The cancellation of board exams and the emphasis on marks obtained in school exams for calculating final scores have made students more serious about classes, assignments and assessments, teachers of several schools said. The atmosphere in online class has changed, too, many teachers have reported. Probably goaded by parents, students appear more attentive. Advertisement Schools have also ratcheted up the pressure — the student’s video must be on all the time, no entry five minutes after class starts, a student has to respond immediately when his or her name is called out or will be marked absent, parents are being alerted via email if their ward is absent.
