The National Council of Educational Research and Training (NCERT) has removed a chapter on the periodic table from Class 10 CBSE science textbooks as part of the council’s “rationalisation” exercise. However, the Class 11 chapter on the topic remains part of the syllabus. “NCERT drops full chapters of Periodic Classification of Element, Democracy, political parties (full page) and Challenges to Democracy from class 10th textbook to reduce the content load on students in view of the COVID-19 pandemic:,” ANI has quoted NCERT as saying.
