Applicabilty depends upon the FY relating to the assessment year your are writting the exam.
Lets say, for Nov'2010, exam paper question will be framed for FY 2009-2010, so applicable Assessment year is 2010-11.
You have to see the point of time you are writting the exam.
Where as for indirect taxes, the applicabilty is based on the date of notification, generally it wil have immediate effect.
