I am an experienced Mathematics and Statistics tutor with 10 years of experience teaching students and working professionals. I love teaching students who are passionate to learn subjects or wants to understand any mathematics and statistics concept at graduation or master’s level. I have worked with thousands of students in my teaching career. I have helped students deal with difficult topics and subjects like Calculus, Algebra, Discrete Mathematics, Complex analysis, Graph theory, Hypothesis testing, Probability, Statistical Inference and more. After learning from me, students have found Mathematics and Statistics not dull but a fun subject. I can handle almost all curriculum of mathematics. I did B.Sc (mathematics), M.Sc (mathematics), M.Tech (IT) and am also Gate (CS) qualified. I have worked in various college and school and also provided online tutoring to American and Canadian students. I look forward to discussing with you and make learning a meaningful and purposeful
