2. University of Cambridge Mathematics Offers | 剑桥大学数学专业录取要求
Cambridge is synonymous with mathematical excellence. The standard A-level offer for the Mathematical Tripos is A*A*A, with A* in Mathematics and Further Mathematics as an absolute requirement. In practice, most successful applicants exceed this. All candidates must take the Sixth Term Examination Paper (STEP), typically achieving grade 1 in both STEP 2 and STEP 3, though some colleges may require a grade 1 and a grade 2. The STEP condition is often the major hurdle, as the tests demand considerable mathematical maturity beyond the A-level syllabus.
剑桥是数学卓越的代名词。数学本科专业（Mathematical Tripos）的标准A-level录取要求是A*A*A，且必须在数学和进阶数学中取得A*。实际上，大多数成功的申请者成绩远超此要求。所有申请者必须参加第六学期考试（STEP），通常需要在STEP 2和STEP 3中都获得1等成绩，部分学院可能要求一个1等和一个2等。STEP条件往往是主要障碍，因为这些考试要求远超出A-level大纲的数学成熟度。
- Standard A-level offer: A*A*A with A* in both Mathematics and Further Mathematics
- 标准A-level录取：A*A*A，数学和进阶数学均为A*
- Required admission test: STEP 2 and STEP 3 (typically grade 1, 1)
- 必要入学考试：STEP 2和STEP 3（通常需成绩1等、1等）
- Contextual offers may drop to A*AA, but STEP remains mandatory
- 特殊背景下录取可能降至A*AA，但STEP仍然是强制要求
3. University of Oxford Mathematics Offers | 牛津大学数学专业录取要求
Oxford’s mathematics courses (single honours or joint with Statistics, Philosophy, or Computer Science) demand A*A*A at A-level, featuring A* in Mathematics and Further Mathematics if both are taken. Unlike Cambridge, Oxford uses the Mathematics Admissions Test (MAT) as its pre-interview assessment. A strong MAT score is essential to secure an interview invitation. The test emphasises logical thinking, precision, and the ability to apply core concepts in unfamiliar contexts. Oxford also conducts rigorous academic interviews, making the overall process highly selective.
牛津大学的数学课程（纯数学或与统计学、哲学、计算机科学联合的专业）要求A-level成绩达到A*A*A，如果同时修读数学和进阶数学，两科都需A*。与剑桥不同，牛津采用数学入学测试（MAT）作为面试前的评估。优秀的MAT成绩是获得面试邀请的关键。该测试强调逻辑思维、精确性以及在不熟悉的情境中运用核心概念的能力。牛津还会进行严格的学术面试，整体选拔过程极为严苛。
- Offer: A*A*A with A* in Maths and Further Maths
- 录取条件：A*A*A，数学和进阶数学A*
- Test: MAT (no STEP requirement)
- 考试：MAT（无STEP要求）
- Typical successful MAT score: above 60 out of 100, with top candidates scoring 75+
- 典型的成功MAT分数：满分100，通常60分以上，顶尖申请者75分以上
4. Imperial College London Mathematics | 帝国理工学院数学专业
Imperial’s Department of Mathematics is one of the strongest in the world. Typical A-level offers are A*A*A, with A* in Mathematics and A* in Further Mathematics. For 2024 entry onwards, Imperial has shifted its entrance test requirement: applicants may need to take either the MAT or the Test of Mathematics for University Admission (TMUA), depending on the specific course. For straight Mathematics and Mathematics with Statistics, MAT is the primary test, while some joint honours programmes accept TMUA. The admissions team looks for high scores in these tests to differentiate among the many top-grade applicants.
帝国理工的数学系是世界上最强的之一。典型的A-level录取要求是A*A*A，数学和进阶数学均需A*。从2024年入学开始，帝国理工调整了入学考试要求：申请者可能需要参加MAT或大学入学数学测试（TMUA），具体取决于所选课程。纯数学和数学与统计专业主要要求MAT，而一些联合荣誉课程则接受TMUA。招生团队依靠这些考试的高分来区分众多高分申请者。
- Offer: A*A*A in Maths, Further Maths, and a third subject
- 录取：数学、进阶数学和第三门科目均A*A*A
- Test: MAT or TMUA (check course-specific requirements)
- 考试：MAT或TMUA（请查看具体课程要求）
- Context: strong STEP scores can also support an application, but are not formally required
- 说明：很好的STEP成绩也能为申请加分，但并非正式要求
5. LSE Mathematics-related Degrees | 伦敦政治经济学院数学相关专业
The London School of Economics does not offer single-honours mathematics, but its BSc Mathematics and Economics, BSc Mathematics with Economics, and BSc Financial Mathematics and Statistics are highly sought after. Typical A-level requirements are A*AA, with A* in Mathematics. Since 2022, LSE has required all applicants for these programmes to sit the TMUA. The test is used as a benchmark for mathematical reasoning, and a strong performance can significantly strengthen an application. LSE also values a well-argued personal statement and strong performance in A-level Further Mathematics, though the latter is not always compulsory.
伦敦政治经济学院不提供纯数学学位，但其数学与经济学、数学与经济、以及金融数学与统计学等本科课程备受追捧。典型的A-level要求是A*AA，其中数学须为A*。自2022年起，LSE要求这些课程的所有申请者参加TMUA考试。该测试被视为数学推理能力的基准，优异的表现能大大增强申请竞争力。LSE同样重视论证严谨的个人陈述，以及进阶数学的优异成绩，虽然后者并非总是必修。

6. University College London Mathematics | 伦敦大学学院数学专业
UCL’s mathematics degrees, including BSc Mathematics and MSci Mathematics, typically require A*A*A at A-level, with A* in both Mathematics and Further Mathematics. While UCL does not universally mandate an external entrance test, a high grade in STEP (either paper 2 or 3) or an A in AEA Mathematics can be part of a conditional offer for certain courses, especially for applicants who are not taking Further Mathematics to A2. The department views these qualifications as evidence of advanced problem-solving skills and often uses them as an alternative condition to standard A-level grades.
UCL的数学学位，包括BSc数学和MSci数学，通常要求A-level达到A*A*A，其中数学和进阶数学均需A*。尽管UCL并不普遍要求外部入学考试，但某些课程（尤其是没有修读A2进阶数学的申请者）的条件录取可能包含STEP（试卷2或3）的高分，或者AEA数学的A等成绩。数学系将这些资格视为高级问题解决能力的证明，并常将其作为标准A-level成绩的替代条件。
- Typical offer: A*A*A, with both Maths and Further Maths A*
- 典型录取：A*A*A，数学和进阶数学A*
- Alternative conditions: Grade 2 in STEP 2 or STEP 3, or an A in AEA Mathematics
- 替代条件：STEP 2或STEP 3中获得2等成绩，或AEA数学获得A
- No mandatory pre-interview test for most applicants
- 对大多数申请者，无强制性面试前测试
7. Understanding the STEP Exam | 解读STEP考试
STEP (Sixth Term Examination Paper) consists of two separate 3-hour papers: STEP 2 and STEP 3. Both are sat in June, and results are released in August, aligning with A-level results. Each paper contains 12 questions: 8 pure, 2 mechanics, and 2 probability/statistics. Candidates choose 6 questions to answer; each is marked out of 20. The final grade (S, 1, 2, 3, U) is based on a cumulative raw mark. STEP 2 is based on A-level Mathematics and Further Mathematics, while STEP 3 assumes full knowledge of Further Mathematics and introduces more advanced topics.
STEP（第六学期考试）由两场独立的3小时试卷组成：STEP 2和STEP 3。两者均在六月进行，成绩于八月发布，与A-level成绩同步。每张试卷包含12道题：8道纯数学、2道力学、2道概率与统计。考生选择6题作答，每题满分20分。最终等级（S、1、2、3、U）基于总分评定。STEP 2基于A-level数学和进阶数学内容，而STEP 3则预设完整的进阶数学知识，并引入更高级的主题。
| Paper | Duration | Questions | Typical Grade 1 boundary |
| STEP 2 | 3 hours | 12 (do 6) | ~75/120 (~63%) |
| STEP 3 | 3 hours | 12 (do 6) | ~69/120 (~58%) |
注册通常通过权威考试中心进行，截止日期在五月。必须提前查询具体日期。
8. Understanding the MAT | 解读MAT考试
The Mathematics Admissions Test (MAT) is a 2-hour 30-minute paper used by Oxford, and increasingly by Imperial and other universities. The test comprises 7 questions, of which candidates must answer 5 depending on their course of choice. Question 1 is 10 multiple-choice parts worth 40 marks; questions 2–7 are longer, each worth 15 marks. For Oxford Mathematics, applicants attempt questions 1, 2, 3, 4, and 5. The test is designed to be accessible with C1 and C2 knowledge from A-level, rewarding ingenuity rather than rote memorisation. Scores are out of 100.
数学入学测试（MAT）是一场时长2小时30分钟的考试，由牛津大学使用，帝国理工及其他大学也逐渐采用。试卷共7道题，考生根据所选课程回答其中5题。第1题为10道选择题，共40分；第2至7题为较长题目，每题15分。申请牛津数学的考生需回答第1、2、3、4、5题。考试基于A-level C1和C2的知识，奖励巧妙的思维而非死记硬背。满分为100分。
- Oxford average shortlisted score: typically 60–65; offer holders often score above 70
- 牛津入围平均分：通常60–65分；获得录取者往往高于70分
- Registration opens in September, test date late October/early November
- 报名从九月开始，考试日期在十月底或十一月初

9. STEP vs MAT: Which One to Take? | STEP与MAT：如何选择？
The choice between STEP and MAT is largely determined by your target universities. Cambridge demands STEP, no exceptions. Oxford demands MAT. Imperial and other universities may accept either test. If you are applying to both Cambridge and Oxford, you must prepare for both tests, but this is a heavy workload. In such cases, focus on the test required by your top choice and use the other as supplementary practice. The two exams test overlapping yet distinct skills: STEP rewards deep, multi-step algebraic manipulation and physical insight, while MAT emphasises speed, precision, and abstract reasoning.
STEP和MAT的选择主要取决于你的目标大学。剑桥一定要求STEP，牛津一定要求MAT。帝国理工等其他大学可能接受两种考试。如果你同时申请剑桥和牛津，则必须准备两种测试，但这负担很重。此时，应重点准备第一志愿所要求的考试，并将另一个作为补充练习。两种测试考察重叠但又不同的技能：STEP奖励深入的、多步骤的代数操作和物理直觉，而MAT则强调速度、精确度和抽象推理。
| Feature | STEP 2/3 | MAT |
| Duration | 3 hours each paper | 2 hours 30 minutes |
| Style | Extended structured/unstructured problems | MCQ + long questions |
| Calculator allowed | No | No |
| Syllabus | Full A-level Further Maths | C1/C2 level, but deeper |
10. Effective Preparation Strategies | 高效备考策略
The single most effective preparation method is working through past papers under timed conditions. For STEP, begin STEP 2 papers at least six months before the exam, slowly building up to STEP 3. Initially, do not worry about time; focus on understanding the structure of solutions. As you improve, strictly adhere to the 3-hour limit and practise selecting the six questions that play to your strengths. For MAT, consistent practice with the multiple-choice section is vital, as these 40 marks are the quickest to secure. Review university syllabi to identify gaps, particularly in proof, number theory, or mechanics, and fill them methodically.
最有效的备考方法是在计时条件下完成历年真题。备考STEP应至少提前六个月开始使用STEP 2试卷，逐渐过渡到STEP 3。初期不必担心时间，注重理解解题结构。随着能力提升，严格约束在3小时内完成，并练习选择最能发挥优势的六道题。对于MAT，持续练习选择题部分至关重要，因为这40分最容易稳稳拿下。对照大学大纲寻找知识盲点，尤其是证明、数论或力学部分，并系统性地加以弥补。
