• Add up the SGPA  of both semesters.

which is 4.85+5.02=9.87

• multiply it by 10= 9.87x10=98.7
• subtract 7.5 from it = 98.7-7.5=91.2 which is your final percentage.

use this above mentioned formula in order to calculate the percentage of all the semesters.

Hope this helps.

Hello,

You need to use the formula prescribed by the university or institute in which you are studying. To know the formula to convert the SGPA or CGPA in to percentage you need to enquire in the examination department of the institute. They will provide you the formula to convert your SGPA to percentage. If you do not have any formula then you need to find your CGPA in the marksheet and multiply it with 10 to determine the percentage that you have scored until the second semester.
