剑桥Pre-U进阶数学资格向来以其深度、严格的证明导向以及对大学数学、工程和物理学习的优异衔接而备受认可。随着2026年考季的临近，大纲、评估结构和题型风格都将迎来重要更新。这些变化旨在反映现代数学实践，强化问题解决能力，并使纯数、力学和统计各部分之间更加协调。尽早理解这些发展将为考生的备考带来决定性优势。
1. Overview of Cambridge Pre-U Further Mathematics | 剑桥Pre-U进阶数学概述
The Cambridge Pre-U Further Mathematics syllabus (9795) is a linear qualification typically taken over two years. It consists of four compulsory papers: Paper 1 (Pure Mathematics 1), Paper 2 (Pure Mathematics 2), Paper 3 (Statistics and Probability) and Paper 4 (Mechanics). The 2026 update represents the most substantial overhaul since the last major revision in 2018, with adjustments to content, assessment objectives and the permitted use of technology.
剑桥Pre-U进阶数学大纲（9795）是一门通常需要两年完成的线性资格考试。它由四份必考试卷组成：试卷一（纯数1）、试卷二（纯数2）、试卷三（统计与概率）和试卷四（力学）。2026年的更新是自2018年上一次重大修订以来规模最大的改革，涉及内容、评估目标和技术使用许可的调整。
The syllabus aims to foster mathematical thinking beyond routine procedures. Candidates are expected to construct rigorous proofs, model real‑world situations and communicate mathematical reasoning clearly. The new changes further embed these principles, with a sharper focus on conceptual understanding and the connections between different areas of mathematics.
该大纲旨在培养超越常规程序的数学思维。考生需构建严谨的证明，对现实情境进行建模，并清晰地表达数学推理。新的变化进一步强化了这些原则，更加注重概念理解以及数学不同领域之间的联系。
For 2026, Cambridge has restructured some topics to improve progression from the Pre-U Mathematics course and to align more closely with the demands of undergraduate study. Notably, some content previously only examined in Paper 2 is now distributed across both pure papers, while the applied papers have been enriched with contemporary applications.
在2026年，剑桥重组了部分主题，以改善从Pre-U数学课程的进阶，并更贴近本科学习的要求。值得注意的是，一些以前只在试卷二中考查的内容现在分布到两份纯数试卷中，而应用试卷则加入了更多当代应用。
2. Revised Syllabus Content for 2026 | 2026年修订的教学大纲内容
The most visible change is the introduction of additional content across all four papers while retiring a few legacy topics. The table below summarises the key additions and removals.
最明显的变化是所有四份试卷都新增了内容，同时删去了一些遗留主题。下表总结了关键的增加与删减。
| Paper | New topics for 2026 | Removed topics |
|---|---|---|
| Pure 1 | Hyperbolic functions and their inverses; matrix diagonalisation; systematic curve sketching with asymptotes | Simple rational function inequalities (moved to Pre‑U Mathematics) |
| Pure 2 | Second‑order linear differential equations with constant coefficients and simple forcing terms; polar coordinates area and arc length; proof by induction for divisibility and inequalities | Some complex number loci (integrated into Pure 1) |
| Statistics | Geometric and negative binomial distributions; chi‑squared goodness‑of‑fit test; confidence intervals for the mean of a normal distribution with unknown variance using the t‑distribution | Permutation and combination identities (now assumed knowledge) |
| Mechanics | Centres of mass of composite bodies and variable density rods; work done by a variable force; introduction to rigid body rotation and moment of inertia for simple shapes | Relative motion in one‑dimension only (now part of Pre‑U Mathematics) |
It is essential to study the official syllabus document for the full list of subtopics, but the table gives a clear picture of the shifting emphasis: more calculus‑heavy applications, greater attention to mathematical structure (diagonalisation, proof by induction) and a modernised statistics component that prepares students for data‑driven degrees.
务必查阅官方大纲文件获取完整子主题清单，但上表清晰地展示了重点的转移：更多微积分密集型的应用、更强调数学结构（对角化、归纳法证明）以及经现代化改造的统计部分，为学生进入数据驱动的学位课程做好准备。
3. Changes in Pure Mathematics Papers | 纯数试卷的变化
icitly incorporates hyperbolic functions, previously an advanced extension topic. Candidates must be able to differentiate and integrate hyperbolic functions, prove identities such as cosh²x – ving inverse hyperbolics. A typical question might ask them to express sinh(ln 2) exactly.
试卷一（纯数1）现在明确纳入双曲函数，这以前属于高级拓展主题。考生必须能够对双曲函数进行微分和积分，证明如 cosh²x – sinh²x = 1 这样的恒等式，并求解涉及反双曲函数的方程。典型题目可能要求他们精确求出 sinh(ln 2) 的值。
genvalues for 2×2 and symmetric 3×3 matrices, and to use diagonalisation for simplifying powers of matrices. The key equation to diagonalise a matrix M is
矩阵代数已拓展至包含对角化及其几何意义。考生需要为 2×2 矩阵和对称 3×3 矩阵求特征向量与特征值，并利用对角化简化矩阵的幂。将矩阵 M 对角化的关键方程是
M = PDP⁻¹
where P is the matrix of eigenvectors and D is the diagonal matrix of eigenvalues. This change raises the overall algebraic demand of Paper 1.
其中 P 为特征向量矩阵，D 为特征值对角矩阵。这一变化提高了试卷一整体的代数要求。
Paper 2 (Pure Mathematics 2) now features second‑order linear ordinary differential equations with constant coefficients in the form
试卷二（纯数2）现在包含常系数二阶线性常微分方程，其形式为
a d²y/dx² + b dy/dx + c y = f(x)
terpreting solutions in contexts such as damped oscillations. Proof by induction has been strengthened: candidates may be asked to prove divisibility statements like '6ⁿ – 1 is divisible by 5 for all positive integers n' s are now explored more deeply, including area enclosed by a polar curve r = f(θ) given by
其中 f(x) 可以是多项式、指数函数或三角函数。学生需求出余函数和特解，并在阻尼振荡等情境中解释解的意义。归纳法证明得到强化：考生可能需证明整除性命题，如“对所有正整数 n, 6ⁿ – 1 能被 5 整除”，或使用归纳法证明不等式。极坐标也得到更深入的探讨，包括由极坐标曲线 r = f(θ) 所围成的面积
A = ½ ∫ r² dθ
and the arc length formula. These additions bring Paper 2 closer to first‑year university pure mathematics.
以及弧长公式。这些新增内容使试卷二更接近大学一年级的纯数课程。
4. Statistics and Probability Enhancements | 统计学与概率的加强
oduction of the geometric distribution Geo(p) with probability mass function P(X = k) = (1 – p)k–1 p and the negative binomial distribution reflects the growing importance of waiting‑time problems in actuarial science and machine learning. Candidates will be asked to calculate expectations, variances and to distinguish between these distributions and the binomial.
统计试卷经历了显著的现代化改造。引入几何分布 Geo(p)，其概率质量函数为 P(X = k) = (1 – p)k–1 p，以及负二项分布，反映了等待时间问题在精算科学和机器学习中日益增长的重要性。考生将需要计算期望、方差，并区分这些分布与二项分布。
The chi‑squared (χ²) goodness‑of‑fit test is a major new hypothesis test. Students must calculate the test statistic
卡方 (χ²) 拟合优度检验是一项重要的新假设检验。学生必须计算检验统计量
χ² = Σ (O – E)² / E
where O and E are observed and expected frequencies, and compare it against the appropriate critical value. This extends their understanding of hypothesis testing beyond the familiar normal and t‑tests, and links to the concept of degrees of freedom.
其中 O 与 E 分别为观测频数和期望频数，并将其与适当的临界值比较。这将他们对假设检验的理解扩展到熟悉的正态检验和 t 检验之外，并与自由度的概念相关联。
Confidence intervals now explicitly include intervals for the mean of a normal distribution when the population variance is unknown, requiring the use of the t‑distribution. Together, these changes encourage a more investigative approach to data analysis, with greater emphasis on interpreting results in real‑world contexts, such as medical trials and quality control.
置信区间现在明确包含总体方差未知时正态分布均值的置信区间，这需要使用 t 分布。这些变化共同鼓励了对数据分析采取更具探究性的方法，更强调在医学试验和质量控制等现实情境中解释结果。
5. Mechanics and Modelling Updates | 力学与建模更新
The Mechanics paper now covers centres of mass for composite bodies and rods with variable density. For a non‑uniform rod of length L with linear density ρ(x), the centre of mass is given by
力学试卷现在涵盖组合物体和变密度杆的质心。对于长度为 L、线密度为 ρ(x) 的非均匀杆，质心由下式给出
x̄ = (∫₀ᴸ x ρ(x) dx) / (∫₀ᴸ ρ(x) dx)
This requires confident integration skills and the ability to set up meaningful physical models.
这需要熟练的积分技巧和建立有意义物理模型的能力。
Work done by a variable force is another calculus‑ along a path. Combined with the principle of conservation of energy, this deepens the link between mechanics and pure mathematics.
变力做功是另一项微积分密集型的新增内容。取代仅有的恒力，考生需要沿路径计算形式为 ∫ F(x) dx 的积分。结合能量守恒原理，这加深了力学与纯数学之间的联系。
Rigid body rotation makes a first appearance in the Pre‑U course. Students are introduced to the moment of inertia for simple shapes such as a uniform rod or a disc about an axis of symmetry, and apply the rotational analogue of Newton's second law:
刚体转动在Pre‑U课程中首次出现。学生将学习简单形状（如均匀杆或圆盘绕对称轴）的转动惯量，并应用牛顿第二定律的转动类比：
τ = I α
where τ is the net torque, I the moment of inertia and α the angular acceleration. While the treatment remains elementary, it provides a valuable foundation for engineering and physics undergraduates.
其中 τ 为净力矩，I 为转动惯量，α 为角加速度。尽管处理方式仍是入门级的，但它为工程和物理专业的本科生提供了宝贵的基础。
6. Assessment Objectives and Weightings | 评估目标与权重调整
From 2026, the weighting of assessment objectives (AOs) has been rebalanced to reflect the greater emphasis on higher‑order thinking. The table below compares the old and new weightings for the overall qualification.
从2026年起，评估目标 (AO) 的权重被重新平衡，以反映对高阶思维的更大重视。下表比较了整体资格新旧权重的对比。
| Assessment Objective | Pre‑2026 weighting | 2026 weighting |
|---|---|---|
| AO1: Knowledge and use of mathematical techniques | 50% | 40% |
| AO2: Reason, interpret and communicate mathematically | 30% | 35% |
| AO3: Solve problems in mathematics and other contexts | 20% | 25% |
The reduction in AO1 does not mean less mathematical content; rather, more marks are now allocated to questions that require explanation, interpretation, evaluation and the construction of chains of reasoning. For instance, a typical AO2 question might ask candidates to 'explain why a given sequence converges' or to 'interpret the meaning of a confidence interval in context'.
AO1 的减少并不意味着数学内容变少；相反，现在有更多分数分配给需要解释、解读、评价和构建推理链的题目。例如，一道典型的 AO2 题可能会要求考生“解释为何给定数列收敛”或“在上下文中解释置信区间的含义”。
AO3 questions often present unfamiliar scenarios, such as modelling the decay of a chemical concentration using differential equations and then critiquing the model's assumptions. This shift rewards depth of understanding over rote application, aligning with university expectations.
AO3 题通常呈现不熟悉的情境，例如用微分方程对化学浓度衰减进行建模，然后评论模型的假设。这一转变奖励理解的深度而非机械应用，与大学的期望一致。
7. Calculator and Technology Policy | 计算器与技术政策
Cambridge has updated its calculator policy for the 2026 Pre‑U Further Mathematics examinations. The use of a graphic display calculator (GDC) with statistical and matrix functions is now strongly recommended, though not mandatory. Casio fx‑CG50 and TI‑Nspire CX (non‑CAS) are common approved models.
剑桥已更新2026年Pre‑U进阶数学考试的计算器政策。现在强烈建议使用具有统计和矩阵功能的图形显示计算器 (GDC)，但并非强制。Casio fx‑CG50 和 TI‑Nspire CX（非CAS版）是常见的获准型号。
Candidates are not permitted to use calculators or software with computer algebra system (CAS) capabilities during examinations. This means symbolic differentiation, integration and algebraic manipulation must be performed by hand. However, GDCs can be used to check numerical answers, perform matrix multiplication, find eigenvalues and compute statistical summaries quickly.
考生不得在考试中使用具有计算机代数系统 (CAS) 功能的计算器或软件。这意味着符号微分、积分和代数运算必须手工完成。然而，图形计算器可用于检验数值答案、执行矩阵乘法、求特征值以及快速计算统计摘要。
It is vital to become fluent with the approved GDC well before the exam. The new style of questions may require interpreting graphs produced by the calculator or comparing numerical methods. Teachers are advised to integrate GDC skills into regular lessons, especially for statistical hypothesis testing and solving equations numerically.
在考试前熟练使用获准的图形计算器至关重要。新题型可能要求解读计算器生成的图形或比较数值方法。建议教师将图形计算器技能融入日常教学，尤其是在统计假设检验和数值求解方程方面。
8. Exam Format and Question Style | 考试形式与题型风格
The structure of the four papers remains largely unchanged in terms of timing and marks: each paper is 2 hours and carries 75 marks. However, the internal balance of question types has shifted. Each paper now includes a dedicated 'modelling and reasoning' section worth approximately 20 marks, where candidates are presented with an extended problem that combines several topics.
四份试卷在时间和分值上的结构基本保持不变：每份试卷时长2小时，满分75分。然而，题目类型的内部平衡已经改变。每份试卷现在包含一个专门的“建模与推理”部分，分值约20分，向考生呈现一个结合了多个主题的拓展问题。
Command words have been refined for greater clarity: 'Determine', 'Prove', 'Show that', 'Evaluate', 'Interpret' and 'Criticise' appear more frequently. 'Evaluate
