I just saw the mock paper issued by the institute. If you go thru it carefully, u find that there are both internal and external choices in the question paper. BUT, choice has been removed in Costing alone.. When the ICAI comes out with such mock paper 20 days before the exam, I am pretty sure that this will the pattern for the November 2009 examinations. Maybe the change in the costing ques paper pattern is the ONLY change in the pattern. I request ppl with knowledge/experience on such matters to come forward and give their opinion.
