Hello Mohan,

First let me know what was there on the first page of the question paper? If there was your Roll No. or Registration No. then AIBE requires only your registration information In that case you can attach your Admit Card Copy.

If it was anything else except Roll No. & registration No. in this case I would suggest you to write an Application to AIBE to mention your issue, Only they can help you regarding.

Good Luck!

You can download all sets of questions papers of AiBE XI from link and send the authorities regarding all your details and application nunber via email so they can retrieve your details.
