I started tutoring right from my sophomore undergraduate year. I teach not only from a career or professional perspective but also for fun. Initially, I taught maths and physics to some high school students who scored very well in their exams and that gave me the confidence to further hone my teaching skills. Right after completing college I chose to teach over normal engineering job and joined smart educational tutorials as a tutor. Here apart from teaching normal STEM subjects, I used to conduct demonstration classes to build student interests in science and engineering. I taught about a year on this tuition center. To expand my sphere of interaction with students, I started looking for online tutoring opportunities and got selected as subject matter expert on chegg.com. Here my job is to answer the queries posted by undergraduate electrical engineering students. So far I have an experience of teaching students right from high school to undergraduates.
