I think this is a very useful course in afterschool. The teacher did not just teach maths like how the teachers in my school do. Instead, he used some clever ways, and made everything simple! I finally understand what I have been learning. It is out of my expectation, that the teacher even taught some ways to revise and prepare for DSE!
