7 years back, while preparing for IIT-JEE, I felt the best ever paper for the JEE entrance was in 93. That paper tested understanding of concepts, analytical ability, speed and most important patience. Exams like that differentiate the scientists from the engineers. The current pattern is good if you want to churn out scores of software engineers but, for research I guess, the 90's exam papers were much better. India lacks in pure sciences and this pattern is not helping the situation in any way.
