rumour to say June will be the next attempt
and regarding revised modules
they are updated to be more student friendly as krishna said so
and as per the director board of studies it will always be applicable for nest upcoming exams as the syllabus is same but content is widened a bit
in isca there were a lot of new small topics were inserted in July 2010
still it was applicable for next examsi.e nov 2010
and around 25 mraks direct questions were from it
ICAI did not mention or announce any such changes in the website
it was due to many people ( including me ) who have talked to and mailed and thry e sahayata pointed this figure out to ICAI
and then they just announced that ok it will be applicable
as per Kapoor sir " the changing of icai's book is and ongoing process and we need not again and again declare that this or that publication has been amended and are applicable for exams
for the convenience of students we have already host the updated books on website, so it is always beneficial to read from those updated content for the exams "
For may 11 the updated books have not still been hosted on website
so keep a watch on it !!
good luck
