Are you preparing for CIE AS Level Mathematics in 2026? The syllabus has undergone its most significant redesign in years, and every Year 12 student needs to understand what’s changed. From the removal of a dedicated Pure Mathematics 2 paper to a stronger emphasis on applied skills and real-world problem solving, the 2025–2027 syllabus (fully in use by 2026) reshapes both the structure and the nature of assessment. This guide walks you through all the key changes, emerging trends, and practical strategies to help you succeed in the 2026 exam series.
你正在备战2026年CIE AS数学吗？这份教学大纲经历了近年来最大规模的重构，每一位12年级学生都必须了解这些变化。从取消独立的纯数学2试卷，到更加强调应用技能和真实情境下的解题能力，2025–2027年新版大纲（2026年全面实施）重新塑造了考试的结构与性质。本文将带你逐一梳理所有关键变化、新趋势，并提供实用的备考策略，助你在2026年考试中脱颖而出。
1. The 2025–2027 Syllabus: What Stays and What Goes | 2025–2027年大纲：保留什么，取消什么
The Mathematics 9709 syllabus was revised for first teaching from 2025, meaning the 2026 exam series will be the first full cycle free of legacy arrangements. The most headline-grabbing change is the retirement of the standalone Pure Mathematics 2 paper (Paper 2 in the old structure). Instead, AS Mathematics now consists of only one compulsory pure paper – Paper 1: Pure Mathematics 1 – plus a choice between Mechanics (Paper 4) and Probability & Statistics 1 (Paper 5) as the application component. At A2 level, the pure component remains Paper 3: Pure Mathematics 3, while students must take two applied papers from Mechanics, Probability & Statistics 1 and Probability & Statistics 2.
数学9709大纲于2025年首次教学，意味着2026年的考试系列将是彻底告别旧制后的首个完整周期。最引人瞩目的变化，就是取消了独立的纯数学2试卷（旧结构中的Paper 2）。现在，AS数学只包含一张必修的纯数试卷——Paper 1：Pure Mathematics 1，外加从力学（Paper 4）或概率与统计1（Paper 5）中二选一的应用卷。而在A2阶段，纯数部分仍然是Paper 3：Pure Mathematics 3，学生还需从力学、概率与统计1和概率与统计2中选择两份应用试卷。
2. Restructured AS Assessment: One Pure Paper, One Applied Choice | 重构的AS考核：一张纯数卷 + 一张应用卷
Under the new regulations, a Year 12 student completing AS Mathematics will sit Paper 1 and either Paper 4 (Mechanics) or Paper 5 (Probability & Statistics 1). This replaces the old combination of Paper 1 and Paper 2 (both pure), eliminating the second pure exam and giving applied mathematics a fixed weight at AS. The rationale is to connect mathematical techniques with tangible contexts earlier, encouraging students to see mathematics as a tool rather than an abstract construct. The pure paper carries 60% of the AS result and the applied paper 40%, shifting the balance of skills tested.
按照新规，完成AS数学的12年级学生将参加Paper 1以及Paper 4（力学）或Paper 5（概率与统计1）中的一卷。这取代了过去Paper 1加Paper 2（两张纯数卷）的组合，取消了第二场纯数考试，使应用数学在AS阶段占据了固定权重。其目的是尽早将数学技巧与具体情境联系起来，鼓励学生将数学视为工具而非抽象构造。纯数卷占AS总成绩的60%，应用卷占40%，从而改变了所考查技能的配比。
3. The Discontinuation of Pure Mathematics 2: Content Redistribution | 纯数学2的取消：知识点重新分配
The old Pure Mathematics 2 paper covered topics such as laws of logarithms, advanced trigonometry, further algebra, sequences and series, and an introduction to calculus techniques. With its removal, many of these topics have been absorbed into Paper 1 (Pure 1) or transferred to Paper 3 (Pure 3). For instance, the logarithmic and exponential functions now appear in Paper 1, while some of the more intricate integration techniques have moved to Paper 3. This redistribution means Year 12 learners face a more demanding Pure 1 syllabus, as they must master a broader range of pure concepts within a single paper. A closer look at the syllabus shows that the overall depth of pure content at AS has not reduced – the same core ideas are simply taught and examined earlier.
旧版的纯数学2涵盖了对数运算律、进阶三角学、更高层次的代数、数列与级数，以及微积分初步等内容。随着该卷取消，这些知识点大多被并入Paper 1（纯数1），或移入Paper 3（纯数3）。例如，指数与对数函数现在出现在Paper 1中，而部分更复杂的积分技巧则移至Paper 3。这种重新分配意味着12年级学生将面对一份更具挑战性的纯数1大纲，因为他们必须在一张试卷内掌握更广泛的纯数概念。细看大纲可以发现，AS阶段纯数的总深度并未降低——同样的核心思想只不过在教学上提前了，在考查上集中了。
4. A2 Level Focus: Pure 3 and Advanced Applications | A2阶段的焦点：纯数3与高级应用
For students continuing to A Level, Paper 3 remains the cornerstone of advanced pure mathematics. It covers complex numbers, further calculus (including integration by parts), vectors, differential equations, and deeper algebraic methods. The applied side now requires two papers from Papers 4, 5 and 6, with the most common combination being Mechanics (Paper 4) and Probability & Statistics 1 (Paper 5). However, schools may also offer Statistics 2 (Paper 6) for students aiming for degrees in data science or economics. This structure gives a more sustained focus on applications across the two-year course, and students planning their A2 journey should decide early which applied pathway best supports their future ambitions.
对于继续攻读完整A Level的学生，Paper 3仍是进阶纯数的基石。它涵盖复数、深入微积分（包括分部积分）、向量、微分方程以及更深层次的代数方法。应用层面则需要从Paper 4、5、6中选取两份试卷，最常见的组合是力学（Paper 4）和概率与统计1（Paper 5）。不过，针对未来希望攻读数据科学或经济学的学生，学校也可能提供统计2（Paper 6）。这一结构使得在两年的课程中能更持续地侧重应用，规划A2旅程的学生应尽早决定哪条应用路径最契合自己的抱负。
5. Updated Weighting and Timing: Numbers You Need to Know | 更新的权重与考试时长：你需要掌握的关键数据
The mark allocations and durations have been refined to match the new paper compositions. Understanding these numbers is essential for time management and revision planning.
分值分配和考试时长已根据新的试卷构成进行了调整。熟悉这些数字，对时间管理和复习规划至关重要。
| Component | Duration | Marks | AS Weight | A Level Weight |
|---|---|---|---|---|
| Paper 1 – Pure Mathematics 1 | 1 hr 50 min | 75 | 60% | 30% |
| Paper 4 – Mechanics *or* Paper 5 – Probability & Statistics 1 | 1 hr 15 min | 50 | 40% | 20% (each if chosen at A Level) |
| Paper 3 – Pure Mathematics 3 (A2 only) | 1 hr 50 min | 75 | N/A | 30% |
| Additional Applied Paper (Paper 4, 5 or 6) at A2 | 1 hr 15 min | 50 | N/A | 20% |
Notice that at AS, the pure paper carries 60% of the marks, a small reduction from the 70% it previously held when two pure papers were combined. This gives applied mathematics a more substantial voice in the final grade.
请注意，在AS层面，纯数卷占60%的分数，略低于以往两张纯数卷合计时的70%。这让应用数学在最终成绩中拥有了更多话语权。
6. Emerging Trend: Application-Heavy and Contextual Questions | 新趋势：应用型与情境化题目增多
CIE has signalled a deliberate shift towards questions that require students to interpret and model real-world scenarios. In Pure 1, for example, you might encounter a problem framed around the growth of a population, asking you to form an exponential model and then differentiate to find a rate of change. In Mechanics, scenarios often involve projectiles, inclined planes, and connected particles, while Statistics papers present data from health studies, finance, or sports. The ability to move between a written context, a mathematical model, and a conclusion in words is now a core assessment objective. This trend rewards students who practise not only routine exercises but also open-ended, multi-step problems.
CIE已明确释放信号，表示题目将更多要求学生解读并建立真实世界情境的模型。例如在纯数1中，你可能会遇到一个围绕人口增长构建的问题，要求你建立指数模型，再微分求出变化率。力学试卷中，抛体、斜面和连接体情境频繁出现；统计卷则呈现健康研究、金融或体育数据。能够在文字背景、数学模型和语言结论之间自由转换，已成为核心评估目标。这趋势将回报那些不仅练习常规题型，还适应开放性的、多步骤问题的学生。
7. Calculator Requirements and Technology in the 2026 Exams | 2026年考试的计算器要求与技术运用
All candidates must have a scientific calculator with standard statistical functions (mean, standard deviation, regression). Graphical display calculators are permitted but not required, and symbolic algebra (CAS) calculators are strictly prohibited. The new syllabus places greater emphasis on using calculator features efficiently – for example, solving quadratic equations numerically, evaluating definite integrals, and performing statistical calculations quickly under timed conditions. Examiners now expect students to show clear working separately from calculator outputs, so familiarising yourself with the exact syntax and limitations of your calculator model is a practical must.
所有考生必须携带具备标准统计功能（平均值、标准差、回归分析）的科学计算器。图形计算器允许使用，但不强制要求；而符号代数（CAS）计算器则被严格禁止。新大纲更加强调高效利用计算器的功能——例如在限时条件下，数值求解二次方程、计算定积分、快速完成统计运算。考官现在要求考生将解题步骤与计算器输出清晰地分开呈现，因此熟悉自己计算器型号的具体语法和局限，是务实的必修课。
8. Skills and Assessment Objectives: What the Examiners Want | 技能与评估目标：考官想要什么
The assessment objectives have been refined into three broad categories: AO1 – Knowledge and technique (routine manipulation, recall of facts), AO2 – Analysis and reasoning (constructing and following logical arguments, problem-solving), and AO3 – Interpretation and communication (modelling, interpreting solutions in context). In the 2026 exams, AO2 and AO3 carry greater weight than before, especially inside the applied papers. This means that simply memorising formulae and procedures will not guarantee a high grade; students must demonstrate flexible thinking and the ability to explain their reasoning in clear, mathematical language. Practice should therefore include writing concise justifications and evaluating the validity of models.
评估目标经过细化，分为三大类：AO1——知识与技巧（常规运算、知识点再现），AO2——分析与推理（构建并遵循逻辑论证、解决问题），以及AO3——解释与交流（建模、在情境中阐释结果）。在2026年考试中，AO2和AO3的权重高于以往，特别在应用卷中更为显著。这意味着仅靠背诵公式和步骤无法保证高分；学生必须展现灵活思维，并能用清晰的数学语言解释推理过程。因此，备考练习中应当包括撰写简洁的论证句和评判模型的有效性。
9. Preparing for 2026: A Strategic Year 12 Study Plan | 备战2026：一份策略性的12年级学习计划
Start by downloading the latest 2025–2027 syllabus and the specimen papers form the CIE website. Map each topic to the relevant paper and create a revision checklist. Dedicate the first term to mastering Pure 1 foundations – functions, coordinate geometry, trigonometry, differentiation, and integration are the high-yield pillars. Then, systematically work through your chosen applied module, alternating between content learning and past-paper style questions. Schedule timed mock sessions that exactly mirror the new paper durations: 1 hour 50 minutes for Pure 1 and 1 hour 15 minutes for the applied paper. Use examiner reports from the first new-style sittings (likely 2025 papers become available) to identify common mistakes. Finally, maintain a ‘mathematical vocabulary’ notebook where you record phrases used in model answers for interpretation questions – this will sharpen your AO3 performance.
首先，从CIE官网下载最新的2025–2027年大纲和样卷。将每个主题映射到相应试卷，制作一份复习清单。第一学期集中攻克纯数1的基础——函数、坐标几何、三角学、微分和积分是需要重点掌握的支柱。接着，系统地学习你选择的应用模块，在内容学习与真题风格练习之间交替推进。安排计时的模拟考，完全按照新试卷的时长：纯数1为1小时50分钟，应用卷为1小时15分钟。利用新制首次考试的考官报告（预计2025年试卷资源会陆续放出）识别常见错误。最后，准备一本“数学词汇”笔记本，记录高分范文中用于解释型问题的表达，这将大幅提升你的AO3表现。
10. Common Pitfalls and How to Avoid Them | 常见误区与应对方法
One of the biggest mistakes Year 12 students make is treating the applied paper as less important because it carries only 40% of AS marks. In reality, the applied paper often differentiates top performers because its interpretation demands cannot be compensated by pure computational speed. Other pitfalls include neglecting to practise the Pure 1 topics that were formerly in Pure 2, such as extended logarithm and exponential equations, and relying too heavily on calculator step-by-step solvers without showing the underlying working. Additionally, many candidates lose marks by not linking their final answer back to the context of the question, especially in Mechanics and Statistics. To avoid these traps, always finish a problem by writing a concluding sentence that references the original scenario.
12年级学生最大的误区之一，是认为应用卷仅占AS成绩的40%而无足轻重。实际上，应用卷往往是拉开顶尖学生差距的关键，因为它对解读能力的要求无法靠纯计算速度来弥补。其他常见陷阱包括忽略那些以前在纯数2中考查、现在并入纯数1的知识点（如扩展的对数和指数方程），以及过度依赖计算器的分步求解功能却未写出基本的推导过程。此外，许多考生因为没有将最终答案与题目情境联系起来而失分，在力学和统计中尤甚。要避开这些陷阱，请务必在每题作答末尾写上一句回扣原情境的总结语。
