DDE was created in 2008 by the vision and toil of Mr. V. K. Singh. We had a very humble beginning as a forum for IIT/JEE, with a vision to provide an ideal launch pad for serious JEE aspirants .Along the way to realization of this vision, we went beyond merely coaching for IIT/JEE. We actually started to make a difference in the way students think and approach problems. We started to develop ways to enhance students’IQ. We started to leave an indelible mark on the students who have undergone DDE-IIT/JEE training.
