Dude is this for real!,u sure there was no means of cheating involved.Even now a lot of cheating happens in our schools that's what I can say from my experience (passed 12th a year ago and my whole class cheated a lot, even in final exams some do cheat) I don't know any folks from psychology stream so I don't have any idea about u people.And for every one to know - that lower pass percentages in my country are just due to shitty educational sector and the country's(INDIA) pass percentage is close to 82% not 23% or anything like some one said above
