Important clarification about applicability CARO to May 15 Exams.
 
CARO 2003 was practically applicable upto FY 13-14, so it was applicable upto Mar 14, but ICAI explicitly included it with start mark in Nov 14 exams,  When May 15 course was announced it was not having separate inclusion about CARO 2003, further it is removed from new practice manuals.
 
So officially it is not applicable. CARO 2015 came on 11th April, so it won’t be applicable for May Exams.
 
Final Conclusion CARO 2003 / 2015 not applicable for May 15, 90% chances it won’t be asked 10% chance ICAI can go for foul play.
 
still if they ask it, answer it as per old CARO 2003
