Hi, yes you can provide the documents as DU is accepting digilocker's documents as valid for giving admissions to students.

Although, your admission will be confirmed but you will have to give an undertaking in a written application to principal that you'll submit your original documents later. After that, they will approve your admission and as soon as you get your original documents from your school, you can submit them in the college.

You can even contact the DU admission helpdesk to confirm about how the process will go about and by when you are expected to submit the original documents.

Good Luck
