这种额外的深度极受大学重视，使 Pre-U 成为学位水平学习的理想预备。然而，学生必须核实心仪大学是否明确列出与 A-Level 并行的 Pre-U 要求。

3. General Recognition by UK Universities | 英国大学对 Pre-U 资格的总体认可度

All UK universities that accept A-Levels also accept Cambridge Pre-U qualifications. According to UCAS, Pre-U grades are assigned tariff points, and most universities articulate Pre-U offer conditions in terms equivalent to A-Level grades. The flexibility of the Pre-U principal subject structure allows students to present combinations such as three Pre-U principal subjects or a mix with A-Levels.

所有接受 A-Level 的英国大学也都接受 Cambridge Pre-U 资格。根据 UCAS，Pre-U 成绩被赋予 tariff points，多数大学以等同于 A-Level 等级的方式表述 Pre-U 的录取条件。Pre-U 主要科目结构的灵活性允许学生提交三个 Pre-U 主要科目或与 A-Level 混合的组合。

It is common to see offers expressed as ‘D3 in Chemistry and two other Pre-U principal subjects’ or ‘D3, D3, M1 including Chemistry’. Always consult the course entry requirements on university websites.

常见的录取条件表述为‘化学及另外两门 Pre-U 主要科目 D3’或‘包括化学在内的 D3, D3, M1’。务必查阅大学网站上的课程入学要求。

4. Typical Entry Requirements for Chemistry Degrees | 化学学位典型入学要求

For competitive Chemistry courses, typical Pre-U offers range from D3, D3, D3 to D2, D3, D3, with Chemistry required at a specific grade. The following table illustrates requirements from a selection of universities for BSc/MSci Chemistry or Chemistry-related programmes.

对于竞争激烈的化学课程，典型的 Pre-U 录取条件从 D3, D3, D3 到 D2, D3, D3 不等，并要求化学达到特定等级。下表展示部分大学对化学本科/化学硕士或相关课程的入学要求。

请注意，部分大学可能要求完成 Pre-U 文凭中的全球视野与独立研究 (GPR) 部分，但这通常不是化学专业的强制性要求。

5. UCAS Tariff Points for Pre-U Chemistry | Pre-U 化学的 UCAS 分数换算

The UCAS tariff system assigns points to different grades, helping universities compare qualifications. For Pre-U Principal Subjects, the tariff is:

UCAS 分数系统为不同等级分配点数，帮助大学比较各种资格。Pre-U 主要科目的分数如下：

Grade	Capped Tariff Points (2024)
Distinction 1 (D1)	56
Distinction 2 (D2)	56
Distinction 3 (D3)	52
Merit 1 (M1)	44
Merit 2 (M2)	36
Merit 3 (M3)	28
Pass 1 (P1)	24
Pass 2 (P2)	20
Pass 3 (P3)	16

In practice, research-intensive universities rarely use tariff points to set offers; instead they specify grades in the subjects relevant to the course.

实际上，研究型大学很少使用 tariff points 来设定录取条件；它们通常直接指定与课程相关科目的成绩等级。

6. Typical Offer Conditions Involving Pre-U Chemistry | 涉及 Pre-U 化学的典型录取条件

Offers for Chemistry degrees often require a minimum of D3 in Pre-U Chemistry. Highly selective programmes may ask for D2 or even D1 alongside strong performance in other subjects. For example, an offer from a top university might read: ‘D2, D3, D3 in three Pre-U principal subjects, to include Chemistry at D2, and a pass in the GPR’.

化学学位的录取条件通常要求 Pre-U 化学至少达到 D3。高选择性课程可能要求 D2 甚或 D1，并辅以其他科目的优秀成绩。例如，一所顶尖大学的录取条件可能是：‘三门 Pre-U 主要科目 D2, D3, D3，其中化学要达到 D2，并需要 GPR 通过’。

It is essential to note that achieving the minimum offer is no guarantee of admission; personal statements, references, and admissions tests (e.g., the NSAA at Cambridge for Natural Sciences, though Cambridge no longer uses Pre-U as a main currency, prefer A-Level) also play a crucial role.

需注意，达到最低录取条件并不能保证录取；个人陈述、推荐信和入学测试（例如剑桥自然科学专业的 NSAA，但剑桥现已不将 Pre-U 作为主要入学币种，更偏好 A-Level）也起着关键作用。
