How to calculate CGPA for engineering students?
CGPA is defined as Cumulative Grade Points Average. GPA is the measure of average grade points of each semester. Its a average grade point obtained in all the semesters.
Formula for CGPA Calculation
CGPA = Î£ ( Total Grades ) / Total Credits
Total Grades = Î£ ( Grade * Credits )
Step 1: Assume a set of grade points to map with the subjects.
Grade | Grade Points |
A+ | 4.7 |
A | 4 |
B+ | 3.7 |
B | 3 |
C+ | 2.7 |
C | 2 |
D+ | 1.7 |
D | 1 |
Step 2: Lets assume the Grade and Credits for the subjects till the fourth semester.
Semester | Subject | Credits | Grades |
1 | Mechanics | 3 | B+ |
2 | Applied Physics | 4 | A |
3 | Aerodynamics | 2 | B |
4 | C Programming | 1 | D+ |
Step 3: To find the total grade points lets map the grade points of each subject in the given formula.
Total Grades = Î£ (No of Credits x Grade points)
Total grades in Mechanics = 3 x 3.7 = 11.1
Total grades in Applied Physics = 4 x 4 = 16
Total grades in Aerodynamics = 2 x 3 = 6
Total grades in C programming = 1 x 1 = 1
Step 4: Find the total credit by adding the credits of all the subjects.
Total credits = 3 + 4 + 2 + 1 = 10
Total credits = 10
Step 5: Add the total grades of all subjects.
Total grades = 11.1 + 16 + 6 + 1 = 34.1
Total grades = 34.1
Step 6: To find the Cumulative Grade Points Average, substitute the obtained values in the CGPA formula.
CGPA = Î£( Total Grades ) / Total Credits
= 34.1 / 10
CGPA = 3.41
