What should be the fees for class XI and xii physics per class in Bhubaneswar?
According to me, the best fee will be the changed study pattern of the students from rote to conceptual and being able for themselves to choose what they actually want to do after 12th ( not necessarily engineering or MBBS). Thanks.
