Number of students in a class has been limited to 50% of total strength While students in intermediate semesters are preparing to return to campuses for the first time in months on Friday, many colleges across the State are likely to face a shortage of classrooms, and also teachers. The number of students in a class is limited to 50% of the total strength to ensure social distancing as a precaution against COVID-19. One of the solutions is to conduct classes in batches, with the room sanitised between sessions, while another is an alternate day model. T.M. Manjunath, president of the Karnataka Government College Teachers’ Association, said college managements would evaluate how many students would attend classes and then decide whether to conduct lectures in batches.
