Under normal circumstances, CBSE releases the datesheet in December and conducts the exams in February and March. In 2019, the date sheet was released in November. However, this year CBSE might postpone the exams until April May as the schools in most States were not opened until recently. Few States closed their schools for as may as 8 months. The HRD Minister did announce that the students, parents and teachers will give their opinion in this regards and a campaign will be launched to collect their views. So it is likely that some news will be announced in the month of December and it is unlikely that the exams will be held in February or March. Having said that, it is always good to hear from the horse's mouth and so please watch out for official notification from the MHRD in this regards.
