ICAI's IPCC module of Auditing and assurance says about SA 200 and SA 200A something different. It shows date of effect in 1 April 1985. Book from Surbhi Bansal, is much different on this matter. There is nothing like 200A and plus SA 200 is also different and date of effect is 1 april 2010. What should i study? Plus, how should i study SAs as exam point of view? Thanks
(Module is of 2011 and Bansal's book is in 8th Edition,)
