Cr@cku is bluffing
So cr@cku claims that 50k have checked their responses which is improbable because 1.4 Lakh registered for the exam let's assume 1.2 L attended the exam. How is it possible that >40% of applicants have already submitted their response sheet on cr@cku's website within few hours?
They are definitely double counting the responses of people who submitted their responses 2 days ago which is why percentiles are low. They should not have created this mess in the first place by releasing their unofficial answer key.
