CBSE 10th Topics Removed for 2020-21: The Central Board of Secondary recently released the revised syllabus for all subjects of class 10. Board has deleted some portion of the syllabus for the ease of students who will be taking their CBSE Board Exam next year. Due to COVID-19, almost the first four months of this session have already passed in passive learning through self-study, online assignments, or online classes. So, to compensate for the loss of this study period and taking care of the learning outcomes so that the core concepts can be retained for students, CBSE announced a major syllabus reduction for the academic year 2020-21.
