Everchanging law vis-a-vis syllabus.

if you mean Ind-AS is what you read some months ago, it may not be required for your exams, as they are not yet applicale; in any case, for May 2012 exams better read the current AS which are in force now; ICAI will notify in the CA students journal, about the applicability if ASs for MAy 2012 exams. only when ICAI notifies that Ind-AS or the "draft converged accounting standards" whatever you read is applicable for May 2012 exams, you may focus on them.

All the Best for your exams
