Ground Class
The thing is that, all this new places are advertising by claiming high pass rates whereas no one can confirm how much genuine these information are, in other words the information is not transparent, one thing for sure i know that overall DGCA pass rate being around 20% or so, its not possible that all the ground class places have high pass rates, most of them are definitely faking it. I would suggest a student to check such information and find out who is actually creating the good results and then join.
