Sure you must have been a real dumb student in M. Tech. That is why probably you were ragged so hard that even after 30 years you still crib about ragging. Also if you have so much problem with IIT, you could have left IIT. Instead you preferred to complete post graduation from there, get a nice job worked for 30 years an now probably you got some self confidence so you hid behind your computer and criticize an institute which at the first place was never made for a moron like you.
