Am really sorry..Yeah u are right..AS 30-32 are yet to be made mandatory. Thanks for the correction.
Of course ICAI has to give students enough time. But in case IND AS are finalised and made applicable on a voluntary basis from 2015-16, ICAI can(if it wants to) issue a notification in 2015 itself regarding the applicability of IND AS for May 2016 exams and issue new study modules incorporating IND AS one year in advance.. And I amnt saying that complex topics like amalgamation,consolidation,etc. will be as per IND AS. These topics can be dealt with in accordance with the existing standards, since IND AS are going to be implemented only in a phased manner and the current accounting standards continue until IND AS are fully implemented. But ICAI may introduce IND AS as a part of its syllabus which u will have to study alongwith all the existing AS(may be the coverage shallnt be in-depth as in the case of existing standards). I dont think we can say with 100% certainty that IAS willnt be applicable at all for May 2016.
