Mathematics ( Algebra, Matrices, Differentiation and Integration etc) and Calculus

I am 36 years old. I used to teach weak students of my class fellows when I was in Grade 8 in 2003. I used to help them in solving Mathematics questions and physics problems with focus on algebra, matrices and classical physics etc. After graduation in 2013. I started teaching part time after my engineering job and then after 13th of June 2017 I am teaching physics, mathematics, science and English. I prepare lesson plans with focus on smart objectives, class activities, student centered learning and continuous assessment of student through quizzes, individual and group work.
