My question is about the old course and new course of CA Final. I have already completed all my tuitions of first group from old course and appeared for this exam now, that is in May 2018. And it doesnt look like that I'm going to clear it. I was gonna start my tuitions for group 2 now. So my question is that can i opt for group 2 in new course? Having not cleared group 1 yet?
Or will i have to convert both the groups into new course? If yes then how much difference is there between old course group 1 and new course group 1.
