| 次年1月 January | 补考场次 Second sitting |
3. Exam Format Overview | 考试形式概览
ESAT is a fully computer-based, multiple-choice examination. Each question offers five answer options, and candidates select the single correct answer. The entire test consists of two mandatory modules and additional subject-specific modules, totalling 99 questions across a 150-minute testing session.
ESAT 完全采用机考形式，全部为选择题。每道题提供五个选项，考生需选出唯一正确答案。整场考试由两个必考模块和若干学科模块组成，共 99 道题，总时长 150 分钟。
The distribution of time is structured so that each module is allocated exactly 40 minutes. Since the number of questions per module is fixed, candidates face an average of approximately 74 seconds per question, which places significant emphasis on both speed and accuracy.
考试时间分配方式为每个模块各 40 分钟。由于每模块题目数量固定，考生每道题平均仅有约 74 秒，这对答题速度和准确性都提出了很高要求。
4. Module Structure and Selection | 模块结构与选考规则
All candidates are required to sit Module 1 (Mathematics 1). In addition, candidates must choose two additional modules from the available options. The choice of optional modules depends on the specific Cambridge course the candidate is applying for.
所有考生必须完成模块 1（数学 1）。此外，考生还需从可选模块中任选两个模块。可选模块的选择取决于考生所申请的剑桥具体专业方向。
Available optional modules are: Module 2 (Physics), Module 3 (Chemistry), Module 4 (Biology), and Module 5 (Mathematics 2). A candidate applying for Engineering would typically select Physics and Mathematics 2, whereas a Natural Sciences applicant might choose Chemistry and Biology, depending on their intended specialisation.
可选模块包括：模块 2（物理）、模块 3（化学）、模块 4（生物）和模块 5（数学 2）。申请工程学的考生通常选择物理和数学 2，而自然科学申请者则可能根据未来的专业方向选择化学和生物。
| 模块 Module | 内容 Content | 题量 Questions | 时长 Time |
| 模块1 Module 1 | 数学1 Mathematics 1 | 27 | 40分钟 40 mins |
| 模块2 Module 2 | 物理 Physics | 27 | 40分钟 40 mins |
| 模块3 Module 3 | 化学 Chemistry | 27 | 40分钟 40 mins |
| 模块4 Module 4 | 生物 Biology | 27 | 40分钟 40 mins |
| 模块5 Module 5 | 数学2 Mathematics 2 | 27 | 40分钟 40 mins |
5. Total Question Count and Timing | 总题量与总时长
The complete ESAT comprises three modules per candidate: the mandatory Mathematics 1 module plus two elective modules. Each module contains exactly 27 questions, resulting in a total of 81 questions per candidate rather than 99 as sometimes mistakenly reported.
完整 ESAT 考试包括三个模块：必考的数学 1 加上两个自选模块。每个模块恰好包含 27 道题，因此每位考生总共需作答 81 题，而非有些资料中误报的 99 题。
Each of the three modules is independently timed at 40 minutes, giving a total testing time of 120 minutes. Between modules, candidates may have a brief transition screen to move to the next section, though actual intermission time is minimal and not counted as break time.
三个模块各自独立计时 40 分钟，总考试时长为 120 分钟。模块之间会有简短的过渡界面供考生切换到下一部分，但此过渡时间极短，不计入休息时间。
总题数 = 3 个模块 × 27 题 = 81 题
Total Questions = 3 modules × 27 = 81
总时长 = 3 个模块 × 40 分钟 = 120 分钟
Total Time = 3 modules × 40 min = 120 min
6. Scoring Mechanism | 评分机制
ESAT follows a straightforward scoring rule: each correctly answered question earns one raw mark. There is no negative marking or penalty for incorrect answers, and no marks are deducted for unanswered questions.
ESAT 遵循简洁明了的计分规则：每答对一题得 1 分原始分。答错不扣分，不设负分惩罚，未作答的题目同样不扣分。
This absence of negative marking is a crucial strategic consideration. Even when a candidate is uncertain of the correct answer, there is no disadvantage to making an educated guess. Random guessing, however, has an expected value of 0.2 marks per question since each question offers five options.
不设倒扣分的规则是重要的策略考量因素。即使考生不确定正确答案，进行合理猜测也不会带来任何损失。不过，纯随机猜测的期望值为每题 0.2 分，因为每道题有五个选项。
最终原始分 = 答对题数
Raw Score = Number of Correct Answers
满分 = 81 分
Maximum Raw Score = 81
7. Conversion to ESAT Scaled Score | 等级分换算
The raw score from each module is converted into a scaled score ranging from 1.0 to 9.0, where 1.0 represents the lowest achievable level and 9.0 the highest. This conversion is performed separately for each module using a statistical procedure that considers the difficulty of the specific test version administered.
每个模块的原始分会被转换为 1.0 至 9.0 之间的等级分，其中 1.0 代表最低水平，9.0 代表最高水平。每个模块独立进行换算，采用统计方法并综合该次考试版本的具体难度来校准。
The scaled scores are reported to one decimal place, such as 6.5 or 7.8. Cambridge admissions tutors receive these scaled scores alongside information about the candidate’s overall performance band, which summarises relative performance across all test-takers.
等级分保留一位小数，例如 6.5 或 7.8。剑桥招生导师会收到这些等级分，以及考生整体表现等级的相关信息，用于综合衡量所有考生的相对表现。
It is important to understand that the conversion from raw to scaled score is not a simple percentage-based linear mapping. The scaling procedure is designed to ensure fairness across different test sittings and question paper versions, accounting for minor variations in difficulty.
需要明确的是，从原始分到等级分的转换并非简单的百分比线性映射。该换算机制旨在确保不同考试场次和不同试卷版本之间的公平性，以消除题目难度的微小差异。
8. Interpretation of Scores | 成绩解读与录取参考
There is no official “pass” or “fail” threshold for ESAT, and the University of Cambridge does not publish a formal cut-off score. The test results are used in conjunction with other application components, including predicted A-Level grades, GCSE performance, personal statement, teacher references, and contextual data.
ESAT 没有官方的及格或不及格分数线，剑桥大学也不公布正式的截止分数。考试成绩将与申请其他组成部分综合考量，包括 A-Level 预估成绩、GCSE 表现、个人陈述、教师推荐信和背景数据等。
Historically, for the predecessor tests (NSAA and ENGAA), successful Cambridge applicants typically achieved scores well above the median, often in the range of 6.5 or higher on their strongest modules. However, these figures are indicative rather than definitive, as scoring patterns vary annually.
从历史数据来看，在前身考试（NSAA 和 ENGAA）中，获得剑桥录取的申请者通常成绩远高于中位数，强项模块多在 6.5 分以上。然而这些数据仅供参考而非确定性标准，因为每年分数分布会有所变化。
ESAT scores play a significant role in the shortlisting interview process. Applicants who score below a certain threshold may not be invited to interview, while higher scores improve the likelihood of receiving an interview invitation, particularly for oversubscribed courses.
ESAT 成绩在面试选拔环节中发挥着重要作用。分数低于一定门槛的申请者可能无法获得面试邀请，而较高的分数则能增加收到面试邀约的可能性，尤其是对申请人数远超名额的专业而言。
9. Score Reporting to Candidates | 成绩报告方式
Candidates receive their ESAT results approximately five to six weeks after each test sitting. Cambridge applicants’ scores are automatically shared with the University of Cambridge admissions team. Non-Cambridge institutions do not receive ESAT scores since the test is exclusive to Cambridge.
考生在每场考试结束后约五至六周收到 ESAT 成绩。剑桥申请者的成绩会自动发送给剑桥大学招生团队。由于 ESAT 是剑桥专属考试，其他院校不会收到考生成绩。
The result statement provided to candidates includes individual scaled scores for each of the three modules taken, as well as the overall average scaled score. No detailed answer key or per-question breakdown is released to candidates.
考生收到的成绩单包含三个模块各自的等级分以及总体平均等级分。考试机构不会向考生公布详细答案或逐题得分明细。
Candidates who sat the October test and subsequently receive an interview invitation will have their scores discussed during the interview process. It is therefore advisable for applicants to understand their own performance and be prepared to reflect on their results.
参加 10 月份考试并随后收到面试邀请的考生，其成绩将在面试过程中被讨论。因此建议申请者充分了解自身表现，并准备好对自己的成绩进行反思和回应。
10. Preparation Strategies for ESAT | ESAT 备考策略
Given the tight time pressure of approximately 74 seconds per question, fluency in core mathematical and scientific concepts is paramount. Candidates should practise working accurately under timed conditions, using past NSAA and ENGAA papers as well as official ESAT sample questions released by Cambridge Assessment Admissions Testing.
考虑到每道题仅约 74 秒的紧张时间压力，对核心数学和科学概念的熟练掌握至关重要。考生应在限时条件下练习准确作答，使用 NSAA 和 ENGAA 历年真题以及剑桥官方发布的 ESAT 样题进行训练。
Since there is no negative marking, priority should be given to completing all questions rather than spending excessive time on any single item. A well-calibrated time management strategy typically involves flagging uncertain questions and returning to them after completing the guaranteed marks in each module.
由于考试不设倒扣分，应优先完成所有题目，而非在某一题上过度耗时。合理的时间管理策略通常是将不确定的题目标记出来，在完成该模块中较有把握的题目后再回头处理。
-
Master A-Level core content thoroughly before attempting past papers. | 在尝试真题前，先扎实掌握 A-Level 核心内容。
-
Practise mental arithmetic and avoid reliance on calculators, as ESAT does not permit calculator use. | 练习心算能力，避免依赖计算器，因为 ESAT 不允许使用计算器。
-
Simulate exam conditions by completing full 120-minute mock tests with strict timing. | 通过完成严格限时的 120 分钟全套模拟测试来模拟真实考试环境。
-
Review each incorrect answer to identify recurring patterns in reasoning errors. | 逐题复盘错题，找出推理错误中的共性规律。

Familiarise yourself with the Pearson VUE computer interface through the free demo test available online. | 通过培生 VUE 官网提供的免费演示测试，熟悉机考界面操作。
11. ESAT vs. Old NSAA and ENGAA | ESAT 与前身考试对比
The most significant structural change from the old NSAA and ENGAA is the streamlined modular system. ENGAA had one mathematics section and one physics section with a combined paper format, while NSAA offered different section combinations depending on course. ESAT unifies the format across all courses with a consistent first mathematics module.
与前身 NSAA 和 ENGAA 相比，最显著的结构性变化是精简的模块化系统。ENGAA 原先为数学和物理两大部分组成的综合卷，NSAA 则根据不同专业提供不同的组合方式。ESAT 则统一了所有专业的考试格式，固定以数学 1 作为首个模块。
Another major difference is the administration platform. Both predecessor tests were paper-based, whereas ESAT is fully digitalised. This transition to computer-based testing reduces administrative overhead and enables more efficient score processing and standardisation.
另一项重大差异在于考试实施平台。前身考试均为纸质形式，而 ESAT 已全面数字化。向机考模式的过渡降低了考务管理成本，也使得成绩处理和标准化更加高效。
The scoring scale has also been refined. While NSAA and ENGAA reported scores to one decimal place within the 1.0-9.0 range, ESAT maintains this scale but the conversion methodology has been recalibrated to account for the new test structure, ensuring comparability across different module combinations.
评分量表也经过了优化。NSAA 和 ENGAA 同样采用 1.0-9.0 范围并保留一位小数的报告方式，ESAT 沿用这一量表，但换算方法已根据新的考试结构加以重新校准，以确保不同模块组合之间的可比性。
12. Important Dates and Final Advice | 重要日期与备考建议
For the 2025 admission cycle, the ESAT registration deadline is 16 September 2025, and the main test date is 15-16 October 2025. The supplementary sitting for eligible candidates is scheduled for January 2026. Candidates should verify exact dates on the official Cambridge Admissions website as these may adjust annually.
就 2025 年入学周期而言，ESAT 报名截止日期为 2025 年 9 月 16 日，主要考试日期为 2025 年 10 月 15-16 日。符合条件考生的补考场次安排在 2026 年 1 月。考生应通过剑桥招生官网核实具体日期，因为这些日期可能每年有所调整。
Beyond technical preparation, mental readiness is equally important. Candidates should arrive at the test centre well-rested, bring the required identification documents, and arrive at least 30 minutes before the scheduled start time. Understanding the computer-based interface in advance eliminates unnecessary stress on test day.
除技术层面的备考外，心理准备同样重要。考生应在考试前保证充足休息，携带所需身份证明文件，并至少在开考前 30 分钟到达考点。提前熟悉机考界面可有效减少考试当天的无谓紧张。
Ultimately, ESAT serves as one component of a holistic assessment. A well-prepared candidate with genuine subject proficiency, consistent performance across all modules, and sound time management will be optimally positioned regardless of scoring fluctuations from year to year. Consistent practice, structured revision, and a calm approach on test day are the key pillars of ESAT success.
归根结底，ESAT 只是全面评估中的一个组成部分。具备扎实学科功底、在各模块中表现稳定且擅长时间管理的充分备考者，无论年度评分如何波动，都将处于最有利的竞争位置。持续练习、系统复习以及考试当天的沉着应对，是 ESAT 取得成功的三大核心支柱。
