Hello Mate......

As you are of outside delhi so Different colleges participating in JAC have different rules regarding Fee Concession. I have tried to list some of them below:

1. DTU: It has a lot of scholarship programs under various Govt. Schemes. Refer to the link: Scholarships | Delhi Technological University (http://dtu.ac.in/Web/Academics/scholarship.php)
2. NSUT: Are there any scholarships or fee waivers in DTU or NSIT?
3. IGDTUW: https://www.igdtuw.ac.in/index.php?option=com_content&view=article&id=305&Itemid=200

Hope that helps!
