Which book is worth buying for Final Audit?

i am studying with CA pankaj garg sir's book. it is good

If you can not cover the Whole syllabus now by Pankaj Garg Sir's books then You should at least buy his Scannar. its Very good provided you already read whole audit syllabus

if you are appearing for ca final may 2019 exams then as per my opinion you should go for Surbhi Bansal Maam book. As it covers chapters for both old and new syllabus. apart from this another outstanding feature of this book is that each chapter is followed by MCQ . even each SA is followed by MCQ. this book should be supplemented with PM and Study material. ICAI study material contents are must . atleast read one time and then read from this book.

thank you and congratulations

Agree @ Pankaj Garg sir book is best for Audit
