A robust scheme of work reserves the final 8–10 weeks before the summer examination for revision. This period should include full past papers, targeted topic review based on diagnostic tests, and formula recall practice. Teachers are encouraged to integrate regular low-stakes quizzes throughout both years to reinforce memory and identify gaps early.

A typical two-year timeline is: Year 1 covers Sections 1–5 (about 30 weeks), Year 2 covers Sections 6–8 and the optional topic (about 25 weeks), and the remaining time is dedicated to mock examinations and final revision. This balanced structure ensures thorough coverage without rushing advanced topics.

典型的两年时间线为：第一年覆盖第1–5部分（约30周），第二年覆盖第6–8部分和选修主题（约25周），其余时间用于模拟考试和最终复习。这种均衡结构确保充分覆盖进度，同时不仓促推进高阶主题。
