Generally, the calculation cycle of GPA is the period of the highest academic qualification (for example, in the last academic year, fresh graduates should fill in the credit scores of freshmen to juniors).

The gpa algorithm of each school is different. The scores on American university transcripts are generally divided into A as excellent, B as good above average, C as medium level, D as the lowest passing score and F as failing score. A=4，b=3，c=2，d= 1，f=0。 If there is a+sign, add 0.3 points, that is, b+=3.3 points.

GPA scoring method:

There are four grading methods: arithmetic average, weighted average, credit grade point and average credit grade point.

Arithmetic average is to add up the scores of all subjects and divide them by the number of subjects.

The weighted average score is the average score of each course multiplied by the corresponding credits of the subject and then divided by the total credits.

The sum of the credits is the sum of the credits of each course multiplied by the corresponding credits.

The average GPA is the sum of credits in each course multiplied by the corresponding GPA divided by the total credits, that is, the sum of credit GPA divided by the total credits.
