A Dartmouth GPA (Grade Point Average) Calculator helps students at Dartmouth College estimate their GPA based on the grades they have received in their courses. This tool is essential for students who want to track their academic performance and set goals for improvement. Here, we will explain the formula, inputs, and calculations involved in the Dartmouth GPA Calculator.
Formula
The GPA is calculated using the following formula:GPA=∑(Grade Points×Credit Hours)∑Credit Hours\text{GPA} = \frac{\sum (\text{Grade Points} \times \text{Credit Hours})}{\sum \text{Credit Hours}}GPA=∑Credit Hours∑(Grade Points×Credit Hours)
Inputs
- Course Name: The name of the course.
- Grade: The letter grade received in the course (e.g., A, B+, C-).
- Credit Hours: The number of credit hours the course is worth.
Grade Points
At Dartmouth College, grades are typically assigned the following grade points:
- 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: 1.0
- E (Fail): 0.0
Calculations
To calculate the GPA, follow these steps:
- Convert Grades to Grade Points: Use the grade points table to convert each letter grade to its corresponding grade points.
- Multiply Grade Points by Credit Hours: For each course, multiply the grade points by the credit hours to get the quality points.
- Sum Quality Points and Credit Hours: Add up all the quality points and all the credit hours.
- Divide Quality Points by Credit Hours: Divide the total quality points by the total credit hours to get the GPA.
Step-by-Step Example
Inputs:
- Course 1:
- Course Name: Math 101
- Grade: A
- Credit Hours: 3
- Course 2:
- Course Name: History 201
- Grade: B+
- Credit Hours: 4
- Course 3:
- Course Name: Chemistry 301
- Grade: C
- Credit Hours: 3
Conversion of Grades to Grade Points:
- Math 101: A = 4.0
- History 201: B+ = 3.3
- Chemistry 301: C = 2.0
Quality Points Calculation:
- Math 101: 4.0 (Grade Points) × 3 (Credit Hours) = 12
- History 201: 3.3 (Grade Points) × 4 (Credit Hours) = 13.2
- Chemistry 301: 2.0 (Grade Points) × 3 (Credit Hours) = 6
Total Quality Points and Credit Hours:
- Total Quality Points = 12 + 13.2 + 6 = 31.2
- Total Credit Hours = 3 + 4 + 3 = 10
GPA Calculation:
GPA=31.210=3.12\text{GPA} = \frac{31.2}{10} = 3.12GPA=1031.2=3.12
Relevant Information Table
| Course Name | Grade | Grade Points | Credit Hours | Quality Points |
|---|---|---|---|---|
| Math 101 | A | 4.0 | 3 | 4.0 × 3 = 12 |
| History 201 | B+ | 3.3 | 4 | 3.3 × 4 = 13.2 |
| Chemistry 301 | C | 2.0 | 3 | 2.0 × 3 = 6 |
| Total | 10 | 31.2 |
