Doubt regarding ipcc nov 2014 exams.

Hey. I am an ipcc student and I have a query. I have  registered for both the groups of ipcc, now I want to appear for only group 1 for november 2014 exams, my query is that is it valid to appear for only group 1 after registering for both the groups and whether I can fill the exam form for appearing for only group 1. Please tell me if I can do so or not?
