Follow the below mentioned steps to calculate the CGPA:
Determine the total number of credit hours you have attempted. For example, after two semesters you might have attempted 24 credit hours. This figure can be found on an official transcript from your school.
Determine the total number of grade points you have earned. For example, you might have earned 72 grade points in two semesters. As with the number of credit hours attempted, this figure can be found on your school transcript.
Enter the number of grade points earned and credit hours attempted into the CGPA formula: Grade points earned divided by credit hours attempted equals cumulative grade point average. Using the example figures, this would be: 72 grade points earned divided by 24 credit hours attempted equals cumulative grade point average.
Apply the CGPA formula using the figures you have entered to calculate your CGPA. With the example figures, the CGPA is 3.0.
The CGPA calculation tool provided here was designed to help you forecast your average and plan its progress. Calculations are strictly for information purposes. The responsibility for obtaining satisfactory grades in each of your courses and thus maintaining the required GPA is entirely yours. We encourage you to also use this tool to determine your eligibility for scholarships and bursaries and for graduate programs, or to chart a course for achieving your personal goals.
Here we have the formula as well:
(OF NUMBER OF CREDITS OF THE ith course of the
nth semester and grade points of the ith course of the nth semester) /summation (summation) number of credits of the ith course of the n th semester
What is GPA?
GPA is the ratio of the sum of the products of the number of credits of courses registered and the grade points corresponding to the grades scored in those courses, taken for all the courses, to the sum of the number of credits of all the courses in the semester.
CGPA will be calculated in a similar manner, considering all the courses enrolled from first semester
The CGPA does not form part of the student record for the Faculty of Medicine and most graduate studies programs.
