Need your response for this query

Guyz.. I had filled up the form for both groups for the may 2011 final attempt.. but as I was not prepared for the 1st group... I decided I will not appear for Grp 1... though I had enquired with my friends about this.. but still need to confirm.. will there be any problems for my group 2 result if I have not appeared for grp 1... pls confirm.. 

Thank You
