The COMSATS University Islamabad GPA Calculator is a user-friendly web application designed specifically for CUI students to calculate their semester or cumulative GPA based on the university’s official grading policy.

Core Functionality

1. Course Entry System: Students can input details for each course, including:
   
   • Course name/code
   • Marks obtained (percentage)
   • Credit hours (defaulted to 3, adjustable from 1-6)
2. Automatic Grade Conversion: The system automatically converts percentage marks to the corresponding letter grade and GPA points according to CUI’s official grading scale:
   
   • A (85% and above): 4.00 GPA
   • A- (80-84%): 3.66 GPA
   • B+ (75-79%): 3.33 GPA
   • B (71-74%): 3.00 GPA
   • B- (68-70%): 2.66 GPA
   • C+ (64-67%): 2.33 GPA
   • C (61-63%): 2.00 GPA
   • C- (58-60%): 1.66 GPA
   • D+ (54-57%): 1.33 GPA
   • D (50-53%): 1.00 GPA
   • F (0-49%): 0.00 GPA (Fail)
3. GPA Calculation Method: The calculator computes GPA using the weighted average formula:
   
   • Each course’s GPA points are multiplied by its credit hours
   • These weighted values are summed, then divided by the total credit hours
   • The result is rounded to two decimal places
4. Interactive Features:
   
   • Add multiple courses with the “Add Course” button
   • Calculate final GPA with the “Calculate GPA” button
   • Reset all entries with the “Reset” button
