i secured 550 marks in neet can i get government seats through defence quota in delhi university??..

Hello aspirant,
I hope you are doing well and good. As you mentioned in question that you have advantage of defence quota so you have great chance of getting admission in Delhi University in the marks that you're expected. Remember one thing that you have very less chance you have to apply for the counselling to get admission in DU.
Otherwise below a link with the hell of this you can predict any other colleges.
