# CGPA GGPA or conversion to percentage

In our university, CGPA is defined as the mean of even and odd semester SGPA (SGPA being the pointers in each semester)
And GGPA is defined as the mean of all CGPA's.
That means the CGPAs are provided once per year in the 4 year course and they are the avaerage of the two semesters of one year.
So should I fill in the CGPA of the last two semesters or the GGPA of 4 years in the XAT form?
