Hi dear,

Hope you are doing well!

Now let's go through your question.

As you will be knowing that IP take admission on the basis of Delhi(85%) & Outside Delhi (15%). And even future Dephi quota is categorized further into Gen,OBC,SC,St so on.

SCGND means DSC i.e. Delhi SC &

SCGNO means ODSC i.e. Outside Delhi SC

Similarly, for ST there is STGND & STGNO

For General GNGND, GNGNO & GNGNA(All India)

For Defence there's GNDCD/GNDCO

Thank You & All the best!
