At the beginning of the new school year, students in G11 and G12 have already started their intense study of A-level Mathematics (9709). This course is divided into five parts, which are Pure Numbers 1, Pure Numbers 3, Mechanics, Statistics 1, and Statistics 2. Among them, pure number 1, pure number 3 and statistics 1 are compulsory, and students need to choose one of them in statistics 2 and mechanics. Usually the pure number 1 and statistical 1 are completed in the first year, the so-called AS phase. In the second year, A2 phase, students will complete the remaining two courses.
