My teaching experience started with helping my cousins with their school homework. In the 10th standard I and my friends, I used to study in groups where I helped them to clarify their doubts. This continued in college where I used to explain difficult concepts from Physics, Chemistry, Biology, and Maths. Also while pursuing engineering my friends used to come to my hostel room a few days before the exam where I helped them in clarifying their doubts in difficult numerical problems from mechanical engineering subjects like Strength of Materials, Theory of Machines and Thermodynamics. Apart from this, I have also taught some village students near our college through our social welfare cell, Avana at IIT Indore. Being a part of CAE(Computer-Aided Engineering) and Robotics club conducted various workshops for first semester students and helped them develop a genuine interest in CAD(Computer-Aided Design) and Robotics.
