For students and parents preparing applications for engineering or science courses at Oxford, Cambridge, and Imperial College London, the names PAT (Oxford Physics Aptitude Test) and ESAT (Engineering and Science Admissions Test) will likely ring a bell. These are crucial ‘acid tests’ used by these top-tier institutions to select applicants for their science and engineering disciplines.
A common question naturally arises, particularly for those students and parents aiming for engineering or physics programmes at both Oxford and Cambridge/Imperial College: Given that both are science and engineering-related examinations, how significant are the differences between ESAT and PAT? If my child needs to prepare for both, is there an efficient way to combine their preparation? Or are they entirely distinct, requiring separate and independent study?
Admittedly, not all science applicants will need to tackle both examinations. For instance, those applying for courses in chemistry or biology-related fields (ESAT is required for Chemical Engineering and Biotechnology, biological streams of Natural Sciences, and Veterinary Medicine at Cambridge) or materials science (PAT is required for Oxford) typically only need to prepare for one.
This article will delve into the core similarities and differences between the ESAT and PAT examinations. Our aim is to clarify the landscape for all students and parents interested in ESAT and PAT. Specifically for those needing to prepare for both – students applying for engineering or physics – we will focus on analysing the ‘correlation’ and ‘differences’ in their preparation, offering an effective combined strategy. For students who only need to take one examination, this comparison will also provide a deeper understanding of the unique aspects of the exam they face, thereby enabling more targeted preparation.
First, let’s condense the key information about ESAT and PAT into a table. This will allow you to quickly grasp their overall structure and core differences.

Summary
As the table above illustrates, both ESAT and PAT are online, multiple-choice examinations administered by Pearson VUE, aimed at applicants for top university science and engineering courses, and neither requires knowledge of Further Mathematics. However, they differ in the breadth of subjects covered (ESAT is broader), whether they are modular (ESAT is), calculator policies, and the final presentation of scores (standardised score vs. raw score).
Having grasped the core information, let’s now delve into the feasibility of preparing for ESAT and PAT concurrently, highlighting key areas that demand particular attention.
For students aiming to tackle both examinations (specifically those selecting the Mathematics 2 + Physics modules for ESAT), a combined preparation strategy is indeed feasible. This is primarily due to the following commonalities:
Overlapping Mathematical and Physics Knowledge
The content required for ESAT’s Mathematics 1, Mathematics 2, and Physics modules significantly overlaps with the A-Level/GCSE Mathematics and Physics knowledge needed for PAT. This means that when revising core topics such as functions, mechanics, electricity, and basic calculus, you can effectively ‘kill two birds with one stone.’
Shared Skillset
Both examinations place considerable emphasis on a student’s logical-mathematical reasoning, their ability to apply scientific principles to solve practical problems, and their capacity to maintain clear thinking and accuracy under pressure. Honing these core scientific literacies will benefit performance in both tests.
Similar Format
Both are online multiple-choice examinations administered via the Pearson VUE platform. Familiarity with the computer-based testing environment, on-screen reading, and multiple-choice answering techniques is transferable between the two.
Despite these commonalities, it’s crucial not to treat ESAT and PAT as interchangeable. You must clearly recognise and specifically address the following key distinctions:
ESAT’s Modularity and Breadth
ESAT is structured into five modules: Mathematics, Physics, Chemistry, and Biology. Students must select and prepare for three of these, guided by their university application requirements. This implies a potentially broader knowledge base (particularly if Chemistry or Biology is chosen). Furthermore, during the exam, students will need to swiftly switch between different subject mindsets and manage their time effectively within the independent 40-minute slots allocated to each module.
PAT’s Integration of Physics and Mathematics, and Depth
While PAT only tests Physics and Mathematics, it strongly emphasises their deep integration in problem-solving. Questions may be more comprehensively and ingeniously designed, potentially demanding a more profound understanding of physical concepts and a more versatile application of mathematical tools.
Fundamental Difference in Calculator Policy
This is a critical distinction requiring careful attention:
Differing Emphasis on Speed
ESAT allocates 40 minutes for 27 questions per module, averaging roughly 1.5 minutes per question. This demands exceptionally rapid knowledge retrieval and reaction speed. PAT, while also multiple-choice and with a total duration of 2 hours for 40 questions (averaging about 3 minutes per question), might appear slightly more relaxed. However, its questions may require more time for thorough reading, comprehension, modelling, and calculation (especially when using the online calculator). Consequently, it places equally high demands on depth of thought and problem-solving efficiency.
Having clarified the similarities and differences, we can now formulate an effective preparation strategy, particularly for students requiring combined preparation.
The ‘effectiveness’ of combined preparation primarily stems from integrating common foundations. It is especially applicable to students whose application pathways cover related courses at Oxford and Cambridge/Imperial College, and who select the Mathematics and Physics modules for ESAT. Consolidating the revision of core mathematical and physical knowledge can effectively save time. However, please remember that the realisation of this efficiency must be predicated on precise, differentiated training.
Step One: Confirm Modules and Self-Assess
Firstly, confirm that your chosen course requires or allows the selection of ESAT’s Mathematics 2 and Physics modules! This is the prerequisite for combined preparation. Secondly, objectively assess your proficiency in Mathematics, Physics (and other ESAT elective subjects), and your abilities both with and without calculator assistance.
Step Two: Consolidate Common Foundations
Systematically revise and consolidate the overlapping A Level Mathematics and Physics core knowledge points. Focus on conceptual understanding and mastery of fundamental principles.
Step Three: Differentiated Specialist Training
ESAT Specialist Training
PAT Specialist Training
Step Four: Simulate and Adjust
Periodically undertake full online mock examinations for ESAT (according to module combinations) and PAT, strictly adhering to time and calculator rules.
Based on mock examination results, analyse areas of weakness and promptly adjust revision priorities and training strategies.
Recommended Preparation Time
Considering the breadth of knowledge involved and the training of two different skill sets (particularly regarding calculators), it is advisable to allocate at least 5 months for systematic preparation. It is crucial to start early and ensure consistent, sustained effort.
Official Resources are Fundamental
The official ESAT and PAT websites, syllabuses, sample questions, and online practice platforms are fundamental resources that must be fully utilised.
Key Recommended Resources
Platforms such as Isaac Physics are beneficial for enhancing general mathematical and physical abilities.
Considering the unique nature of combined preparation, selecting courses and materials specifically designed for the characteristics of both ESAT and PAT will be significantly more effective. For example, the ESAT + PAT On-Demand Prep Suite and ESAT + PAT Live Classes offered by UEIE.
ESAT & PAT On-Demand Prep Suite
US$593.66 – US$2 355.23
ESAT & PAT Live Classes
US$2 746.38 – US$10 513.91
The greatest value of such resources lies in their optimised learning paths and training content, already structured according to the similarities and differences between the two examinations. They can clearly guide students on what to learn first, what to practise next, and how to practise most efficiently, thereby avoiding the potential waste of time and energy that can result from students figuring things out themselves. For those pursuing efficient preparation, this is a very wise choice.
Combined preparation for ESAT and PAT is feasible, particularly for students primarily targeting engineering and physics disciplines. However, it is by no means an easy undertaking. The key to success lies in acknowledging and effectively addressing the core differences, especially calculator policies and examination style/structure. Planning must be meticulous, and training must be highly targeted; one cannot simply apply ‘one method for two examinations’.
In summary, ESAT and PAT, as gateways to science and engineering courses at their respective top universities, exhibit significant differences in terms of scope, structure, style, and particularly calculator policy, despite both being online multiple-choice examinations. Through the analysis in this article, we hope to have helped you clarify their core similarities and differences.
For applicants, whether focusing on one examination or needing to tackle both, the key to success lies in precisely understanding the requirements of the target examination, planning scientifically, and undertaking targeted, effective preparation.
