That is the one I am looking forward to. Indian history today is freedom struggle - mughal empire - freedom struggle - mughal empire - gandhi - nehru - akbar. Is all.
Indian history is long overdue for a huge revamp. We need more balanced views of the independence movement. We need greater exposure to non-Delhi kingdoms that shaped the major parts of the country. We need history of the period between 1947 - 2000.
World history needs to be taught from a non-western lens too. India needs to learn about the East & Africa, just as much as the west. This is especially valid because Indians have closer historic ties to South East Asia and diaspora in places like Guyana, the Caribbean and Africa. With the advent of population genomics, we must include findings about Sub-continental pre-history that are more scientific than the idle musings of some 18th century white guy.
PS: good summary of the Indian educational system. As you correctly pointed out, western intuitions about education do not transfer well to the Indian system.
