Which is a better option for nursery admission, Salwan Public School Rajendar Nagar or Bal Bharati Public School Pusa Road? Kindly reply.

My son has been shortlisted for admission in R.S.Junior Modern School. Many people have impression that mostly the elites study in this school. Is it true? How is standard of academics & discipline? How does this school stands against Springdales, Pusa Road? Does someone have idea about fees of Modern School? Kindly advice.
