Your 1st attempt will be due in Nov, 2010 i.e. after completion of 2 and 1/2 years of Articleship. As the last attempt for CA. Final under the old scheme is in Nov, 2009 for which eligibility is completion of 2 years of articleship, but as you have to shift in the new scheme under which eligibility is completion of 2 and 1/2 years of articleship, so in your case it will be Nov, 2010. If any subsequent happening has taken place under which eligibility has been reduced to 2 years under the new scheme please let me know about that.
