I have been teaching Physics and Mathematics in a Band 1 EMI secondary school for more than 25 years. The performance of my students in various public examinations were brilliant if not excellent. I have full confidence that I am able to stimulate the learning incentives of students in Physics and Mathematics. Moreover, I have also been appointed as markers for HKALE as well as HKDSE for more than 20 years in total. Thus I am also confident that I can give very useful advices to students who aim to get good results in public examinations.
