friends its true there are few changes but not that much that u need to buy the new study material , and even its true that all the matters in study material are not coverd in pracital manual but if u buy the new study material there are lots of confusing for example chapter 22 of sox had been change to chapter 3 , if u get new one u find that there are some chapters are missing but actually its not the case , so plz dnt go got the new study material just take out the copy of isca chapter 4 and 8 , new accounting standards and new applicable standard of audits
but if u look at practical manual they are quite good , few compare it with comilpers but in compilers the notes for each chapter revision is not attach and many new questions are not there ,infact to get the study material u cover 90% of contains of all the subject and also the way how the eaminer wants answer from you , also it provide a easy refrence and quick revision
go for the change material and download it and but new practiacal manual its the bottom line for all ca final students for may 2011
