Hello dear..

I cudnt resist myself from sharing my answer on this with you as I faced this reserved seat thing in IP when I was to take admission in MBA course.

So here it is,

The last schooling or graduation you have done from Delhi or outside Delhi will put you into the 85% & 15% category respectively.

I personally feel it a little biased take as I being a resident of Delhi since birth cudnt make it to the university school of management studies even after having a rank better then most Delhi graduates.

Though right now , I have completed my course almost from the same school after scoring a higher rank in next attempt.

Hope it helps. Thanks 

Best of luck .

basical the seat are for those who are the residence of delhi . so teh priority will be given to delhipeople first than outside delhi. all the best have agreat future ahead.
