CBSE always believes in Global Trends of Educational Transformation. The CBSE

curriculum gets its lead from National Curriculum Framework – 2005 and Right to Free and

Compulsory Education Act – 2009. The aim of CBSE Curriculum is not just to let learners

obtain basic knowledge but to make them life-long learners. CBSE always updates and

reviews the syllabus to make it more relevant with educational transformation and in last

few years the chapters and topics which CBSE has added are very interesting and increase

practical knowledge.

Oswaal Question banks are designed to nurture individuality and thus enhance

one's innate potentials which help in increasing the self-study mode for students. This book

strengthens knowledge and attitude related to subject. It is designed in such a way that

students can set their own goals and can improve their problem solving and thinking skills.

The journey of this book is never ending as this book is reviewed every year and

new questions, previous year's examination questions, new HOTS or any change in

syllabus is updated time to time. Also regular review and reader's feedback increases the

efficiency of this book gradually.

Moreover, every Question Bank strictly follows the latest syllabus and pattern, and

contains more than sufficient questions and brief description of chapters, which help

students in practicing and completing the syllabus. Higher Order Thinking Skills (HOTS)

questions, solutions to important NCERT questions and questions from Kendriya

Vidyalaya Sangathan (KVS) makes this book complete and very efficient. Solutions are

always checked twice and tried to make precise as per marking scheme. Practically, this

book provides students everything they need to learn.

At last we would like to thank our authors, editors, reviewers and specially students

who regularly send us suggestions which helps in continuous improvement of this book

and makes this book stand in the category of “One of the Best”. Wish you all Happy

Learning.
