What Is the TST?
The UCL Thinking Skills Test (TST) is an admissions assessment used by the Department of European and International Social and Political Studies to help identify applicants with the strongest academic potential. This test is delivered and marked directly by UCL
The TST test is best described as a psychometric aptitude test that evaluates your reasoning rather than your subject knowledge. Unlike traditional examinations, there are no specific modules to revise and no additional fee to sit the assessment, as it’s administered directly by UCL as part of the admissions process.
The admissions team uses the test alongside the rest of your application, including your predicted grades, UCAS application and academic profile, to differentiate between large numbers of highly qualified applicants.
Which UCL Courses Require the TST in 2026?
For applicants applying in the 2026/27 admissions cycle, the TST is required for the following programmes within UCL’s Department of European and International Social and Political Studies:
- European Social and Political Studies BA
- International Social and Political Studies BA
- European Social and Political Studies: Dual Degree BA (with Sciences Po)
Together, these three EISPS programmes combine politics, economics, history and languages to create an interdisciplinary social science subject. Whether you’re applying for a Social and Political Studies degree or the dual degree with Sciences Po, the TST forms a compulsory part of the entry requirements.
Applicants to the Dual Degree programme who perform strongly in the TST may also be invited to attend an online interview conducted by Sciences Po as part of the admissions process.
TST Registration and Key Dates (2026)
Unlike the ESAT, TMUA and TARA, the UCL Thinking Skills Test (TST) is administered directly by UCL. After submitting your UCAS application, you’ll need to register for the assessment using the department’s online registration form. UCL will email eligible applicants with full registration instructions.
For the 2026–27 admissions cycle, applicants can choose from one of the following testing weekends:
| Test Window | Assessment Dates |
|---|---|
| Test Window 1 | 17–18 October 2026 |
| Test Window 2 | 14–15 November 2026 |
| Test Window 3 | 12–13 December 2026 |
| Test Window 4 | 16–17 January 2027 |
| Test Window 5 | 20–21 February 2027 |
Tests are available from 12:00 noon on Saturday until 12:00 noon on Sunday, allowing applicants to choose a convenient time within their selected weekend.
Once you’ve received your invitation, don’t delay your registration. Test places are allocated through UCL’s booking system, so it’s sensible to register early and select the testing window that best fits your preparation schedule.
Before sitting the assessment, make sure you’ve read all of UCL’s instructions carefully and checked that your computer and internet connection meet the technical requirements for the online test.
How to Prepare for the TST UCL
If you’re wondering how to prepare for the TST UCL, you’ve come to the right place. Below, we’ll walk you through the preparation strategies our UCL Admissions Tutors recommend to help students maximise their performance.
1. Familiarise Yourself with the TST Format
For the 2026–27 admissions cycle, the current TST format mirrors Section 1 of the former Thinking Skills Assessment (TSA) from Cambridge Assessment Admissions Testing. Candidates have 90 minutes to complete 50 multiple-choice questions designed to assess problem-solving and critical thinking skills alongside your ability to understand arguments.
Questions are based on short passages of text, tables, charts and other information. You’ll be asked to evaluate arguments, identify assumptions, interpret evidence, draw logical conclusions and solve numerical or spatial reasoning problems. The test is designed to assess how well you think under pressure, not how much you’ve memorised.
The assessment covers two broad skill areas:
- Critical Thinking – evaluating arguments, recognising assumptions, identifying conclusions and assessing evidence.
- Problem Solving – interpreting numerical information, recognising patterns and applying logical reasoning to unfamiliar situations.
Unlike the former Oxford TSA, there is no essay or written component. Instead, the entire assessment consists of a single multiple-choice paper, making time management and accuracy particularly important.
2. Build Your Critical Thinking Skills
The TST is designed to assess not only how you think, but how well you maintain accuracy under pressure. Questions may include unnecessary details or distracting information to test whether you can identify what matters, prioritise evidence and reach conclusions efficiently.
The difficulty of the questions may also vary throughout the test rather than increasing in a predictable order. Later questions can feel more challenging simply because you have less time remaining and your concentration is beginning to dip.
That is why it is essential to practise reducing each TST question to its core components. Our Undergraduate Admissions Tutors recommend the following approach:
- Start by reading the question prompt. The prompt is usually a single sentence that tells you exactly what you’re being asked to do and typically follows a passage presenting an argument or problem. For example, you may be asked to identify the main conclusion, an underlying assumption or the answer that most closely parallels the reasoning in the passage.
- Once you understand the task, simplify the argument into its basic components. Identify the central conclusion, supporting premises or key variables before attempting the answers. Reducing the argument to its most basic form makes it much easier to compare the available options and avoid being distracted by irrelevant details.
- Work through the answer choices systematically. Identify the underlying reasoning in each option and assess whether it mirrors the logic of the original passage before making your final choice. Eliminating incorrect answers one by one is often more effective than trying to spot the correct answer immediately.
- Keep moving and manage your time effectively. With 90 minutes to answer 50 multiple-choice questions, you’ll have less than two minutes per question. Practise with a timer so you become comfortable working under realistic conditions, and don’t spend too long on any single question. If you’re unsure, eliminate any obviously incorrect answers, make your best-informed choice and move on. Questions involving graphs, tables or lengthy passages often contain red herrings, so train yourself to identify the key information as quickly as possible.
3. Develop Your Maths & Problem-Solving Skills
4. Use TSA Past Papers to Prepare
Because the TST follows the same format as Section 1 of the Thinking Skills Assessment (TSA), TSA Section 1 past papers remain one of the best preparation resources available. Previously used by Oxford, the TSA contains a wide variety of questions assessing critical thinking, problem-solving and logical reasoning – the same core skills that UCL expects applicants to demonstrate.
As you work through TSA past papers, don’t worry if your scores are initially lower than expected. The objective isn’t simply to achieve a high mark straight away but to develop stronger analytical thinking over time.
After every practice paper:
- Review every incorrect answer.
- Identify why the correct answer was right.
- Understand why the remaining options were wrong.
- Look for recurring patterns in your mistakes.
While TSA Section 1 should remain your primary resource, don’t overlook other reasoning-based admissions tests. BMAT Section 1 is particularly useful because, like the TST, it assesses critical thinking and problem-solving rather than curriculum knowledge. Working through BMAT Section 1 questions can help broaden your exposure to different reasoning styles and further develop the analytical skills needed to perform well in the TST.
A bonus preparation tip from Richard Evans, Founder of The Profs, Forbes 30 Under 30 recipient and one of the UK’s leading admissions tutors:
Where Can You Find TST Practice Questions?
Many of the reasoning skills assessed by the TST closely mirror those tested by previous university admissions exams, giving applicants access to a wealth of high-quality practice resources, including:
- TSA Section 1 past papers – The closest publicly available resource for developing the critical thinking and problem-solving skills assessed in the TST.
- BMAT Section 1 papers – Although originally designed for medical applicants, Section 1 focuses on aptitude, problem-solving and numerical reasoning rather than scientific knowledge, making it an excellent source of additional practice.
- GMAT Critical Reasoning questions – Particularly useful for strengthening your ability to identify assumptions, summarise arguments and recognise conclusions in complex passages of text.
- Official TSA question banks and specimen papers – Ideal for building familiarity with different styles of reasoning questions before attempting a full mock test.
FAQs About the TST at UCL to Help You Prepare
Is the TST the Same as the TSA?
Not exactly. The TST isn’t a completely new assessment; it follows the same format as Section 1 of the former Thinking Skills Assessment (TSA). While the reasoning skills and question types remain the same, the assessment is now delivered and marked directly by UCL as part of its own admissions process.
Although many applicants still search for the TSA UCL or wonder whether they need to take the TSA, the university has introduced the TST as the assessment for these degree programmes. If you’ve been preparing using TSA Section 1 papers, you’re using the right resources, as they remain the closest publicly available representation of the TST.
How Long Should I Spend Preparing for the TST?
At The Profs, we typically recommend around 10 hours of one-to-one tutoring, usually delivered as one hour per week over two to three months. This gives your tutor enough time to assess your existing reasoning skills, identify your strengths and weaknesses, teach effective exam techniques and track your progress through timed practice.
Consistency is more important than the total number of hours studied. Completing regular practice sessions, reviewing your mistakes carefully and sitting realistic practice tests is generally far more effective than cramming immediately before the assessment.
A structured preparation programme should combine official test materials, sample questions, timed mock papers and detailed feedback after every session. Spreading your test preparation over several weeks allows you to gradually improve your speed, accuracy and confidence while becoming familiar with the TST format.
How Important Is the TST?
The TST forms an important part of the admissions process for the courses that require it. It helps UCL distinguish between applicants with similarly strong academic profiles by assessing skills that aren’t always reflected in predicted grades or personal statements.
For competitive degree courses, including European Social and Political Studies and International Social and Political Studies, the assessment helps the admissions team identify students with the analytical ability needed to succeed on these multidisciplinary programmes.
A strong score can significantly strengthen an already competitive application and demonstrate your problem-solving and critical thinking ability alongside the rest of your UCAS application.
Can a TST Tutor Improve My Score?
Yes. Working with an experienced tutor can help you prepare more efficiently by identifying weaknesses in your reasoning, improving your approach to different question types and providing detailed feedback on practice papers.
At The Profs, our admissions tutors deliver personalised preparation programmes tailored to each student’s strengths, helping applicants develop the critical thinking skills needed to perform confidently on the TST and strengthen their overall UCL application.
Your tutor can also recommend the most effective ways to prepare, explain what constitutes a competitive score for your chosen course, and guide you through high-quality resources such as TSA Section 1, BMAT Section 1 and GMAT Critical Reasoning questions. With expert feedback and structured preparation, you’ll approach the assessment with a clear strategy and greater confidence.
