CA final - Old Syllabus Nov 2020 exam

I applied for Group 1 for May 2020 CA Final - Old syllabus attempt. Now as May 2020 attempt is merged with Nov 2020 attempt, now i want to apply for both Groups,

so just a question, while filling application form for Nov 2020, I just have to apply afresh form indicating BOTH Groups applied for and pay the differential fees. Anything else would be needed or what?

Also, only Self attested Article completion Certification is sufficient ? as it is not mentioned on Certificate format to get it attested through Principal or Member of the institute.

I will appreciate your reply.

Thanks,
