PREFACE Have you ever been told to do something that you had no idea how to do? If yes, you just managed to fumble your way through it, absolutely clueless of the outcome. This is the predicament that thousands of Secondary School students face today. They have no idea how to study effectively. They re-read textbooks, they refer to their notes time and again and try to memorise as much as they can. The result- they score poorly in their assessments in school and are left clueless as to how to improve. Oswaal Books latest offering- ONE for ALL is going to break down the actual studying strategies for success and empower the students with the 5 E’s of Learning : • Engage : Introduce interesting content enabling better assimilation of concepts • Explore : Provide meaningful insights into various typologies and methodologies for effective exam preparation • Explain : Give better clarification for concepts and theories • Elaborate : Complement studying with ample examples and Oswaal Exam Tools • Evaluate : Conclude with Effective self assessment tools
Oswaal ONE for ALL, as the name suggests is a Complete Toolkit for Excellence. It recognizes the need of students to not only get exam oriented study material for success but also to save time and energy by having all the content in one place, in one book!! As per the Latest National Education Policy 2020, the currently prevalent rigid boundaries of curriculum, pedagogy, and assessment have been moved away from solely rote learning of facts towards more imaginative and flexible curricular structures .Oswaal ONE for ALL is developed keeping this paradigm shift in mind. Revision Notes, Mind Maps, Grammar Charts, Previous Years’ Board Questions, NCERT Questions, NCERT Exemplar Questions (in Maths & Science), Questions from Deeksha & NTSE preparation, all put together make Oswaal ONE for ALL a Trusted Examination Companion for every student. 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 help us in continuous improvement! We, at Oswaal Books, wish you all Happy Learning and a Successful 2020-21!

CENTRAL BOARD OF SECONDARY EDUCATION CBSE-Acad/Circular/2020 All Heads of Institutions affiliated to CBSE
Date: 07 July, 2020 Circular No: Acad 47/2020
Subject: Revised Academic Curriculum for the session 2020-21 The prevailing health emergency in the country and at different parts of the world as well as the efforts to contain the spread of Covid-19 pandemic has resulted in loss of class room teaching due to closure of schools. Therefore the Board has decided to revise the syllabi for classes IX-XII for the academic session 2020-21. The changes made in the syllabi have been finalised by the respective Course Committees with the approval of the Curriculum Committee and Governing Body of the Board. The revision of syllabi is a measure taken due to the extraordinary situation prevailing in the country and at different parts of the world. Considering the importance of achieving the level of learning, the syllabus has been rationalised to the extent possible by retaining the core concepts. The Heads of Schools and Teachers may ensure that the topics that have been reduced are also explained to the students to the extent required to connect different topics. However the reduced syllabus will not be part of the topics for Internal Assessment and year-end Board Examination. Alternative Academic Calendar and inputs from the NCERT on transacting the curriculum using different strategies may also be part of the teaching pedagogy. For Elementary Classes (I-VIII) schools may follow the Alternative Academic Calendar and Learning Outcomes specified by NCERT. The revised syllabi are available at the link: http://cbseacademic.nic.in/Revisedcurriculum_2021.html

F.No.CBSE/DIR(ACAD.)/2020
Circular No. Acad-18/2020 All Heads CBSE affiliated schools 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-X (2020-21) year-end/Board Examination are as under:
Classes IX-X Year-end Examination /Board Examination (Theory) Composition
(2019-20)
(2020-21)
Existing
Modified
Objective type Question including Multiple Choice Questions
Case-based/ Source-based Integrated Questions (introduced through SQP 2019-20) Short Answer type/Long Answer type Questions.
Objective type Questions including Multiple Choice Questions- 20%
Case-based/ Source-based Integrated Questions- 20%
Short Answer/Long Answer Questions - Remaining
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.
