Need genuine suggestion!

First of all, i am happy because i have cleared first group of CA Final in May 2014, result of which were announced on 8th Aug 2014 :)

I was waiting for the result, was not sure whether will clear the same or not, because of which i didnt studied a single page of second group and worked hard in articleship.

Coming to the conclusion, only 83 days are left for the first exam to begin, i.e Advanced Management Accounting on 15th Nov 2014,

would i be able to study all 4 subjects of group 2 from level zero in the above mentioned period?

Or should i go only for exemption in 2 subjects? (DT & IDT or Costing & DT or Costing & IDT).

Waiting for a genuine advice :)

Thanks in advance!
