GPA Calculation & Standard Rounding
Dartmouth calculates GPA to 14 decimal points within Banner and follows standard rounding to two decimal places.
GPA Calculation
The basic GPA calculation is as follows:
(Quality points÷GPA Hours)÷3
Quality points come from the grades:
A = 12 quality points
A- = 11 quality points
B+ = 10 quality points
B = 9 quality points
B- = 8 quality points
C+ = 7 quality points
C = 6 quality points
C- = 5 quality points
D = 3 quality points
E = 0 quality points
GPA Hours translate to courses taken, so 1 course = 1 GPA Hour.
| Example for a cumulative GPA | Example for a term GPA |
|---|---|
| Quality points: 255, GPA Hours: 30 | Quality points: 30, GPA Hours: 3 |
| The calculation is 255/30 = 8.5 | The calculation is 30/3 = 10 |
| 8.5/3 = 2.83333333333333 | 10/3 = 3.33333333333333 |
| GPA = 2.83 | GPA = 3.33 |
Quality points: 255, GPA Hours: 30
Quality points: 30, GPA Hours: 3
The calculation is 255/30 = 8.5
The calculation is 30/3 = 10
8.5/3 = 2.83333333333333
10/3 = 3.33333333333333
GPA = 2.83
GPA = 3.33
Standard Rounding
Standard Rounding means that only the number to the right of the final decimal place is used to round.
Examples:
- (345/31)/3 = 3.7096773 => 3.71
- (345/32)/3 = 3.59375 => 3.59
- (345/33)/3 = 3.4848483 => 3.4 (Note this example in particular)
