In the midst of the lockdown most of the schools have started online classes on apps . Teachers are taking online classes regularly and most of the students are attending in it enthusiastically but while taking online classes some of the students change their name and they disturb the whole class as well as teacher by sending lewd messages and playing music during the class . On Tuesday, I was attending my physics class , a student entered the class by changing his or her name and started showing toilet seat while students were being taught by teacher in class. They distract the whole class . It is very difficult to identify these student for teachers . It is the responsibility of the parents that their child is attending the classes sincerely or not . They should keep an eye on their children .
