While I sympathise with those who are affected by the limitation in the number of attempts, I take up the case of SC/ST students.
The number of attempts, under the new format, will be the same for both general and reserved category students. Such equitable treatment is really inequitable, in the sense, in all Entrance and Competitive Exams, the two categories are not treated on par. The latter gets at least a chance more. We dont go into the 'whys' of this here; but only note that IIT-JEE ploughs a lonely furrow, clearly dodging the existing rules of the MHRD.
If general category students get two chances, the SC/ST students may get at least three, if not more.
As of now, the intake of SC/STs in IITs every year is just below 50% of the total quota with more number of attemtps. Now, how will the IITs fill up the quota after restricting the number of attempts and treating them at par with others? The intake will go down further.
For IITs, the right hand does not know what its left hand is doing!
Perhaps, they will wake up when the IITs will be left with nil students from the reserved categories!!
