November Exam & Revalidation of CA Final registration.

Aum Maheta (none yet) (216 Points)

25 May 2017  
My CA Final initial registration is expiring on 22/8/17. My 1st group is pending. In the mean time (i.e: before 22/8/2017) if new course of CA Final is announced and I make Revalidation application for registration after 22/8/17, which course ( new course or current course of final) will be applicable to me in November, 2017 exams and onwards?
 
For the benefit of students registered in current course certain No. of attempts will be decided & announced by Institue along with announcing new course.
 
When should I make an application so that I can get benefit of appearing in current course for certain attempts?
 
Please Help.
