Two days after announcing Class 10 or HSLC and Class 12 or HS final exams will be held, the Assam Government on Thursday said exams will be conducted only if the Covid-19 positivity rate drops below 2 per cent. The two education boards - Board of Secondary Education Assam (SEBA) and the Assam Higher Secondary Education Council (AHSEC) - will try to hold the exams in mid-July, Chief Minister Himanta Biswa Sarma said.
