1. The New Specifications at a Glance | 新教学大纲概览
The 2026 examinations will be based on new OCR Pre-U specifications for Biology (H020), Chemistry (H032), and Physics (H556). First teaching began in September 2024, allowing a full two-year programme before the terminal assessments in June 2026. Each specification has been reorganized to streamline content, update topics, and clarify progression from GCSE or IGCSE.
2026 年的考试将基于新的 OCR Pre-U 生物学（H020）、化学（H032）和物理学（H556）教学大纲。首次教学于 2024 年 9 月开始，在 2026 年 6 月的终点评估之前提供完整的两年课程。每个教学大纲都经过了重新组织，以精简内容、更新主题并明确从 GCSE 或 IGCSE 的衔接。
The new specifications are fully linear, with all externally assessed components taken at the end of the course. This structure encourages deep, sustained learning rather than modular cramming. While the core subject content remains rigorous, the update has reduced some outdated material and introduced contemporary applications such as CRISPR gene editing in Biology, green chemistry in Chemistry, and quantum technologies in Physics.
新教学大纲是完全线性的，所有外部评估的组成部分都在课程结束时进行。这种结构鼓励深入、持续的学习，而不是模块化的突击学习。虽然核心学科内容依然严格，但该更新减少了一些过时的材料，并引入了当代应用，如生物学中的 CRISPR 基因编辑、化学中的绿色化学和物理学中的量子技术。
2. Revised Assessment Structure | 修订后的评估结构
Each science subject now features a consistent three-component assessment model. All candidates take three written papers that cover the full specification. The components are typically titled ‘Foundations in Science’, ‘Scientific Literacy’, and ‘Practical Skills and Synoptic Assessment’. This replaces older models where some papers were optional or had different weightings.
每门科学科目现在都具有一致的三部分评估模型。所有考生都要参加涵盖整个教学大纲的三份笔试试卷。这些部分通常标题为“科学基础”、“科学素养”和“实践技能与综合评估”。这取代了以前部分试卷可选或权重不同的旧模式。
The timing, marks, and weightings have been recalibrated. For example, in the new Pre-U Biology, Paper 1 lasts 2 hours 15 minutes and contributes 35 % of the total marks, while Papers 2 and 3 each last 2 hours and contribute 32.5 %. This ensures all assessment objectives are examined proportionally, with a strong emphasis on application and analysis.
考试时间、分数和权重都经过了重新校准。例如，在新的 Pre-U 生物学中，试卷一为 2 小时 15 分钟，占总分的 35 %，而试卷二和试卷三各为 2 小时，各占 32.5 %。这确保所有评估目标都按比例考察，并特别强调应用与分析。
3. Greater Emphasis on Practical Skills | 对实践技能的进一步强调
One of the most significant shifts for 2026 is the enhanced status of practical competencies. Instead of a standalone practical endorsement that merely records activities, practical skills are now explicitly examined through written papers. Candidates must demonstrate their understanding of experimental design, data analysis, error evaluation, and the use of apparatus.
2026 年最显著的变化之一是实践能力地位的提升。实践技能不再仅仅是记录活动的独立实践认证，而是现在明确通过笔试试卷来考察。考生必须展示他们对实验设计、数据分析、误差评估以及仪器使用的理解。
The new ‘Practical Skills and Synoptic Assessment’ paper integrates laboratory-based questions with broader synoptic themes. Questions may describe unfamiliar experimental scenarios and ask students to critique methodology, suggest improvements, or process raw data. This mirrors the approach of university science examinations and rewards deep practical insight.
新的“实践技能与综合评估”试卷将基于实验室的问题与更广泛的综合性主题相结合。题目可能会描述不熟悉的实验场景，并要求学生评论方法、提出改进建议或处理原始数据。这反映了大学科学考试的方法，并奖励深入的实践洞察力。
4. Integration of Mathematical Skills across Sciences | 跨科学学科的数学技能整合
In line with increased quantitative expectations, the 2026 Pre-U sciences embed mathematical techniques more thoroughly. For Biology, around 10 % of all marks require mathematical handling, including statistical tests like the Chi-squared test and the t-test, logarithmic relationships, and calculation of rates and uncertainties. In Chemistry, mathematical competencies extend to pH calculations, thermodynamic expressions, and graphical analysis.
鉴于定量要求的提高，2026 年 Pre-U 科学更彻底地嵌入了数学技术。在生物学中，约 10 % 的分数要求数学处理，包括卡方检验和 t 检验等统计检验、对数关系以及速率和不确定度的计算。在化学中，数学能力扩展到 pH 计算、热力学表达式和图形分析。
Physics, historically the most mathematical of the three, now formally integrates topics such as complex numbers, matrix operations, and differential equations in optional sections. All subjects provide a clear list of mathematical requirements in the specification, enabling teachers to plan cross-curricular support.
物理学历来是三者中数学化程度最高的，现在正式在选修部分中融入了复数、矩阵运算和微分方程等主题。所有科目都在教学大纲中提供了明确的数学要求列表，使教师能够规划跨学科支持。
5. Synoptic Assessment and Holistic Understanding | 综合性评估与整体理解
Synopticity is a hallmark of the Pre-U philosophy, and 2026 syllabuses intensify this feature. Learners are expected to draw together knowledge from different topics to solve complex problems. For instance, a Biology question might require integrating genetics, physiology, and evolution to discuss antibiotic resistance.
综合性是 Pre-U 理念的一个标志，2026 年的教学大纲强化了这一特色。学习者需要将来自不同主题的知识结合起来解决复杂问题。例如，一道生物学题目可能需要整合遗传学、生理学和进化论来讨论抗生素耐药性。
This synoptic demand is not confined to a single paper. Across all three components, questions are designed to cross topic boundaries. The final paper in each subject is explicitly synoptic, bringing together core concepts and practical applications in ways that mirror real-world scientific inquiry.
这种综合性要求并不局限于某一份试卷。在所有三个组成部分中，题目的设计都跨越了主题界限。每门科目的最后一份试卷明确是综合性的，以反映现实世界科学研究的方式将核心概念和实际应用结合在一起。
6. Updated and Modernised Content | 更新与现代化的内容
Each science subject has undergone a careful content refresh to reflect advances since the previous specifications were introduced. In Biology, topics now include epigenetics, bioinformatics, and the role of microbiomes. Chemistry has expanded coverage of spectroscopic techniques, nanomaterials, and sustainable processes. Physics incorporates detectors at CERN, gravitational wave astronomy, and advances in solid-state physics.
每门科学科目都经过了精心的内容更新，以反映自上一版教学大纲推出以来取得的进展。在生物学中，主题现在包括表观遗传学、生物信息学和微生物组的作用。化学扩展了光谱技术、纳米材料和可持续工艺的内容。物理学则融入了欧洲核子研究组织的探测器、引力波天文学以及固态物理学的进展。
