I haven't found the reason yet that why we don't have teacher's in colleges which can explain everything well and we are not finding lectures or good teachers on KZbin. Even we are paying in colleges

[@ZahidaPerveen-l8e]

Because the youtube teachers know the concepts more good and they are experts
