As a student currently studying in IIT kgp and having cleared jee 2006 all i can say this is that this exercise in changing the pattern is completely pointless. The new pattern we encountered in april was not stress reducing it increased it! The paper was acknowledged to be one of the more difficult jee papers in recent years. Stress comes not from the level of difficulty but the competition in jee. And "reduced dependency on coaching centres " is not going to happen. Bansal had 900+ selections this year. The coaching centres are here to stay whether we like it or not.
