hey Shobit A.Y. 2011-12 is applicable for NOV 2011 but as said earlier there are many changes applicable to you hence get updated by buying a amendment book from the institue to be sure
the book is right but be updated with the amemdments in finance act 2011, notifications, c-rculars which is retrospectively applicable from AY 2011-12 and is issued 6 months before the exam. check ICAI website for this....or find RTP for your attempt on CA website.
