FIITJEE Talent Support Exam (FTSE) Result 2010

(Result)

FIITJEE was created in 1992 by the vision and toil of Mr. D. K. Goel, a Mechanical Engineering Graduate from IIT Delhi. 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. Onto the way to realization of this vision, we somewhere went beyond just 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 FIITJEE training. We started changing lives. And all this was not a sheer coincidence.
