Whatever... go for IIT-K. And Metallurical & Material Sc. - great future prospects. Couple of Metallurgical guys whom I know are doing MS-PhD from Stanford. All reasearch on material required for computer chips or microprocessors needs Metallurgical scientists. As far as it's about brand name of IIT-K... words are not needed. But make sure that your kid wants to go for research. Else if he wants to join Software herd, let him go for IIIT or BITS, frankly... in software industry it does not matter, from where did you earn your bachelors :D
