Provisional admission to ca final exams may 2014.

I have received a letter dated 9/4/14 stating that I have been PROVISIONALLY admitted to CA Final May 2014 Exam. Also it asks to revalidate my registration if required and to confirm that I will be serving my last 6 months of articleship as on 1.5.2014. So what do I have to do now? P.S. This is my first attempt and I have regd. for CA Final since 20.10.2013. Please help.
