Third party GPA evaluation

[Shruti Rai]

Is this necessary for me to do? Which reliable third parties provide this facility?

[Juhi rathod]

You need to get your GPA evaluated by a third party only if the program you're applying to asks for it.
Usually, universities this mention on their program page. They also tell you which third parties you should go to for conversion.
If they haven't mentioned anything, you can check out WES.

It's not necessary.
And if the university is okay with you doing it yourself, you can use the instructions here to convert your scores.
