PREFACE
India is one of the youngest economies in the world today. Hence, it becomes imperative for our education system to churn out more of learners than ever before. It is the learners’ mindset which will set us apart from the rest of the world. Hence, by the way of Education, we must sow the right seeds today to reap the benefits in the years to come. It is very rightly said that if we teach today as we taught yesterday, then we rob our children of tomorrow. With this vision, CBSE, the national level board of education in India for public and private schools, has yet again updated and released its curriculum for the upcoming Academic Year. With all the refreshing changes and updates, the way ahead looks exciting for students and teachers alike! We at Oswaal Books, are also extremely upbeat about the recent changes. We have made every possible effort to incorporate all these changes in our books for the coming Academic Year. Latest Typologies of Questions like Multiple Choice Questions, Fill in the Blanks, Match the Following, etc. have been exclusively developed by the Oswaal Editorial Board and included in our Question Banks. All chapters in Oswaal Question Banks are arranged 'TOPICWISE' where each topic is explained in detail and covers all typologies of Questions specified by CBSE along with well-labelled and high-quality figures/ diagrams for faster learning. All the Questions from Latest edition of NCERT Textbooks, fully solved are included in our books. Along with this Previous Years ‘Questions from Kendriya Vidhyalaya Sangathan & DDE are also included. We at Oswaal Books never try to teach our readers. We on the other hand, provide them the conditions in which they can learn and train their mind to think! After all Education is what remains after one has forgotten what one learned in school. Some of the key benefits of studying from Oswaal Question Banks are : 1. Chapter-wise/ Topic-wise presentation for systematic and methodical study st 2. Strictly based on the latest CBSE Curriculum released on 1 April 2020 and NCERT Textbooks 3. Previous Years' Question Papers from Kendriya Vidhyalaya Sangathan & DDE are included 4. Questions from various competencies including-conceptual understanding, creative expression, reasoning, justifying and applying literary conventions. 5. Latest Typologies of Questions developed by Oswaal Editorial Board included. 6. Mind Maps in each chapter for making learning simple. 7. 'Most likely Questions' generated by Oswaal Editorial Board with 100+ years of teaching experience. 8. Suggested videos at the end of each chapter for a Hybrid Learning Experience. We have taken due care in developing this book. There have been a lot of people who have helped us in our journey. We would like to offer heartfelt gratitude to all of them- our authors, editors, reviewers and specially students who regularly send us suggestions which helps in continuous improvement of this book We, at Oswaal Books, wish you all Happy Learning and a successful 2020-21 !!

I am a big fan of Oswaal Books. These series of books have been a life saver for me, especially for last minute revision. I would like to thank-you for the amazing segregation of board questions for our revision.

Subject : Strengthening Assessment and Evaluation Practices of the Board
Competency Based Education (CBE) is an outcome based approach to schooling, where attainment of goals takes priority. Learning Outcomes (LOs) are defined in terms of competencies and capacities, which students acquire and demonstrate at the end of instructional programme. In CBE, explicitly defined learning outcomes guide instruction; instruction is more flexible, learner centric, learner-led and provides multiple opportunities for learning; and assessment is authentic and examines if the students are able to apply required concepts in real life situations.
The Board vide Circular No. Acad-05/2019 dated 18.01.2019 has adopted Learning Outcomes developed by NCERT and the theme of the Capacity Building Programmes for the year 2020 is Competency Based Education. Augmenting the thrust towards CBE, the Board is initiating corresponding changes in the Examination and Assessment practices for the year 2020-21 onwards.
While the overall marks and duration of examination shall remain same, change in the composition of assessment tasks would help us achieve the desired ends.
The changes for classes IX-XII (2020-21) year-end/Board Examination are as under :
Classes IX-X Year-end Examination /Board Examination (Theory) Composition
(2019-20) Existing
(2020-21) Modified

Curriculum document for the Academic Session 2020-21 to be released in March, 2020 will reflect the respective changes for the individual subjects.

March 31, 2020 Cir No Acad-21/2020
All Heads of Institutions affiliated to CBSE Subject : CBSE - Secondary and Senior School Curriculum 2020-21 1. The curriculum refers to the lessons and academic content to be taught to a learner in the school. It encompasses general objectives of learning, courses of study, subject- wise instructional objectives and content, pedagogical practices and assessment guidelines. 2. The curriculum provided by CBSE seeks to provide opportunities for students to achieve excellence in learning based on the National Curriculum Framework-2005 and are adopted/ adapted from the NCERT Curriculum. 3. It is important that schools ensure curriculum transaction as per directions given in the Curriculum document. The subjects to be taught must be as per syllabi given. Before going through the syllabus, the teachers must be well-versed with the strategies given in the initial pages of the curriculum. Therefore, it is desired that the head of the school may circulate the initial pages of the curriculum and the syllabi to all the teachers and ensure that curriculum is transacted as per the directions given therewith for optimal learning and specifically to avoid difficulties for students at the time of the examinations. 4. It is reiterated that any deviation in transaction of the curriculum may seriously affect assessment of the student’s learning level and the preparation for the Board examinations. Please note that the Evaluation will be carried out exactly according to the syllabi given for the current academic year. Sample Question Papers with detailed design of the Question Paper will be made available on CBSE website during the progress of the academic session for reference. 5. Please refer to Circular No.Acad /18 dated March 16, 2020 on strengthening the Assessment and Evaluation Practices of the Board to know about the proposed changes. Hence, all the teachers and students are cognizant of the Curriculum Document (Initial Pages and Syllabus) in totality, which is available on www.cbseacademic.nic.in. 6. The Board will consider possible loss of instructional time in the academic session 2020-21 due to the closure of schools to prevent spread of COVID-19 as per directions from the Central Government and various State/UT Governments. Revision if any required in the syllabi and course and the pattern of Examination of various subjects on account of the above will be chalked out in consultation with the Course Committees of each subject as well as with the Examination Committee of the Board and notified in due course of time.
