I have been a private tutor since 2009. I specialize in mathematics and have helped my J2 students who used to get F grade score A in A'levels.
When I teach, I emphasize on the rationale of the concepts rather than letting my students memorize blindly. When my students ask me why they cannot get the answers, I am able to tell them where their thinking processes go wrong.
I am also patient. I like the feeling of when I help others and enlighten them. I believe everybody has the potential to do well in academics. The most important thing is to understand, but not to memorize.
