For opening a coaching class a teacher has to have wisdom regarding that particular subject rather having bookish knowledge.With the help of traditional year by year tested notes it has become so easy to get good marks in exam but this is not enough to have a concrete knowledge over that subject.I mean to say a teacher has to taught in such a manner so that students start loving that subject because LOVE is such a stimulator which itself acts like a engine in order to bring wisdom.Moreover this is applicable for each & every field. As far as my concern value less education can only creates ROBOT which would never be granted or considered for the betterment of society.
