## About

GPA (Grade Point Average) is the standard way to summarize your academic performance. Each course contributes a number of grade points based on the letter grade (or numeric grade, depending on the scale) multiplied by the number of credit hours. The total is then divided by the total credits to give a single number on your chosen scale.

Add a row per course, set the credit hours and grade, and the calculator keeps a running weighted GPA. Switch the scale on the fly — the same grades will produce a different GPA on the 4.0 vs 5.0 vs percentage scale.

## How to use

1. **Pick a scale** — 4.0 (US college), 4.3 (some HS), 5.0 (weighted HS), 10.0, or percentage (US K-12).
2. **Add courses** — Credit hours + grade (letter or numeric, depending on the scale).
3. **Read your GPA** — The weighted GPA updates live as you add, remove, or edit rows.

## Examples

### A typical college semester

Three 3-credit courses: A, B, C.

Input:

```
3 cr A, 3 cr B, 3 cr C
```

Output:

```
GPA: 3.0 (on 4.0 scale)
```

### Honors + standard mix

A 4-credit A and a 1-credit F.

Input:

```
4 cr A, 1 cr F
```

Output:

```
GPA: 3.2 (on 4.0 scale)
```

## FAQ

### What is weighted vs unweighted GPA?

Unweighted GPA is on a single 4.0 scale — every class counts the same. Weighted GPA gives extra points for honors, AP, or IB classes (often a 5.0 scale). This calculator supports both, plus the 4.3 and percentage scales.

### How do I convert a percentage to a 4.0 scale?

Pick the "percentage" scale and enter the percentage (e.g. 95). The tool uses the common US conversion: 90+ = A (4.0), 80-89 = B (3.0), 70-79 = C (2.0), 60-69 = D (1.0), below 60 = F (0.0).

### How is GPA weighted?

Most systems use the credit hours of each course: grade points (4.0 for A, 3.0 for B, etc.) times the credit hours, divided by total credit hours. Some systems use a 4.0 scale, some a 4.3, some a 5.0. The tool lets you pick.
