Hello , 

as your query is you forgot to download the IPU result and now you want to know that what you can do at the time of document verification. 

I want to tell you that there is nothing to worry about there are few sites still available where you can download your IPU results till now and even if you don't find those sides now the other option is that you can go to the counselling cell and let them know your issue they must have the the result of your corresponding to your roll number and for that sake you must have your admit card for at least your roll number otherwise in any of the ways things are not going to be beneficial for you and if you have your admit card for your roll number with yourself then they can generate your result because they may have that in their backup. 

Thank you.
