In my class, I would like to help my students with the necessary tutoring and proper direction towards understanding natural science subjects such as Physics, Chemistry, and Mathematics for students at IB level, high school level, and school level. I am familiar with the European School system, International School System, and A-level.

I myself was among the top 3s during my high school days and since then I have a great experience tutoring. I would look into problems from the student's point of view. This enables me to know where they are having difficulty and then help them study nicely.
