I liked the product because it seems to cover all of the topics I think are needed to comprehensively study Economics for UPSC Pre. Haven't yet moved on far along in my Mains Prep to have any judgement. The book could have had better paper quality, but that's trivial in this case, since the content is good. The writing style could be better, and the book is a bit difficult to understand for a first time reader like me, but I am relatively happy with it.
MCQs and Q&As are given at the end of the book, along with that year's Economic Survey summary and Budget Discussion.
