Regarding Applicability of AS 30, 31, 32

I am a Final(New cousre) student with an attempt in the coming May.
This is in context of AS 30, 31, 32 being made compulsorily applicable from 1st April, 2011.
As a result of this applicability, various Accountind standards(AS 2, 21, 23, 26, 27) have been subjected to limited revision.

My query is straight. Do these New standards 30, 31, 32 apply for the examination to be held in May 2011. Because otherwise, the limited revisions of AS's mentioned above would not be applicable any ways.

Btw, it's not easy to understand the practical impact of AS 30 on financials(books on AS's have little problems on these standards). Please suggest any source from where I can get a full package of conceptual practical problems in relation to the standard.

Also regarding IFRS, to what level are we supposed to be thorough with them?

Awaiting objective answers.

Thanks :)
