PREFACE
Who is this book for?
We are delighted to present the updated edition of the CBSE Questions Banks for the 2022-23 academic
session for Class 10. This edition is based on the latest CBSE Syllabus and Scheme of Assessment and
Evaluation Practices of the Board for the Session 2022-23. National Education Policy 2020 has affirmed
the need to move from rote to competency based learning. The Board has taken multiple steps towards
the implementation of Competency Based Education (CBE) to equip the learning to meet 21st Century
challanges proactively.
Why is this book different?
The structural changes in Education that are being brought in by
the latest Syllabus and the new National Educational Policy (NEP)
resonate with our approach of focusing on deeper understanding The new way of learning;
instead of rote learning. Available for all subjects, these books Blended Learning
have been designed to help students achieve high scores in their
Board Examinations. Prepared by the Editorial Board of Oswaal The pandemic introduced us

All Heads of schools affiliated to CBSE
Subject : Assessment and Evaluation Practices of the Board for the Session 2022-23
National Education Policy 2020 has affirmed the need to move from rote to competency-based learning. This will
equip the learners with key competencies to meet the challenges of the 21st century proactively. Accordingly, the
Board has taken multiple steps towards the implementation of Competency Based Education (CBE) in schools.
These range from aligning assessment to CBE, development of exemplar resources for teachers and students on
CBE pedagogy and assessment and continued teacher capacity building.
In this context the Board has released Circular No. Acad-05/2019 dated 18.01.2019; Circular No. Acad-11/2019 dated
06.03.2019; Circular No. Acad-18/2020 dated 16.03.2020; Circular No. Acad-32/2020 dated 14.05.2020 and Circular
No. Acad-31/2020 dated 22.04.2021. In continuation to these circulars, the Board is initiating further corresponding
changes in the Examination and Assessment practices for the year 2022-23 to align assessment to Competency
Based Education. Therefore, in the forthcoming sessions a greater number of Competency Based Questions or
questions that assess application of concepts in real-life/ unfamiliar situations will be part of the question paper.
The changes for classes IX-XII (2022-23) internal year-end/Board Examination are as detailed:
