Muslims prefer to send their kids to Madarsa when primary education in India is free for all because Madrasas are also a kind of school and education is free there. However, there is class distinction among people following the same religion. A middle class educated Muslim will most probably send their kids to a secular school. However, if the quality of education in Madrasa is improved, they would become popular like convent or missionary schools where people from all religions send their children to study.
