CA Final Audit book by Pankaj Garg for OLD Syllabus

Students preparing for the CA Final old syllabus exams in November 2020 are facing a dilemma regarding Pankaj Garg's latest Audit book. The book explicitly states it's for the new syllabus only, unlike other authors' materials which are often adaptable. This leaves old syllabus students without a clear textbook option. The discussion seeks advice on whether the new syllabus edition can be used by old syllabus students.
