Resonance -a premier coaching institute for IIT-JEE

Resonance -a premier coaching institute for IIT-JEE has been guiding the students to achieve their dream of being an IITian since 2001.The uncompromising preparation for beginners at Resonance for IIT-JEE is noteworthy.Overwhelming response from the students who showed interest and faith in the quality of education provided by our highly qualified and experienced faculties have helped us to serve the society better.The institute was named as Resonance with the concept to enhance the benefits of teaching upto the greatest level of satisfaction of students and to bring them in the frequency band of teacher so that the phenomenon of resonance becomes a reality.

In the words of Mr.R.K.Verma(Chairman------Resonance,Kota,Rajasthan)--------"IIT" - a dream every Science-Maths student wants to accomplish.When you aspire to attain greater heights in your life you ought to have few characteristics like self confidence,right attitude for achieving the goal and determination dedication to excel in your desired ambition.Apart from having inherent talent and "never say die" attitude,one needs to get the proper guidance to reach the pinnacle of success.

We at Resonance believe that we need to develop strong moral values and ethics along with the subject knowledge among the students which will make them a responcible citizen of our country.Resonance has always taken an opportunity of having a pleasure of rewarding high performers and acknowledging their merits.Aspirants who have exhibited applaudable performance in their previous examinations are accredited through the scholorships being given by Resonance.
