Ca final registration

I have to appear for ca final group II exams on May 2016. My final registration date is on 8/3/11. we have to re-register if the registration is more than 5 years old. In my case the reg. date won't be more than 5 years if exam forms come out in february, but if i consider the exam dates of may 2016 then it will be more than 5 years. do i need to re-register? do reply. urgent.
