Solving the Student Grading Headache 🎓

As a Software Engineering student, I realized that tracking specific grades and calculating CGPA across different semesters was a hassle. Spreadsheets are boring, and manual calculation is prone to errors.

So, I built AcademiaTrack— a web-based solution to solve

🛠️ The Tech Stack
I wanted the app to be fast, responsive, and persistent (so data isn't lost on refresh).
• Frontend: HTML5, CSS3, JavaScript
• Styling: Tailwind CSS (for that modern, clean UI)
• Backend/Database: Firebase (to store user scores securely)

🚀 Key Features

Real-time Calculation: The logic updates your CGPA instantly as you input grades.
Data Persistence: Thanks to Firebase, students can log out and come back to their saved data.
Responsive Design: It works perfectly on mobile phones, which is where most students check their results.

💻 The Code
One of the biggest challenges was handling the weighting system for different courses. I used JavaScript array methods to map through the input fields and calculate the weighted average dynamically.
