Hi there Arim.

Hope you're having a great day.

I would like to inform you that if you are aiming for premier schools in India like for example Kendriya Vidayalaya or St Stephen's School or Loyola School.

You can expect to get admission in these schools based on merit of previous standards and most of these schools have websites where you'll get the admission form for following the admission procedure.

Hope it helps. Have a nice day.
