EXUN, (the computer club at Delhi Public School, R K Puram), stands for "Experts Unlimited". Our motto is "We not I" , which in essence means that we believe in team spirit. EXUN was started in 1992 by the Head of Department, Computer Science, Mr. Mukesh Kumar and a small group of talented students. It is today a 70+ member organisation with its members standing out in various fields like computer programming, computer quizzing, and Web Designing.

Exun members form an elite team of computer enthusiasts of all ages. They have represented the school in various computer symposia in India and around the world. They have been actively involved in activities like web page designing, software development and attending inter-school competitions. They have won several awards at various symposiums, excelling in nearly all of them and securing top positions.

Having represented the school in various computing symposia in India and around the world, the club also hosts the Delhi Public School R K Puram annual computer symposium "Exun". Eleven such symposiums have taken place and have been a grand success. In 2009 Exun is holding its 14th Annual Symposium and we're sure that like the previous 13, this one too is going to be a major success!
