git clone https://github.com/yourusername/gwa_calculator.git
cd gwa_calculator
npm install
npm run dev

Access the application:

• Development Server: http://localhost:3000

docker build -t gwa-calculator .
docker run -p 3000:3000 gwa-calculator

Access the application:

• Web Interface: http://localhost:3000

The calculator uses the standard weighted average formula:

For each subject:
  weightedGrade = grade × units

GWA = (sum of all weightedGrade) / (sum of all units)

Example:

• Math: 1.6 (3 units) → weighted = 4.8
• English: 2.0 (3 units) → weighted = 6.0
• GWA = (4.8 + 6.0) / (3 + 3) = 1.80
