Weichang Lai

National University of Singapore B.Sc (Hons) Physics

Hi, my name is Weichang Lai. I am an Adjunct Lecturer teaching Engineering Mathematics / Physics at Nanyang Polytechnic (NYP), School of Engineering. This video series is inspired partly because many of my diploma students are weak in Math and they have no place to turn to when they want to strengthen their foundation. If you are a Singapore student who did not manage to follow a specific topic in class, or a student outside Singapore who wants to be exposed to Singapore Math, feel free to follow my courses too. I will put the entire O-Levels syllabus online so that anyone can learn from these videos. I am also the co-founder of ManyTutors.
