I am amazed by the handling of the incident by CBSE. It was quite remarkable that CBSE had thought of this possibility and had a full back up in terms of duplicate exam material which was already stored in each city where there was a center for the exam, and this material could be distributed to most of the centers within a couple of hours.
(Contrast this with JEE paper leak in 1997, which, co-incidentally also happened in Lucknow. We had to postpone admission by 5 weeks, causing havoc to admissions in all other engineering colleges in the country, since most students who get admission to IITs, will leave their other college, causing vacancies there. There was no plan B.)
Unfortunately, there was AFMC exam in the afternoon, and thousands of students were scheduled to give both. Worse, some schools were centers for both AIEEE and AFMC exam, and therefore, could not re-conduct AIEEE after 3 hours. CBSE lost no time in giving relief to all affected students. They announced that those who had to give AFMC or those whose center cannot conduct a late AIEEE exam will be able to give AIEEE on 8th May. Taking such quick decisions must be applauded. Of course, the problem did not end here. Some students complained that they had both AFMC on 1st afternoon, and another exam on 8th. CBSE again came to their rescue and said that they will be able to give exam on 10th May.
What this means is that CBSE was ready with not just one extra set of examination material, but is also ready with multiple sets of question papers. That is excellent planning. So despite a major problem on hand, CBSE will stick to its timeline for announcing results.
When 11 lakh students are told that they have to stop writing an exam, and give a different exam a couple of hours later, this is bound to cause problems. Chaos is bound to happen. But the fact that more than 10 lakh students could give the exam the same day is something that speaks volumes about how AIEEE is planned (as opposed to JEE where we take double the time to announce the result for less than half the number of candidates, with no transparency).
And now an interesting outcome of this. Since the students would have given several different exams (the question paper on 1st, 8th, and 10th, and the online version would be different), there would be some way to compare the performances of the students across those exams. And if the exam can be held on 1st, 8th, and 10th May,
why can't it be held on 1st December, 1st January and 1st May (just giving three random dates to make a point that it is possible to organize the exam on multiple dates through out the year - and may even allow students to sit for 2 of those exams - something that I have been arguing for in many of my posts).
Added on 3rd May: CBSE has announced that the exam will be held on 11th May for all those who could not give the exam on 1st May. So, it will not be on 8th and 10th, but only on 11th.
