I'm gonna write my IPCC exam on November 2017,so I'm confused which books to refer for Paper 2. Law Ethics n Communications, as some of my frnds suggested to refer Munish Bhandari's book n few others suggested to refer Institute's Study material and practice manual and finally few friends suggested to refer Coaching class material (I'm currently studying in JK SHAH)
So can anyone answer my question.. Thx in advance
