Grade Point Average (GPA) Calculator Project Overview

This mini-project, titled Grade Point Average (GPA) Calculator, is a web application designed to help students easily calculate their GPA. It is developed using PHP and SQLite and provides an automated platform for GPA calculation. The project features a simple and intuitive user interface built with Bootstrap Framework and includes several useful functionalities for students.

How the Grade Point Average (GPA) Calculator Works:

The GPA Calculator is an easy-to-use web application that allows students to calculate their GPA for each semester. The application lets users manage the Grade Table, which defines the grade scale (e.g., 4.0) and corresponding letter grades (e.g., A+). Users can update the grade table by entering the grade letter, grade percentage range, and grade scale. While the application calculates the GPA, it does not store student records in a database. However, users can print the results to keep a record.
