Ca final elective exam time 4 hours instead of 3 hours?

Hello Friends

I was going through the May 2018 question papers of various Elective courses on ICAI's website and saw that on the first page of every question paper, top left hand side 4 Hours was written instead of the usual 3 hours. For all other subjects the question papers had 3 hours written. Does that mean we will get 1 extra hour for Paper 6 elective and the timings will be 2 to 6 p.m. instead of 2 to 5 p.m.?

Thankyou

Regards
