Hello, I hope you are doing well

If you are talking about books then they used to be delivered at the address which you filled in your application form, but that was too much time consuming and still there was no guarantee that you will get the material for entire syllabus.

So, what you should do is wait for an SMS in which you will receive details about when and where you should go to collect your books. After that you have to go there with your DU SOL ID Card, Fee Slip and some other documents which will be mentioned in the SMS(even if not mentioned you must try to carry all of the documents which you uploaded while filling the application form). After the Document verification is done you will get your books.

Hope this helps.
