Add the marks obtained in all theory and practical courses
Add the maximum marks of all theory and practical courses
Divide total obtained marks by total maximum marks
Multiply the result by 100
Use only the marks that are counted in the final result
If grade points are given, convert them to marks only if your program requires it
Exclude assignments separately only if IGNOU has already included them in the final course marks
Use the final marksheet or grade card for the official percentage calculation
Percentage = (Total Marks Obtained ÷ Total Maximum Marks) × 100
