Is baar Oswaal ne kamal kar diya. The updated 2026 edition has even more practice questions and the solutions are more detailed than ever. My child's teacher also praised the quality of this book. Already planning to buy more titles from this series.

We purchased this for our child and it has been very effective. The solved examples are clear and the practice questions are well-graded from easy to difficult. My child now looks forward to studying every day. Great product from Oswaal!

Bahut pyaar se banai hui book hai. You can see the care put into every chapter and every question. My daughter started preparing with this book just six weeks ago and her logical reasoning skills have improved dramatically. Excellent work by Oswaal team.

Very satisfied with this purchase. The book is well-printed with clear diagrams and examples. The previous year papers section is especially useful for understanding real exam standards. My son's preparation has gone to the next level with this guide.

This Oswaal book is a complete package for Olympiad preparation. It has concept notes, solved examples, practice questions, previous year papers and sample papers all in one place. My child does not need any other book. Outstanding quality.
