Jai Hind everybody, In the difficult time of Covid 19 the classes are being taught by online mode. The scenerio looks to continue as it is for the time to come. Complaints of non hearing of the audio, low picture quality etc. are continuously coming. For the effective transmission of the lectures, the students as well as the teachers are being given some suggestions. 1.All the students must switch off their mic and video during the lecture, it will enhance the quality of audio/video many fold and you could listen/understand clearly. 2.Mic may be switch on only to ask question. 3.Teachers should also observe the same and must ask everybody to switch off the 🎤mic/🎥video in the begining. By complying to these simple steps we can improve our online classes and make them more useful. With best wishes ADESH KUMAR
