Preface, Our education system effectively provides an introduction to the concepts of, Math and Science and helps us understand the underlying concepts. But in, its overly generalized approach, which aims to enlighten and test all students, of varying caliber and interests, it leaves the exploration of application of all, these concepts completely on the students., This workbook is designed to enable students to explore Maths effectively., Designed in accordance with the requirements of the Maths Olympiads,, the workbook is an efficient tool to achieve comprehensive success at the, ISFO – Maths Olympiad., The main aim of this workbook is to assist students in developing and, improving their ability to solve problems., Each chapter of the book consists of 3 sets of questions., • Section A (Mathematical Reasoning) : This section is created to test, the knowledge of mathematical concepts and topic pertaining to the, respective grades., • Section B (Everyday Maths) : This section deals with the application., • Section C (BrainBox) : Questions to prepare students with HOTS (Higher, Order Thinking Skills) based on the syllabus provided., Logical Reasoning section is provided to equip students with verbal and, non-verbal analysis and reasoning skills., Sample Test Papers and Answer keys have been provided to accelerate the, learning process., , 3
