CA Final After 5 years - Suggestions Pls

I am planning to write my CA Final Exams almost after 5 years in May 2020. My last attempt was in 2014. Im seeking help from members of this group in the following aspects: 1) which group is better to attempt. I am a working professional so i dont have the time to attempt 2 groups at the same time. 2) Is it advisable to convert to new syllabus? 3) I see that AS is part of syllabus in FR for old syllabus. So if i attempt 1st group in old syllabus then i should be spending time on learning AS which i think may not be useful considering the existense of Ind AS. So what do you suggest. Kindly provide me your valuable inputs 🙇
