First of all, I'd like to begin by saying I'm not writing any of this as a representative or supporter of the institute, nor am I humiliating anyone.
I just want to say that if you believe you are being betrayed, and like someone pointed out, giving 7-8 attempts and still not figuring a way to clear it, the most logical thing would be to retrieve your answer sheet. Instead of going at the exam 7-8 times the same way, why not spend once- or better yet, why not pool money and ask for the answer sheet of a single person and see how they have graded the paper? This way you all contribute 500rs for a single answer sheet, which gets uploaded here, and the 100s of people who find themselves betrayed can actually see how marks are awarded, and if or not marks are awarded blindly..
Not checking your answer sheet even once and attempting the same way 7-8 times is like knocking 7-8 hours on the same door without even realising or knowing if someone lives inside or if the door's locked or not.
One of us should spend rs 500 for the sake of the whole community, and let the others see how things actually work. If after that, you are not convinced, RTI and PMO are always there.
