The bulk of this question bank comprises Explanations. Some questions which very clearly demand the knowledge of FACTS have been given needless explanations which only adds to the bulk of the book without any corresponding improvement in the overall quality. Certainly not a MUST-Have in your UPSC arsenal.
Please check all pages because pages are missing. In my book pg 151-182 are missing which contains 92 questions. This is publisher's mistake. So don't get cheated. Check your book thoroughly after purchasing. However content wise book is excellent.
Its not necessary to order this book and also the art and culture book of Vinay sir. Manageable without ordering as well. The polity question bank is good though. Helpful in quick revision of important chapters.
