The CBSE class 10 board exam for 2021 has been cancelled, while the class 12 board exam has been postponed due to the ongoing Covid-19 situation in India. Prime Minister Narendra Modi presided over a high-level meeting that included Union Education Minister Ramesh Pokhriyal, Principal Secretary to the Prime Minister, Cabinet Secretary, School and Higher Education Secretaries, and other top officials.
