一、0607国际数学与0580普通数学的区别 | 0607 International Mathematics vs 0580 Mathematics
剑桥IGCSE数学体系下共有三个常见课程：0580普通数学、0606附加数学与0607国际数学。0607国际数学专为计划继续学习IB数学或A-Level数学的学生设计，其最鲜明的特点是全程要求使用图形计算器。与0580相比，0607的题目更强调探究性、逻辑推理与多知识点的综合运用，代数与函数所占权重更高，并且纳入了基础微积分内容。选课前请务必确认学校开设的是哪一个课程，并判断它是否与你未来的大学预科方向相匹配。
Cambridge IGCSE offers three common mathematics courses: 0580 Mathematics, 0606 Additional Mathematics and 0607 International Mathematics. The 0607 course is designed for students planning to continue with IB or A-Level mathematics, and its most distinctive feature is the requirement to use a graphical calculator throughout. Compared with 0580, questions in 0607 place greater emphasis on investigation, logical reasoning and the integration of multiple topics. Algebra and functions carry a higher weighting, and introductory calculus is included. Before choosing, confirm which course your school offers and whether it matches your future pre-university direction.
二、0607的考试结构与分级 | Exam Structure and Core and Extended Tiers
0607考试分为核心与拓展两个层级。核心层级对应成绩C至G，拓展层级对应A*至E。以拓展层级为例，共设三份试卷：Paper 1为不含计算器的笔试，Paper 2允许使用图形计算器，Paper 3则是一份独立的探究性试卷，重点考查数学建模与问题解决能力。核心层级同样设有三份试卷，难度与内容范围相应降低。弄清楚每份试卷的题型构成、分值与考试时长，是制定复习计划的第一步，也能帮助你在考试当天合理分配时间。
The 0607 examination is divided into Core and Extended tiers. Core leads to grades C to G, while Extended leads to grades A* to E. Taking the Extended tier as an example, there are three papers: Paper 1 is a written paper without a calculator, Paper 2 allows the graphical calculator, and Paper 3 is a separate investigation paper focusing on mathematical modelling and problem solving. The Core tier also has three papers, with reduced difficulty and content range. Understanding the question types, mark allocation and duration of each paper is the first step in planning your revision, and it helps you allocate time sensibly on exam day.
三、图形计算器的核心作用 | The Role of the Graphical Calculator
图形计算器是0607区别于其他IGCSE数学课程的关键所在。它不仅要完成普通数值运算，还被要求执行函数图像绘制、方程求根、统计图表制作与概率分布计算等任务。考生需要熟悉自己机型的高频按键路径，例如如何求两个函数图像的交点、如何拟合回归直线、如何计算正态分布曲线下的面积。考前务必确认你的计算器型号在剑桥允许清单之内，并在限时条件下反复演练这些操作，把计算器变成提分的工具而非拖累。
The graphical calculator is what sets 0607 apart from other IGCSE mathematics courses. It must handle not only ordinary arithmetic but also tasks such as plotting function graphs, finding roots of equations, producing statistical diagrams and calculating probability distributions. Candidates must be familiar with the high-frequency key sequences on their own model, for example finding intersections of two graphs, fitting a regression line, or calculating the area under a normal distribution curve. Before the exam, confirm that your calculator model is on the permitted list from Cambridge, and rehearse these operations repeatedly under timed conditions so the calculator becomes an asset rather than a burden.
四、如何选择核心还是拓展层级 | Choosing Between Core and Extended
选择核心还是拓展层级，主要取决于你的数学基础与升学目标。如果你的目标是申请竞争激烈的大学预科课程，拓展层级提供的A*至E成绩范围更有利。拓展层级的考试范围包含全部核心内容并额外增加微积分等高级主题，对图形计算器的依赖也更高。如果你对数学信心不足或时间有限，可以先以核心层级为目标，确保基础扎实，再视情况向拓展过渡。与老师和家长充分沟通后再做决定，避免中途频繁更换层级。
Choosing between the Core and Extended tiers depends mainly on your mathematical foundation and progression goals. If you are aiming for competitive pre-university courses, the Extended tier, with its A* to E grade range, is more advantageous. The Extended syllabus covers all Core content and adds advanced topics such as calculus, with a heavier reliance on the graphical calculator. If you lack confidence or have limited time, you can first target the Core tier to secure a solid foundation, then move up to Extended as circumstances allow. Discuss thoroughly with your teacher and parents before deciding, and avoid switching tiers frequently mid-course.
五、代数与函数的重点内容 | Algebra and Functions: Core Content
代数与函数在0607中占分最重，也是多数考生的主攻方向。重点内容包括二次函数的配方与图像变换、复合函数与反函数、指数与对数、以及方程与不等式的求解。图形计算器可以帮助验证答案，但评分标准对步骤分的要求很高，必须写出完整的代数过程。建议把配方法、换元法和因式分解练到熟练的程度，因为它们是解大多数题目的基础工具。掌握了扎实的代数功底，后面的几何、微积分部分都会轻松许多。
Algebra and functions carry the largest share of marks in 0607 and are the main focus for most candidates. Key topics include completing the square for quadratics and graph transformations, composite and inverse functions, exponentials and logarithms, and solving equations and inequalities. The graphical calculator can help verify answers, but the mark scheme demands strong method marks, so you must write out the full algebraic process. Practise completing the square, substitution and factorisation until they are fluent, because these are the foundational tools for most questions. With solid algebraic skills, the later geometry and calculus sections become much easier.
六、几何、三角与测量 | Geometry, Trigonometry and Mensuration
几何与三角部分要求掌握圆的性质、相似三角形、正弦定理与余弦定理，以及三角函数图像的变换。测量部分涉及二维与三维图形的面积、体积和表面积公式。0607的几何题常常与代数相结合，例如用三角函数解方程、用坐标几何求两点间距离，或用向量描述位置关系。解题时先画出清晰的示意图，标出已知与未知量，再选择最合适的公式，这样既能减少计算错误，也便于拿到步骤分。
The geometry and trigonometry section covers circle properties, similar triangles, the sine and cosine rules, and transformations of trigonometric graphs. Mensuration involves area, volume and surface area formulas for two-dimensional and three-dimensional shapes. Geometry questions in 0607 are often combined with algebra, for example using trigonometry to solve an equation, using coordinate geometry to find a distance, or using vectors to describe position. Draw a clear diagram first, label the known and unknown quantities, then choose the most suitable formula. This reduces calculation errors and helps you earn method marks.
七、统计与概率的题型特点 | Statistics and Probability Question Types
统计部分包括数据表示、集中趋势与离散程度的度量、累积频率图和箱线图。概率部分涵盖树状图、条件概率与独立事件。0607特别鼓励用图形计算器处理数据，例如生成直方图、散点图或计算相关系数。要特别注意区分中位数与平均数、众数与模态、互斥事件与独立事件这些容易混淆的概念，考试常常在这里设置陷阱。做概率题时先明确事件之间的关系，再决定用加法还是乘法法则。
The statistics section includes data representation, measures of central tendency and spread, cumulative frequency graphs and box plots. Probability covers tree diagrams, conditional probability and independent events. 0607 particularly encourages using the graphical calculator to handle data, such as generating histograms, scatter diagrams or calculating correlation coefficients. Take special care to distinguish easily confused concepts like median versus mean, mode versus modal class, and mutually exclusive versus independent events, where examiners often set traps. For probability questions, first clarify the relationship between events, then decide whether to use the addition or multiplication rule.
八、微积分入门内容 | Introduction to Calculus
0607拓展层级包含基础微积分，这是它领先于0580的一大亮点。考生需要掌握多项式函数的求导、切线斜率的意义，以及利用导数判断函数的增减区间与驻点。积分部分以简单幂函数为主，重点理解积分与面积之间的关系。这部分内容为后续A-Level数学打下直接基础。建议用函数图像直观理解导数是切线的斜率、积分是曲线下的面积这两个核心含义，而不是死记公式，这样遇到陌生题型也能灵活应对。
The 0607 Extended tier includes introductory calculus, a key advantage over 0580. Candidates must master differentiating polynomial functions, the meaning of the gradient of a tangent, and using derivatives to identify increasing and decreasing intervals and stationary points. Integration focuses mainly on simple power functions, with emphasis on the relationship between integration and area. This content provides direct preparation for A-Level mathematics. Use function graphs to understand intuitively that a derivative is the gradient of a tangent and an integral is the area under a curve, rather than memorising formulas by rote, so you can respond flexibly to unfamiliar questions.
九、高效备考的三个阶段 | Three Stages of Effective Revision
高效备考可以分成三个阶段。第一阶段用四到六周系统梳理所有知识点，整理公式清单，建立专属错题本。第二阶段用四到六周集中刷历年真题，严格限时完成，并对照评分标准逐题打分，记录每题失分原因。第三阶段用最后两周查漏补缺，重点攻克薄弱题型和图形计算器操作。每个阶段结束时都要做一次完整的模拟测试，用分数检验复习进度，并据此调整下一阶段的计划。
Effective revision can be divided into three stages. In stage one, spend four to six weeks systematically reviewing all topics, compiling a formula list and building a personal error log. In stage two, spend four to six weeks working through past papers under strict time limits, marking each question against the mark scheme and recording why marks were lost. In stage three, use the final two weeks to close gaps, focusing on weak question types and graphical calculator operations. End each stage with a full mock test, use the score to check your progress, and adjust the next stage's plan accordingly.
十、常见失分点与应对策略 | Common Mistakes and How to Avoid Them
常见失分点集中在几个方面：忘记写单位或写错单位、代数步骤跳步导致方法分丢失、图形计算器操作不熟练而浪费时间、审题不清答非所问，以及计算完成后不检查答案的合理性。应对策略是养成写完整步骤的习惯，每道题都标注单位，考前专门演练计算器的高频操作，审题时用笔划出关键词，答完后花几秒检查概率是否在0到1之间、长度是否为正数。这些细节往往决定了成绩能否跨越一个等级。
Common mistakes cluster in a few areas: forgetting units or using the wrong units, skipping algebraic steps and losing method marks, wasting time through unfamiliar calculator operations, misreading the question, and failing to check whether an answer is reasonable. The remedies are to build the habit of showing full working, annotate units on every answer, rehearse high-frequency calculator operations before the exam, underline keywords when reading questions, and after each question check that a probability lies between 0 and 1 or a length is positive. These details often determine whether a grade crosses to the next level.
十一、考试当天的实用建议 | Practical Advice for Exam Day
考试当天提前到场，检查图形计算器的电量、备用电池和必要的文具。答题时先通读全卷，从最有把握的题目开始，为较难的探究题预留充足时间。如果计算器出现故障，保持冷静，改用代数方法也能完成大部分步骤，切勿因此自乱阵脚。每一题完成后花几秒检查答案是否合理。Paper 3探究题尤其要展示清晰的思路和完整的建模过程，让阅卷老师看到你的推理链条。
On exam day, arrive early and check the battery of your graphical calculator, spare batteries and necessary stationery. Read through the whole paper first, start with the questions you are most confident about, and reserve enough time for the harder investigation questions. If your calculator fails, stay calm; most steps can still be completed algebraically, so do not panic. After each question, spend a few seconds checking that the answer is reasonable. For the Paper 3 investigation, show clear reasoning and a complete modelling process so the examiner can see your chain of logic.
