What is cumlative grade point average?

Cumulative Grade Point Average (CGPA) is a weighted average of all your grades earned in all the courses you've taken throughout your academic career (high school, college, etc.) up to a specific point in time. It represents your overall academic performance. The weighting comes from the credit hours or units assigned to each course; a higher-credit course has a greater influence on your CGPA than a lower-credit course.
