Ca registration query

I would like to clear my doubt regarding delay in registration for final exam. I have passed my Group 2 of IPCC in May 2019 and my articleship got over in in Feb 2019.

I wasn't able to register myself for the final course after clearing Group 2 of IPCC due to some personal problems
I was registered under old course scheme and now my SSP shows ipcc course has lapsed even after qualifying both the groups.

So I wanted to enquire the procedure I need to follow for appearing in the final exam for the month of Nov 2021.

Kindly assist me in this regard as soon as possible.
