I, am a final year B.Sc.Statistics student. I was a subject matter expert (Statistics and Probability) in Chegg India for three months. Because of a student, I, am always touch with mathematics and statistics. In some times, I spent my free times with lower class students especially 8-10 grade students for tutoring maths them. I conducted my session purely interactive in manner. First of all I gave them an outlier what to study, and I explain the topics in detail. I focused on problem solving. I will worked out more than 10 questions from each topic in my class.
You can ask me any kind of doubts on our topic. I, am ready to solve your problems and clear your doubts. I will interact with you on the basis text books. Mainly, I am expecting through this to improve my tutoring quality and experience. And I can improve my subject knowledge through tutoring. "The best way of learning is teaching".
