KOTA, India (Reuters) – With a sprawling five-acre campus, 10,000 students and state-of-the-art LCD projectors in its lecture rooms, Bansal Classes is bigger and slicker than most schools in India.

But the institution, now a landmark in Kota, a city in the desert state of Rajasthan, is neither a school nor a college. It is the jewel in the crown of India’s private coaching industry, a $6.4 billion business that exacerbates the social divide.
