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. Simply outstanding quality.

Excellent resource for Olympiad exam preparation. The previous year solved papers are very authentic and help children understand what to expect in actual exams. My son's performance has improved considerably after practicing from this book daily.

Purchased this book set for my daughter who is appearing in SOF exams this year. The content quality is exceptional and the solved answers are very detailed. She has already completed two chapters and loves the format. Worth every paisa spent.

This is the best investment I made for my child's Olympiad preparation. The book covers everything from basic concepts to advanced problems. My daughter improved her rank from 500 to top 50 in the school. Cannot recommend this enough to fellow parents.

We purchased this for our Class 1 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!
