i think that the addition of iit colleges will surely add to the growing power of india. there are many students in india who inspite of being very intelligent do not end up cracking the iit exam. asd a result they get demoralised.Who knows may be such people would have helped india in the long run.there is no doubt that iit is a prestigious institute and it should always be the most important institute in india.But keeping in view the population and the intelligency present in india even 12 institutes seem to be less.Therefore in my opnion we do need more iits so that india can exploit the brilliant minds that is present and scattered all over the country.
