Has someone recieved a call from DAV Pitampura for admission in Management seat? Any idea what they are asking for and why this hurry?

Should I wait for first list to come out or get seat blocked right away?

I know once you get it blocked, you can't take money back if you get admission in some other school. But at the same time, they may end up simply dropping you from potential name in first admission list. Please share your inputs.
