Need help

I passed my pe 2 grup 1 in may 2008

and grup 2 in nov 2008.

problm is that i ddnt receive mark sheet for passing in group 1 ( not delivered )

Now I am trying to register for final examination and its asking me for the pe II passing details, and I dnt have roll number for gruup 1 passing detail.

*Field is mandatory ... is there any way i can check my passing detail or atleast get my roll number for that particualr examination held in may 2008.
