Yes, 4 months r enough.., even if u starting every subject for first time... For AUDIT, IT-SM will tak total 17 days, LAW will take 13 days... So in a month, u can finish all the theory subjects to clear atleast.... Moreover, a.c take 25 days, tax take 20 and cost-fm should take max. 15 days.... So from 4 months, i.e 120 days, u finished off ur stdies in just 90 days..., that means u still have 30 days revision., 5 days revision for each subject.., and that is JUST MORE THAN ENOUGH....
I agree with dheeraj sir....
4 months are more than enough 4 pcc and ipcc....
In my case also i have prepared everything in 2 months and still manage to clear both the grps in a single attempt but i was a student of ipcc.....
