Dear Aaditya,
There is a good news for you, If you go by the information given at DU LLB Cutoff 2018 you would come to know that all the candidates of PwD and CW categories were offered an LLB seat who took part in DU LLB 2017 entrance. Going by that you need not to worry about the prospects that whether you'll be able to take admission in Faculty of Law, DU or not. Be sure that you are going to FoL for doing your LLB programme. Best of Luck!
