Hey Tausif
I hope your doin your IPCC
Costing FM
Even though this is a problem paper theory has vast relevance here...it comes for nearly 40 marks which decides ur fate for the exam..cos in its prob aspects the ques can be of any type..u cant be sure about that part..so the best way to deal this paper is be very good in theory and score the max of that 40 marks and ur sure to pass...For costing main theory lessons are the first few..till that OH chapter...but mind you it can come from other chapters as well...i mean short ques..so don do selective study friend...And about FM its not as vast as costing..so study that fully...the financial instruments also very imp(no ques was askd from it for nov 09 thou)..
Accounts
Here i don think u ll have to study the theory part very much as like other prob subjects...Some chapters have theory related to company law..study that well...Study all AS very well...its damn imp..u can get both prob and theory ques from it..and for IPCC its weightage was a lot in nov 09 exams..
TAX
About income tax study recent amendments well..then in this paper u need to know the thoery aspects well like dates and amounts if u have to do the probs..so U have to learn the theory part well and good...
For IPCC again there is service tax and VAT for 50 marks which is very easy to learn...learn the 5 services u gotto learn and the definitions in it very well...its always bttr to follow the institute materials for that because all other books may be PCC IPCC combined and may not have full aspects of serv tax and VAT..its very easy to finish when compared to the vast income tax..so study that well and its easy to score there
