law , costing , SFM , financial reporting , isca dont change frequently .
in auditing only SA changes & i am sure there will not be further new amendments because already there were many amendments till april 2010.
as far as law is concerned , few amendments will surely come , but thats not a big deal you can continue your studies in law , the amentdments in law are not frequent & they are not too big .
now it comes to DT & IDT , these two subjects are very dynamic therefore study them in last year .
above said things are my personal opinion .
all the best
