Mohd. Rafi's book is also very good. I have Campared Bangar and Rafi in the bookstore, and concluded that Rafi is better book considering the presentation and explanations keeping in mind the student point of view.
BANGAR'S TEXT IS THE BEST. IT COVERS ENTIRE EXAM REQUIREMENTS. 100% QUESTIONS WILL BE FROM BANGAR ONLY.YOU NEED STUDY ONLY THIS TEXT AND RECENT CASE LAW BUK PUBLISHED BY ICAI. 80% + ASSURED
