• Add all those results
• Divide by the total number of credits attempted

• Subject B (4 credits, A = 8): 4 × 8 = 32
• Subject C (2 credits, O = 10): 2 × 10 = 20
• Total = (27 + 32 + 20) / (3 + 4 + 2) = 79 / 9 = 8.78 CGPA

Understanding GPA vs CGPA

Before diving into calculations, it’s important to understand the difference between GPA (Grade Point Average) and CGPA (Cumulative Grade Point Average)—two terms that are often used interchangeably but serve different purposes. GPA is calculated for a single semester, representing a student's performance during that specific academic term. On the other hand, CGPA is the cumulative average of GPA scores across all semesters, reflecting the overall academic performance throughout the course duration. If you’re analysing performance for one semester, you should use the GPA formula. But for a complete picture of your academic standing whether it’s for job applications, higher education, or scholarship eligibility the CGPA is what you need to calculate and convert.

Number of Subjects and Credits Per Semester

Anna University typically assigns:

• 3 or 4 credits to theory subjects
• 1 or 2 credits to lab/practical courses
• Project work or electives can carry more

Each semester generally includes 6–8 subjects depending on the course.
