在课堂上使用迷你白板进行快速技能检查，例如求积分因子或绘制极坐标曲线，立即暴露常见错误，如漏掉模长或积分限错误。
Implement "exam-style question breaks": every two weeks, give a 25-minute timed quiz with two or three multi-step questions drawn from past papers. This builds exam stamina and time management, while informing you about gaps in student understanding.
设置“模拟考题间歇”：每两周进行一次 25 分钟限时测验，包含两至三道来自历年真题的多步问题，培养考试耐力和时间管理，同时让你了解学生理解上的漏洞。
After each major topic, provide a diagnostic grid where students self-assess against the AQA specification points (e.g., "I can find the nth roots of a complex number and show them on an Argand diagram"). This promotes metacognition and guides revision priorities.
每个主要主题结束后，提供一个诊断网格，让学生对照 AQA 课程标准进行自我评估（例如，“我能求复数的 n 次方根并在阿干特图上表示”），促进元认知并引导复习优先顺序。

12. Revision Planning and Exam Technique | 复习规划与应试技巧
Design a revision schedule that interleaves topics rather than blocking them. For example, after revising complex numbers, assign a past paper question on polar coordinates, then a question on differential equations—this spaced retrieval improves long-term retention.
设计交错而非集中式的复习时间表。例如，复习完复数后，布置一道极坐标真题，再布置一道微分方程真题——这种间隔提取能提高长期记忆保持。
Devote specific sessions to AQA command words such as "prove", "hence", "show that", and "determine". Model how to structure a solution with clear logical flow, proper notation, and concluding statements.
专门安排课时讲解 AQA 题目的指令词，如“证明”、“由此”、“展示”和“确定”，示范如何组织具有清晰逻辑脉络、规范符号和结论陈述的解答。
Run "mock exam" clinics where you mark responses using AQA mark schemes together with the class, highlighting where marks are gained or lost, particularly for method marks. This transparency demystifies examiner expectations and boosts confidence.
举办“模拟考”门诊，与学生一起使用 AQA 评分方案批改答卷，强调得分点和失分点，尤其是方法分。这种透明化破除对考官要求的神秘感，增强信心。
