# GPA Calculator

- **URL:** https://codeasystem.com/calculators/education/gpa-calculator/
- **Category:** education
- **Description:** Compute your weighted GPA on the 4.0 scale from up to six letter-graded courses and their credit hours.
- **Primary output:** GPA (4.0 scale): 3.61

## Inputs
- Course 1 grade (name: `grade1`, type: select)
- Course 1 credits (name: `credit1`, type: number, example: 3)
- Course 2 grade (name: `grade2`, type: select)
- Course 2 credits (name: `credit2`, type: number, example: 3)
- Course 3 grade (name: `grade3`, type: select)
- Course 3 credits (name: `credit3`, type: number, example: 3)
- Course 4 grade (name: `grade4`, type: select)
- Course 4 credits (name: `credit4`, type: number, example: 3)
- Course 5 grade (name: `grade5`, type: select)
- Course 5 credits (name: `credit5`, type: number, example: 3)
- Course 6 grade (name: `grade6`, type: select)
- Course 6 credits (name: `credit6`, type: number, example: 3)

## Outputs
- GPA (4.0 scale): 3.61
- Course 1: A × 4 credits: 16
- Course 2: A- × 3 credits: 11.1
- Course 3: B × 3 credits: 9
- Total credits: 10
- Total quality points: 36.1

## Formula / methodology
```
GPA = Σ(grade points × credits) ÷ Σ(credits)
A=4.0  A−=3.7  B+=3.3  B=3.0 … F=0.0
```

Every letter maps to grade points on the standard 4.0 scale. Multiplying by credit hours gives quality points per course; dividing their sum by total credits yields the weighted GPA that registrars report; a 4-credit A outweighs a 1-credit A exactly four times over.

## Assumptions & limitations
- Uses the plain 4.0 scale without plus/minus inflation beyond the listed values.
- Courses left as “not taken” are excluded entirely.
- Pass/fail and transfer-excluded courses should be omitted.

## How to use
1. **Pick each letter grade**; Set unused course slots to “not taken”.
2. **Add the credit hours**; Copy them straight from your transcript; labs often carry fewer credits than lectures.
3. **Read the weighted GPA**; The result matches what your registrar computes, plus per-course quality points.

## Example
Earning an A in a 4-credit course, an A− in a 3-credit course and a B in another 3-credit course produces a 3.61 GPA.

Result for these inputs:

```
GPA (4.0 scale): 3.61
```

## About this calculator
### Credits make grades unequal

An A in a 1-credit seminar cannot rescue a C in a 4-credit core course: the A contributes 4 quality points while the C drags 8. Weighted GPA exists precisely because courses are not created equal.

### Plus/minus policies vary

This tool uses the common A=4.0 through F=0.0 mapping including minus grades. Some schools award 4.3 for an A+ or omit minus grades entirely; check your catalog if precision matters for scholarships.

### Small courses, big swings

With few total credits, one grade moves the average sharply: a single 3-credit B among 12 credits costs 0.25 GPA points. Early semesters deserve disproportionate attention.

## FAQs
### How is this different from weighted high-school GPA?

Honors/AP “weighted” GPAs add bonus points above 4.0 (e.g. A=5.0). This calculator uses the standard unweighted college scale.

### What happens to courses marked “not taken”?

They are skipped completely; neither their credits nor grade points enter either sum.

### Can I include more than six courses?

Batch them: compute each semester separately, then combine semester GPAs using each semester’s credit totals as weights.

### Do withdrawals affect GPA?

Usually not; W grades carry no grade points. Exclude withdrawn courses here just like untaken slots.
