Siddhartha, if you are looking for a low fee, better would be you try for admission in good private universities like LPU, Chitkara, MIT, etc. where your son can also get good scholarships in various categories. Thus, good education becoming affordable.
It is not just the scholarship but also the placements that are good. If we talk of LPU it is one of the best universities which has best placements in North India. Its alumni are working in reputed companies like Google, Yahoo, etc.
Best wishes for your son.
