First check whether there are any changes from the syllabbus which applied for May 2011 CA Final exams.
For May 2011 in IDT , service tax changed, in ISCA - 4th and 8th chnaged, In fm, students were expected to do practice manual and for DT, supplementary for Direct Tax for May 2011 was issued and Select Cases applicable was uploaded in ICAI Site.
So whatever was applicable in May 2011, from that is there any big difference in Nov 2011. Only FOR IDT , FOR NOV 2011, SOME CHANGES HAVE BEEN MADE IN COMPARISON TO MAY 2011---WHICH CAN BE SEEN IN RTP ISSUED FOR NOV 2011.
If its same as what was applicable for May 2011, then no need to worry as only practice manual for all subjects done, it would be sufficient.
Do correct me if Iam wrong in above conclusions
