Group 1 or group 2???

Hello freinds,,, I want a suggestion from you all.... I am currently doing industrial training in gurgaon and the company will give me only two month preparation leave for my ca final exam which is due in May 2014. I want to give only one group as I ll not able to prepare for both the groups.I am not taking any coaching also. I want to ask you all that which group should I attempt in May 2014?? (Pls comment considering syllabus changes in few subjects after may 2014) Thanks in advance...!!!
