Indian public education at the primary and secondary level is pathetic and most people desperately try to enroll their kids in private schools which leech hell lot of money from them. Achieving mass literacy in a country which doesn't even speak one language is a complex task which will take long time to achieve, let alone standardizing the development of skills across India. India's educational future is basically clusters of regions such as the South, West, capital region and maybe central producing talent while Bihar, Jharkhand, eastern UP, Chhattisgarh etc will have near subsaharan African levels of literacy, nutrition and skills development unfortunately. Bihar specifically has abundance of talent which will likely never get tapped.
The education at the university level is also bad outside of a couple of private engineering universities and the IITs, IIITs, IISc, NITs, AIIMS etc. For educational development, India's unbelievable diversity proved to be its worst curse!
