Ranchi: The Jharkhand government has given its nod to start physical classes for colleges from Thursday but on Day 1, many constituent and affiliated colleges of the University of Ranchi have adopted both offline and online classes to avoid crowding on campus and ensure Covid-19 safety rules. Earlier, the registrar of the university had issued a notification to all constituent and affiliated colleges to open their campus from March 1 after carrying out cleaning and sanitization work for two days. The colleges have also been directed to follow the University Grants Commission (UGC) guidelines during the classes. However, the Ram Lakhan Singh College here has started offline classes and continued with the live streaming of the classes for those who want to attend them online.
