when classes are on ZOOM, Why have Exams in room?

As Told by the respected teachers of Seth M.R. Jaipuria School Lucknow, Children Are not able to score high marks in offline tests. According to us when a good student is scoring low grades, instead of conducting more offline tests teachers should should prefer conducting offline classes so that much of what has been taught online which was not understood by most of the student body ( reason for scoring low marks ) is cleared within the limited time frame i.e. before finals. There are various issues being faced by the students(from the teacher's side) which includes low camera quality/positioning of the teachers themselves, low network bandwith of the teacher, hazy videos and overall there is a big difference in interacting and attending offline classes than sitting on a technical device with earphones and watching a particular video on repeat.We know that teachers are trying there best but still its not an ideal interactive online LIVE class.
