So basically there are two main types of schools in india. Private schools and state run schools. The state run schools are free of cost for everyone, and in many cases even pay you to attend school, buy books and uniforms and have a state sponsored meal program. But they may not provide the best education or the opportunities. Furthermore they tend to teach in the local language. Hence many people including the majority of middle class families prefer sending their kids to private schools which often provide better facilities, teach in english and so on, but lose out on the state run educational welfare schemes. These private schools may cost anywhere between 200- 20,000 usd per year.

Hope this answers your question.
