Engineering Entrance Exam

Sorry, but you should be above a particular rank to get into any IIT. And, since you haven't got any rank, you will not be eligible for any IIT college.
Try for other colleges based on JEE Mains.

Preparing for GATE is a good option. It all depends on your interest whether you are willing to pursue BE or B.Sc.

You may contact Sharda University, Chitkara University, GLA University, GNA University, LPU, Amity University for admission on the basis of your low rank and JEE Mains marks.

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.
