Agreed with Virag, You have to register on or before 5th Dec'11, to appear for exam in june'12,
1. once you registered, you have to send answered testpapers, before 10th of Feb'12, If you passed in them, you will get coaching completion certificate by March,
2. ICWA will be conducting seminar, group discussions, probably in the month of April, you have to attend atleast one to write Inter-one group exams, and attend two seminars to write two groups at a time.,
After registering you will have abt 7 years to finish the course,
Once you get coaching completion certificate, you will 5 attempts to finish the group..
All the best
