IGCSE OCR 附加数学（0606）考纲正在为2026年考试季进行更新，带来了新的挑战与侧重点。对目标高分的学生而言，提前掌握这些变化至关重要。本文将剖析考纲关键更新、评估方式转变及主题趋势，帮助你制定高效的备考策略。
1. Updated Syllabus Overview for 2026 | 2026年考纲更新概览
The 2026 series marks the second full cycle of the revised syllabus launched in 2025. Minor refinements continue, particularly in clarifying command words and adding contextual problem-solving examples in calculus and statistics. The overall content remains close to previous years but with a sharper focus on mathematical reasoning and modelling.
2026年考试是2025年启动的修订版考纲的第二个完整周期。考纲仍在进行微调，特别是在阐明指令词，并在微积分和统计部分增加了更多背景化的问题解决示例。整体内容与往年相近，但对数学推理与建模的侧重更为明显。
The syllabus document now explicitly links each topic to assessment objectives (AOs), making it easier for teachers and students to understand which skills will be tested. Additionally, formula sheets remain unchanged for paper 1 and paper 2, with the same booklet provided in examinations.
考纲文件如今将各个主题明确地与评估目标（AO）挂钩，这让师生更容易理解哪些技能会被考查。此外，试卷1和试卷2的公式表保持不变，考试中仍会提供同样的公式手册。
2. Changes in Assessment Structure | 评估结构的变化
OCR Additional Mathematics (0606) still comprises two written papers, each lasting 2 hours and worth 50% of the total mark. Paper 1 (Non‑calculator) and Paper 2 (Calculator) retain their roles, but the distribution of question styles has been adjusted. Paper 1 now features a greater proportion of short‑form, structured questions that probe fluency, while Paper 2 includes more extended problem‑solving tasks requiring strategic calculator use.
OCR 附加数学（0606）仍包含两份笔试试卷，各两小时，各占总分的50%。试卷1（不可使用计算器）和试卷2（可使用计算器）的定位不变，但题目类型的分布有所调整。试卷1如今包含更多短小的结构化问题，以考查熟练度；试卷2则包含更多需要策略性使用计算器的拓展型问题解决任务。
| Feature | Paper 1 (Non‑calculator) | Paper 2 (Calculator) |
|---|---|---|
| Duration | 2 hours | 2 hours |
| Marks | 80 | 80 |
| Question emphasis | Fluency, algebraic manipulation, exact values | Modelling, graphical analysis, iterative methods |
What does this mean for you? You must now practise mental arithmetic and quick algebraic simplification intensively for Paper 1, while learning to use the calculator not just for computation but to explore functions numerically and verify results.
这对你意味着什么？现在你必须为试卷1大量练习心算和快速代数化简，同时学会使用计算器不仅为了计算，更为了数值探索函数并验证结果。
3. Content Revisions: What’s New and Removed | 内容修订：新增与删除
For 2026, the syllabus has trimmed some legacy content to make room for more applied statistics and iterative reasoning. Topics such as loci in the complex plane and obscure trigonometric identities have been softened, while sequences and series now explicitly include modelling with arithmetic and geometric progressions in financial and scientific contexts.
到2026年，考纲删减了一些传统内容，为更多应用统计与迭代推理腾出空间。复平面上的轨迹以及一些生僻三角恒等式等主题的要求有所降低，而数列与级数明确纳入了金融和科学情景中基于等差和等比数列的建模。
A new focus area is ‘rate of change and differential equations in context’, where students must set up simple first‑order differential equations from verbal descriptions and solve them using separation of variables. This appears in Paper 2, building on core calculus skills.
一个新的重点是“情境中的变化率与微分方程”，学生需要根据文字描述建立简单的一阶微分方程，并用分离变量法求解。这部分出现在试卷2中，建立在核心微积分技能之上。
The following table summarises the most notable content shifts:
下表总结了最显著的内容变化：
| Topic area | Reduced emphasis | Increased emphasis |
|---|---|---|
| Complex numbers | Loci in the Argand diagram | Using de Moivre’s theorem for trig identities |
| Trigonometry | Excessive proving of identities | Solving equations in context, harmonic form |
| Calculus | Lengthy algebraic integration by parts | Differential equations, optimisation |
| Statistics | Manual mean/variance calculations | Binomial and normal distribution modelling |
4. Non‑calculator Paper Challenges | 非计算器试卷的挑战
Paper 1 demands strong mental agility. You cannot rely on a calculator to simplify surds, evaluate trigonometric exact values, or expand binomial expressions. The 2026 trend shows a rise in questions requiring exact logarithmic values and manipulation of natural logs, such as solving e2x ─ 3ex + 2 = 0 by treating it as a quadratic.
试卷1对大脑灵活性要求很高。你不能依赖计算器来化简根式、求三角函数的精确值或展开二项式。2026年的趋势显示，要求精确对数值和对自然对数处理的问题增多了，例如通过看作二次方程解 e2x ─ 3ex + 2 = 0。
Additionally, marks are often lost on implicit differentiation of equations like x² + y² = 25, where candidates forget to apply the chain rule to y. Practising step‑by‑step algebraic reasoning without the calculator’s verification is critical.
此外，学生常常在求 x² + y² = 25 等方程的隐微分时丢分，因为忘记对 y 应用链式法则。在无法用计算器验证的情况下，练习逐步的代数推理至关重要。
Start early by creating a ‘non‑calculator drill’ routine: review all exact trigonometric ratios (e.g. sin 30° = 1/2, cos 45° = √2/2), recall laws of indices, and practise solving linear inequalities with fraction coefficients. Time pressure on Paper 1 is increasing, so speed and accuracy go hand in hand.
尽早建立“非计算器专项训练”习惯：复习所有精确三角比（如 sin 30° = 1/2，cos 45° = √2/2），回忆指数定律，并练习解含有分数系数的线性不等式。试卷1的时间压力在增加，因此速度与准确性缺一不可。
5. Calculus: Deepening Application and Techniques | 微积分：深化应用与技巧
Calculus remains the backbone of the qualification. In 2026, there is a noticeable move from mechanical differentiation/integration towards interpreting gradient functions and area under a curve in real‑world models. You must be comfortable with the second derivative test for maxima and minima, and understand how to justify why a stationary point is a maximum, minimum or point of inflection.
微积分仍是该资格考试的支柱。2026年，有一个明显变化，即从机械的求导/积分转向在真实模型中解读梯度函数和曲线下面积。你必须熟练掌握用二阶导数检验极值点，并知道如何论证为什么驻点是极大值、极小值或拐点。
Kinematics problems now frequently combine integration of velocity vectors to find displacement, requiring a solid grasp of constant acceleration formulas and vector magnitude. A typical question may give velocity v = (2t)i + (3t² ─ 1)j and ask for the distance travelled between t = 1 and t = 3.
运动学问题如今经常结合速度向量的积分来求位移，这需要扎实掌握匀加速公式和向量模长。典型题目可能给出速度 v = (2t)i + (3t² ─ 1)j，要求 t = 1 到 t = 3 之间经过的路程。
Moreover, differential equations cropping up in Paper 2 are strictly first‑order and separable. For instance, given dP/dt = kP and initial conditions, setting up the model and solving for P is a high‑tariff skill. Practise converting real‑world rates into differential notation.
此外，试卷2中出现的微分方程严格限于一阶可分离类型。例如，已知 dP/dt = kP 和初始条件，建立模型并解出 P 是一项高分值技能。练习将现实变化率转化为微分符号。
6. Vectors and Matrices in Focus | 重点看向量与矩阵
Vectors and matrices are receiving renewed attention. While matrix transformations are no longer examined as standalone topics, they are embedded within geometric proofs and simultaneous equations. You will still need to multiply matrices of up to order 2 × 2 and find determinants and inverses, but the context might involve mapping points under a transformation and finding area scale factors.
向量与矩阵重新受到关注。虽然矩阵变换不再作为独立专题考查，但它们已嵌入几何证明和联立方程组中。你仍然需要做 2 × 2 以下的矩阵乘法、求行列式和逆矩阵，但情景可能涉及点在某变换下的映射以及求面积放大因子。
For vectors, the syllabus emphasises the use of position vectors and the vector equation of a line in 2D. Expect questions that blend vector geometry with trigonometry, such as finding the angle between two lines using the dot product. The formula a • b = |a||b| cos θ must be at your fingertips.
向量方面，考纲强调位置向量的运用和二维中直线的向量方程。预期会有融合向量几何与三角的问题，比如利用点积求两直线间的夹角。公式 a • b = |a||b| cos θ 你必须烂熟于心。
Common pitfalls include confusing vectors with coordinates and failing to interpret parallel vectors correctly. Remember, if vectors p and q are parallel, then p = kq for some scalar k. Practise writing clear vector solutions, as marking schemes reward notation precision.
常见陷阱包括混淆向量与坐标，以及未能正确解释平行向量。记住，若向量 p 与 q 平行，则存在标量 k 使得 p = kq。练习书写清晰的向量解题过程，因为评分标准会奖励符号的精确性。
7. Probability and Combinations: A Growing Emphasis | 概率与组合：日益重视
The statistics and probability component has grown in weighting. Beyond tree diagrams and basic conditional probability, you now need to apply permutations and combinations to probability scenarios with identical objects and constraints. Questions often ask for the number of ways to arrange letters in a word, followed by finding the probability that two specific letters are adjacent.
统计与概率部分的权重有所增加。除了树状图与基本条件概率，你现在需要在包含相同物件和限制条件的概率情境中应用排列与组合。题目常会问某个单词的字母排列方式有多少种，然后求某两个特定字母相邻的概率。
The binomial distribution is now firmly embedded, with the requirement to calculate probabilities, expected values, and interpret results. The normal distribution appears as a model for continuous data, but you will use the standardised variable z = (x ─ μ)/σ and reverse table look‑up. Calculators with statistical functions are allowed in Paper 2, but you must show clear working to gain method marks.
二项分布如今被牢牢嵌入考纲，要求计算概率、期望值并解释结果。正态分布作为连续数据模型出现，但你将使用标准化变量 z = (x ─ μ)/σ 以及反向查表。试卷2允许使用带统计功能的计算器，但你必须展示清晰步骤以获得过程分。
Also, discrete random variables and their expectation E(X) and variance Var(X) are tested, often in combination with sums and multiples of variables. The linearity rule E(aX + b) = aE(X) + b is crucial.
此外，离散随机变量及其期望 E(X) 和方差 Var(X) 也会考查，常与变量的加和与倍数结合。线性法则 E(aX + b) = aE(X) + b 至关重要。
8. Trigonometry in Context | 情境中的三角学
Trigonometry questions are becoming more contextualised. You might model the height of a Ferris wheel using a sine function, or solve for angles in navigation problems using the sine and cosine rules. The identity sin² θ + cos² θ = 1 and the compound‑angle formulas are tested via practical applications rather than abstract proofs.
三角学问题正变得越来越情境化。你可能要用正弦函数为摩天轮的高度建模，或者在航海问题中用正弦定理和余弦定理求解角度。恒等式 sin² θ + cos² θ = 1 以及复合角公式常常通过实际应用来考查，而非抽象证明。
In particular, converting between the form a cos θ + b sin θ and R cos(θ ± α) or R sin(θ ± α) is heavily examined. You must be confident in finding R and α exactly, often using R = √(a² + b²) and α = arctan(b/a) with correct quadrant selection. Paper 1 will expect these exact values without a calculator.
尤其是，将 a cos θ + b sin θ 转化为 R cos(θ ± α) 或 R sin(θ ± α) 的形式会被重点考查。你必须能够自信地求出 R 与精确的 α，通常使用 R = √(a² + b²) 和 α = arctan(b/a) 并正确选择象限。试卷1会要求在不使用计算器的情况下得到这些精确值。
Another trend is linking trigonometric equations to calculus. For example, finding the maximum of y = 2 sin x + cos 2x over a given interval, demanding differentiation, double‑angle identities, and solving sin x cos x = …
另一趋势是将三角方程与微积分联系起来。例如，求 y = 2 sin x + cos 2x 在给定区间上的最大值，这需要求导、使用二倍角公式并解出 sin x cos x = …
9. Problem‑solving and Modelling Skills | 问题解决与建模技能
The 2026 papers place a premium on mathematical modelling. The exam will present unfamiliar contexts—such as bacterial growth, radioactive decay, or economic cost functions—and ask you to interpret the parameters. This tests not just your algebraic ability but your capacity to translate between real‑world language and mathematical expressions.
2026年的试卷更加看重数学建模。试卷会给出诸如细菌生长、放射性衰变或经济成本函数等陌生情境，并要求你解释参数。这不仅考查代数能力，还考查你在现实语言与数学表达式之间转换的能力。
Examiners’ reports from recent series show that candidates often struggle to extract the relevant equation from a word problem. Practise by annotating questions: underline numerical values, circle the quantity to be found, and sketch a graph or diagram before diving into algebra.
近几次考试的考官报告显示，考生往往难以从文字题中提取出相关方程。通过批注问题来加以练习：划出数值，圈出待求量，并在开始代数运算之前快速勾画一个图像或示意图。
For Paper 2, iterative methods like the Newton‑Raphson process appear, requiring the formula xₙ₊₁ = xₙ ─ f(xₙ)/f'(xₙ). Make sure you can differentiate the given function accurately and choose a sensible starting value. The exam might ask you to perform two iterations and then comment on the approximate root’s accuracy.
试卷2中会出现如牛顿-拉夫森法等迭代法的题目，需要使用公式 xₙ₊₁ = xₙ ─ f(xₙ)/f'(xₙ)。确保你能准确地对给定函数求导，并选择合理的初始值。考试可能会要求进行两次迭代，然后评论近似根的精确度。
10. Trends in Grade Boundaries and Performance | 分数线趋向与考生表现
Analysis of the post‑pandemic series indicates that grade boundaries for grades 7, 8, and 9 in Additional Mathematics have stabilised at relatively high levels. To achieve a grade 9, candidates typically need around 75—80% of total marks, though this varies. The 2026 thresholds are expected to remain similar, rewarding depth of understanding over rote memorisation.
疫情后考试系列的分析表明，附加数学中7、8、9等级的分数线已稳定在较高水平。要获得9级，考生通常需要取得总分的大约75—80%，尽管这一比例会有所波动。2026年的分数线预计将保持类似趋势，青睐深度理解而非死记硬背。
Common mistakes that drag marks down include incomplete simplification, not stating units in modelling questions, and omitting the constant of integration ‘+c’. Examiner feedback consistently emphasises the need for clear, logical steps; a correct final answer without working may lose full marks if the method is not obvious.
拖低分数的常见错误包括未彻底化简、在建模题中漏写单位，以及遗漏积分常数 “+c”。考官反馈一贯强调逻辑清晰的步骤；若最终答案正确但无推导过程且方法不明显，可能拿不到满分。
Furthermore, students often mishandle the ‘hence or otherwise’ questions—using the ‘hence’ path is usually faster and checks your understanding of the previous part. The 2026 papers are likely to include more ‘show that’ prompts, which require rigorous logical progression.
此外，学生经常处理不好“因而或用其他方法”这类问题——使用“因而”路径通常更快，并能检验你对前一小题的理解。2026年试卷可能会包含更多“证明”类的提示，这需要严谨的逻辑推导。
11. Effective Preparation Strategies for 2026 | 2026有效备考策略
Build a revision timetable that alternates between Paper 1 and Paper 2 skills. For Paper 1, focus on algebraic fluency and exact value drills. For Paper 2, work on graph sketching, calculator exploration, and modelling case studies. Use past papers from 2023 onward to align with the current syllabus style, and carefully review mark schemes to absorb the expected notation.
制定一份在试卷1与试卷2技能之间交替的复习时间表。试卷1要专注于代数熟练度和精确值训练。试卷2则要夯实图像绘制、计算器探索以及建模案例研究。使用2023年及之后的历年真题以匹配当前考纲风格，并仔细研读评分标准以吸收预期的符号表达。
Incorporate active recall techniques: create flashcards for trigonometric exact values, common derivatives, and integrals; summarise each topic in a mind map linking concepts. Teaching a peer is one of the most effective ways to solidify your own understanding.
融入主动回忆技巧：制作抽认卡记忆三角精确值、常见导数和积分；用思维导图概括每个主题以连接概念。向同伴讲解是巩固自身理解最有效的方式之一。
Do not underestimate the importance of wellbeing: get enough sleep before the exam, as Paper 1 requires sustained concentration. Time yourself strictly during mock exams, including reading time, to build mental stamina.
不要低估身心状态的重要性：考前保证充足睡眠，因为试卷1需要持久的专注。模拟考时要严格计时，包括阅读时间，以培养应考的心理耐力。
