Malcolm Forbes said “Education's purpose is to replace an empty mind with an

open one” and this is something which is always followed by Tamil Nadu Board in their

Samacheer Kalvi system of education. The aim of Samacheer Kalvi Curriculum is not just

to let learners obtain basic knowledge but to make them life-long learners.

The purpose of this book is 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. This book is designed in such a way

that students can set their own goals and can improve their problem solving and thinking

skills.

This book is strictly as per the latest Samacheer Kalvi Blueprint & Design for SSLC

Exams. It contains variety of questions from latest textbooks. It contains all types of

questions like VSA Questions (Very Short Answer), SA Questions (Short Answer), MCQs

(Multiple Choice Questions) and LA Questions (Long Answer). A synopsis is given for

every chapter which contains important points from that chapter. Each chapter has high

quality figures wherever required for better, fast and clear understanding.

OSWAAL SSLC Question Bank is different and better in terms of High Quality

Questions which are developed by 'OSWAAL Expert Panel'. The Question Bank is

arranged ‘TOPIC-WISE’ where each Topic from every Chapter is explained in detail.

‘KEYWORDS’ are highlighted to develop student understanding of marking scheme.

Through OSWAAL Books students are taught how to think, not what to think. We

at OSWAAL Books try to use quality content, standard language, creativity and high

quality figures, which makes readers to enjoy it because we believe if our readers don't

enjoy reading our book then there is no use in reading it at all. This is one of the reasons that

the scope of this book extends from students to teachers. Teachers can use this book as a

perfect teaching guide and students can use this book for good learning and

practice.

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

students whom we request to send suggestions regularly which will help in continuous

improvement of this book and will make this book “One of the Best”. Wish you all Happy

Learning.
