hours, to arrive at the final GPA.

High schools seem to use a slightly modified GPA system, with higher criteria to receive the equivalent grading letter scale. High school classes are standardized in most Vietnamese public schools, with the respective classes and Grade Point tables listed below.
