AS per my view increasing the number of IIT will not benifit.So The idea of Makeing more IIT will not work.As Already REC's shifted to NIT's then what is the fun just changing the name of the Institution to IIT.If u really bothered to create more Technical people then Improve the Infrastructure of the existing Colleges.And Increase the education standard by reviseing the syllabus and providing Good Laboratory facilities.Thats it.
