How is GPA Calculated?

Here is  a good description of how GPA is calcualted. So people can compare their local percentages with the gpa of US Education system here. Some universities use a different scaling system. Normally they mention how to convert them to GPA system in transcripts. But most of the students from India get into problems when sending the transcripts since the universities donot accept transcripts send directly by the applicant. In such case i would suggest, get your transcripts signed and sealed on the cover by assistant registrar of registrar or head of your under-graduate section and send them to the university.
