During the course of my study, I have worked as a private tutor. I have taught Maths and Physics to O'Level and A'Level students, as well as I have also taught basic engineering courses to my juniors in the university. Engineering intrigues me alot because it a world full of ideas. I have passionately taught students and this made me learn alot. Teaching algebra and basic calculus, from the very basics of it made me very patient. Therefore, I know many tricks to make your work easier for you.

My juniors are always happy from me because I help in their assignments and they are never late.
