Confused

I gave my ipcc group 1 in may 14 attempt and currently taking group 2 coachings for nov 14.. The problem is that my result will come in mid august and if the result is negative then it would be very difficult for me to give both groups in nov14 because only 2 months.. After my exams of group 1 i have not studied group1 subject but i am regular with my group 2 subjects ie doing homework etc.. If i fail in group 1 then should i give both groups or only 2nd one... Though the message is long but please reply
