Wow, Seems like Mr Andrew Er is still so popular. I first met him like 20 years back , He was my form teacher back than. His way of teaching maths is great. It is not just about numbers , he will make it interesting but yet tricky. I remember my results are usually around the 60+ range but after he took over my class from mid of P4 i have shown great improvements and got a A* in PSLE .
