I am B.Tech Graduate from National Institute of Technology of 2018 batch. I used to give home tution to students in Rourkela. I also joined some local coaching institutes for delivering lectures but due to scarcity of time and stringent schedule, I was not able to continue in coaching institites but I continued to give home tution. I'm having the teaching experience of more than 3 years in teaching. I am very much passionate about sharing knowledge and experience with young student and it gives me immense pleasure when students keep improving with my little effort.
