Please help me

I have given ipcc group-1 attempt in nov 2012 and i have not cleared it but i have got an exemption in accounts with 64 marks......now i am confused whether to attempt both groups or only group-1 in may 2013...as i have not started preparations of group-2 yet....now as the time left is less than 3 months i am confused whether studying for 6 subjects is possible....should i go for group-1 alone or both..... Please help!!
