I have started my articleship in 1st November 2007. After 3 1/2 years it ends on 30th April 2011. But there was a mistake in calculation during my registration and it was printed in my identity card as 31st may 2011. Whether I can attend my CA Final exams in May 2011? What is the procedure to correct the same?
