I am from India, and if you require any clarification, please feel free to PM me.
There is no good conversion from Indian percentage to American GPA, because the grading and difficulty varies from board to board and school to school
WES is fairly dependable.
Some schools may require you to use 3rd party organization to translate your transcript, so ask colleges before you apply.
Ty Paul. If WES is fairly dependable then my GPA should jump to 3.7 to 3.9
