CA final ... Group1

FR ICAI
SFM ICAI PM, vinod Kumar agarwal or mayank kothari
Audit pankaj garg, aarthi lahothi
CE law ICAI SM +Questions from pankaj garg

For FR-
refer 1st SM of ICAI syllabus then after go for practice book of Praveen Sharma sir and also do practice of MTPs ,RTPs and PY Questions.
(that would be more enough to get good marks in 1st attempt)

For Law paper -
SM of ICAI is best, RTPs, MTPs and make your own notes that will help a lot and also solve different case studies that is available on ICAI BoS Portal.

For SFM-
SM of ICAI and for practice you can go for old PM if have much time to prepare.
RTPs and MTPs is must for any subject.
(honestly speaking you don't need any reference book for this subject seriously.. it's enough to clear this paper)

and last but not the least, for Auditing paper -

Pankaj sir book is enough for practice to get good questions from exam point of view and explained in a better manner.

(I think this will going to help you much better)
