I have filled wrong State of eligibility in josaa and in 1st round I am eligible for it Delhi mechanical will I get problem in getting admission

I think you shpuld contact in Josaa (By phone or email) , to chage the state of elegiblity. you wil be alloted seat according to your filled state of elegiblity , but when you went to verify your documents, you will face difficulty, so, i think you should rectify this problem.

Hope this helps.
