“Pagalguy.com”- often have I wondered, what the creator of this website had in mind while selecting this name as the domain name for an MBA preparation networking site. Of late, however, I have realized the major chunk of the website users seem to be some of the most “pagal” people that one would come across ( I literally mean that ). Friends, forgive my misdemeanor but the line of thought behind this assertion, though selfish, is very simple. “Most of the website users after attempting their exam, post their exam experiences and the questions in their slots on the website. Thereby, albeit to a limited extent, they make the exam easier for the future exam takers, which in turn leads to higher cutoffs, directly affecting those who gave away free advice in the first place”. What must one call these people if not 'dumb'?
If we come down to deliberating this issue, the more enlightened ones among us would definitely counter with 'noble' perspectives. “Isn't, that unselfish help to our beloved countrymen?” or perhaps “What's the harm in doing something good for others”? Well, there is! Not only do these people raise the cutoffs for themselves but also those who cannot avail of the 'merits' of social networking because they are not as privileged as others. Thus not only do these people create an imbalance in the quantum of exam pressure and difficulty perceived by candidates, they also severely undermine the basic idea and spirit of the exam conducting body. One of the foremost goals of the exam conductors and question makers is to create pressure and an environment of stress in order to accurately judge how the student would perform under difficult conditions. This tendency, they have repeatedly shown, by altering exam patterns at the last minute , reducing time , making you uncomfortable in terms of the stationary and equipment available and more often by intimidating you with complex language in questions.
You must direct your attention towards this simple fact, to which all of us would humbly submit to without a speck of doubt. 'Disclosing exam patterns and questions on social web space, though may seem as a mark of our increasing social freedom or more generally, a tool that enhances your performance, unjustly imbalances the burden of exam pressure and distorts the cutoff levels. Let us endeavour to succeed in all exams we take by not being unfair to others. All the best for your exams.
