I am a student from IIT (India). Our grading system is on a scale of 10. According to Baruch's recommended converstion method A=4, B=3.. so C=2 and D=1, while if I convert using ratios our B=3.2, C=2.4 and D=1.6 (its a lot of difference!).. another issue: am I expected to convert each individual grades and then find out the converted cumulative GPA?
