Hello Sanket Petkar. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

We have no idea of what exam you are talking about. But, I will tell you one thing.

If they have mentioned in the Documents Required section that they need your self-attested marksheet, then they will not accept any non-attested marksheet of yours. I tell this through the personal experience of one of my cousins.

Hope this helps you and all the best!
