美国申请读研使用的是中国本科官方的GPA还是标准算法的GPA呢？

美国的GPA等级：

A 4.0
A- 3.7
B+ 3,.3
B 3.0
B- 2.7
C+ 2.3

C 2.0
C- 1.7
D+ 1.3
D 1.0
D- 0.7
E 0.0

我给你发的是美国大学的算法，是英文的，你既然打算去美国读研，相信你应该看得懂。

The Calculation
First add up the total hours attempted and grade points earned...
For Example:

Credit Hours
Grade
Grade Points

4 hours X A (4.0) = 16.0
3 hours X B+ (3.3) = 9.9
5 hours X C (2.0) = 10.0
12 hours 35.9
Then divide the total grade points by the overall hours
35.9/12 = 2.99 GPA

The formulas:
GPA X Hours = Grade Points
Grade Points / Attempted Hours = GPA

To Add or Subtract Grades:
1. First you need to get your Transcript Totals. This is available online when you access your Student Academic Transcript.

2. Then add or subtract hours and grade points you are considering and then re-divide using the calculation:
Note: You must use GPA Hours not Attempted Hours
GPA Hours includes "E’s", but does not include CLEP, CR/NC, Transfer, etc.

Examples:

If I got all "B’s" this semester (12 hours), what would happen to my GPA?
Add in: 3.00 x 12 hours = 36 grade points

Refigure: 99.799 54.66
+36.000 +12.00
135.799 66.66

135.799 grade points/66.66 hours = 2.037 cum GPA

If I repeated 8 hours on "D’s" this semester, and earned all "B’s", what would happen?
Subtract out: 1.00 X 8 hours = 8 grade points
then add in 3.00 X 8 hours = 24 points

Refigure: 99.799 54.66
-8.000 - 8.00
+24.000 +8.00
115.799 54.66

115.799 grade points/54.66 hours = 2.119 cum GPA

If I repeated a 5 hour "E" and a 5 hour "D-" this semester, and earned all "B’s", what would happen?
Subtract out: 0.00 X 5 hours = 0 grade points & 0.7 X 5 hours = 3.5 grade points then add in 3.00 X 10 hours = 30 points

Refigure: 99.799 54.66
-3.500 -10.00
+30.000 +10.00

126.299 grade points/54.66 hours = 2.311 cum GPA

4分制，标准算法和常见算法均可
