Fortunately, during the mid-term of Form 4, our school started an Excellence Advancement Program after school, in which our school hired extra teachers for each specific subject. I was one of the few students who could join in. While I was there, we did more practice and review of what we had learned. With the help of these classes after school, I found obvious improvement in my weaker subjects.
