Hi Saurabh,
I had gone through some sample topics and compared the same with ICAI material/Padhuka and V K Agarwal. For Perr Review topic, ICAI gives two definitions (one general and other as per statement), whereas it provides onl;y one.Again objectives are not as per ICAI study material. As we all know, in most of the subjects, ICAI prefers language in its material.
Otherwise concepts in book are good. It contains question bank and revision points with audit standards in a sigle book, unlike other books. But not satisfied about the content.
I agree with PSPSPS and would like to suggest a step ahead. If you have time you can go for ICAI material. It looks bulky as page margins are more, paper size is small and not very loving font used. If you see V K Agarwal earlier editions, it was nothing but copy of ICAI material with small font size and big paper/book size. I m personally not comfortable with "tabular" books like current agarwal edition or Surabhi madam.
You must have obeserved that this being a core subject CA profession, even rakers struggle to get 60-65 marks (who score 80-85 marks in vast subject like DT and around 90 in subjetcs like costing). This is just because books in the market do not cover everything in ICAI material and in the same language of ICAI (earlier editions of VK were covering most of the things but now they copied surabhi bansal style of tabular book and reduced a lot of content and case laws). In some books contents are not complete and in some others strandards are given in separate book (say Padhuka is good and comprehensive but standards book is different).
So if possible stick to ICAI material. In PE II I could score 68 marks in audit without any classes just by studying module.
From my experience, I still believe in ICAI material. And this is must for at least Audit and ISCA.
