Hi Preeti!
I have recently cleared my Final C.A. Exam in Nov'05 and according to me, We professionals have to pay a lot of concentration in our Exam preparation and if the preparation is good, you will automatically get confidence which will enable you to clear easily.
According to me, We have to refer every subject atleast for three times before exam and continuously make a revision to get a good confidence. Now, as you have 2 months time, You should try to see that you may allot not more than 40 days for learning process and in the remaining 20 days, you have just to revise it.
Accordingly as per your capacity, allot time from today itself but remember :-
(1) Every subject should be done properly and not with half hearted by skipping.
(2) Keep concentration first in any one group and do all the subjects of it.
(3) Not to do study say 2 subjects in one group and say 2 subjects in another group.
So, in nutshell, first try to keep concentration in a single group and revise it thoroughly so that you make 100% confident to pass in it. PAY MORE TIME IN REVISION AFTER LEARNING.
WISH U ALL THE BEST!!!
