Oswaal books are always reliable and this one is no exception. The 2026 exam edition has updated content and more practice questions than previous editions. My daughter found it very helpful for her Science Olympiad preparation. Highly recommended.

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!

Yeh book lene ke baad mera beta roz khud padhai karta hai. The colorful layout and clear fonts make reading enjoyable for children. Previous year papers are a great addition. Delivery was fast and book quality is top notch. Highly satisfied!

Bahut comprehensive book hai. The coverage of all subtopics within each chapter is thorough. My child's teacher was impressed to see such a well-structured study guide. The reasoning questions especially are very thought-provoking. Highly recommended.

Very well organized study material. Each chapter starts with concept clarity and then moves to practice questions. The achievers section questions are quite challenging which prepares students for the toughest part of the exam. Full marks for this book!
