“The new [Medibuddy] adaptive UCAT question bank made my revision much more efficient and it helped me get better and quicker at answering questions”

“I used the Abstract Reasoning section as I found the website the night before my test and I was pretty bad at AR. In my official exam my AR was my 2nd best section at 860! Overall, I thought the website was a very useful resource from what I saw and I liked the algorithm that showed skill in particular question types.”

Why use the Medibuddy adaptive UCAT question bank?

Did you know that if you spend an average of 2 minutes answering and absorbing the explanation of each question in a question bank, it will take you 333 hours to get through 10k questions!?

No wonder the vast majority of people don’t answer anywhere near 10k questions before their exam!

We surveyed 100s of medical students and asked them what their biggest issue was when preparing for the UCAT.

Over 90% said that because the UCAT wasn’t a knowledge-based exam, they could answer thousands of questions but never feel like they were getting anywhere.

The trouble with standard question banks is that everyone is given the same questions to prepare with, with no consideration of what skills or topics each person is actually struggling with.

However, everyone has a different baseline ability. You might struggle with quantitative reasoning, whereas your friend might be a maths wizard. With a standard question bank, you’ll both answer the same QR questions, in the same order, meaning you’ll be left struggling while your friend doesn’t feel stretched.

No wonder so many people can find preparing for the UCAT frustrating!

The Medibuddy adaptive UCAT question bank is here to change all that.

We recognise that the vast majority of students don’t complete all 10,000 questions in a question bank.

It’s therefore vitally important that the questions you do answer are relevant to your skill and ability level.

We’ll ensure that in the areas you’re struggling, you’ll master the basics first. Whereas in your stronger areas, you’ll be immediately pushed.

This will mean that every minute of your revision is turbo charged to maximise your UCAT score.

More than a just question bank that tells you the correct answers

As you progress through the question bank, you’ll be able to see a sophisticated estimate of your current skill level for each subsection of the UCAT. When other question banks give you a performance review, they are simply telling you how many questions you’ve got right or wrong. 

We do things differently.

Our algorithm will tell you exactly what your ability level is for each area of the UCAT. We calculate this based on the actual difficulty of the questions you are answering and it’s done in real time, so you can be sure that the work you’re putting in is actually translating into real gains in your UCAT score.

The Medibuddy UCAT question bank is the only one available which shows you if you’re actually getting better at answering harder questions.

First introduced in 2016 to replace the Decision Analysis subtest, the UCAT Decision Making subtest assesses your ability to analyse information and apply logic to make decisions.

This guide will provide you with more information about the Decision Making subtest, including how to prepare, tips to do well and where to access free quality UCAT practice questions.

What does UCAT Decision Making test?

The UCAT Decision Making subtest assesses your ability to evaluate arguments, analyse statistical information and apply logic to make decisions or form conclusions. The questions relate to information presented in text, charts, tables, graphs and diagrams.

Why is there a UCAT Decision Making subtest?

The ability to make decisions is an essential skill for doctors. Often they are tasked with doing so in complex situations where they’re required to assess and manage risk, deal with uncertainty and apply high-level problem solving skills.

Being able to reason, evaluate arguments for and against, and use logic are key skills for problem solving.

UCAT Decision Making format

As mentioned previously, questions in this subtest relate to data which is provided in text, charts, tables, graphs or diagrams. For some questions, you will have to select the correct answer from 4 possible answers, while in others, you have to respond to 5 statements with ‘yes’ or ‘no’.

How many questions in Decision Making?

There are 29 questions in the UCAT Decision Making subtest. All questions are standalone and do not share data.

How long is Decision Making?

You’ll have 31 minutes (plus a 1 minute instruction section) to answer the 29 questions, giving you approximately 1 minute per question.

UCAT Decision Making questions

There are six types of questions within the UCAT Decision Making subtest, they are:

  1. Logical puzzles
    • Using the information given and applying one or more steps of ‘deductive inference’ to arrive at a conclusion.
    • There is one correct answer per question.
    • Information will be presented in text, tables or other graphics.
  2. Syllogisms
    • You’ll be provided with information, from which you will need to evaluate whether each of the 5 conclusions could arise.
    • You need to respond ‘yes’ or ‘no’ to each of the 5 statements.
  3. Interpreting information
    • You need to interpret the information provided to determine whether the conclusions are correct.
    • You need to respond ‘yes’ or ‘no’ to each of the 5 statements.
    • Information will be presented in various ways, including text, graphs and charts.
  4. Recognising assumptions
    • You’re required to evaluate arguments for and against a particular solution to a problem, as well as the strength of the arguments.
    • There is one correct answer per question.
  5. Venn diagrams
    • You may be presented with information in a Venn diagram and asked to select the best conclusion from a list of statements.
    • Alternatively, you may be presented with information in a passage and asked to select the Venn diagram that best represents the information from a selection.
    • There is one correct answer per question.
  6. Probabilistic reasoning
    • You’ll be given statistical information presented in a short passage and asked to select the best response to the questions.
    • There is one correct answer per question.

You can find strategies for each question type in the relevant section below.

How do you answer UCAT Decision Making questions?

As mentioned above, there are two answer types within the UCAT Decision Making subtest:

  1. Multiple choice answers
    • For these questions you must select the correct answer from 4 possible options.
    • The logical puzzles, recognising assumptions, Venn diagrams and probabilistic reasoning questions all use this answer type.
  2. ‘Yes’ or ‘no’ answers
    • For these questions you’ll be given 5 statements for which you need to answer ‘yes’ or ‘no’ depending on their accuracy.
    • The syllogisms and interpreting information questions use this answer type.

The strategies section below gives more information on how to approach each of these question types.

UCAT Decision Making scoring

Within the Decision Making subtest, scoring depends on the type of question. For the multiple choice questions, which have one correct answer, one mark is available for each. For the ‘yes’ or ‘no’ questions, which have five statements to respond to, there are two available marks; two marks will be awarded for all correct responses to the statements and one mark for partially correct responses.

The raw mark you achieve in the Decision Making subtest is converted into a ‘scale score’ between 300 – 900. The other cognitive subtests – Abstract Reasoning, Quantitative Reasoning and Verbal Reasoning – are all scored in the same way, whereas the Situational Judgement Test is scored using a band system.

What is an average score for UCAT Decision Making?

The UCAT website provides the following data for 2018 – 2023 exams:

Year Number of candidates Mean scaled score
2018 27,466 624
2019 29,375 618
2020 34,153 625
2021 37,230 610
2022 36,374 616
2023 35,625 623

For more information about how the UCAT is scored, including the scaled scoring, visit our UCAT Score and UCAT Decile Ranking blogs.

What is a good score for UCAT Decision Making?

For all of the ‘cognitive subtests’ in the UCAT, it’s generally advised that a ‘good’ score is approximately 20 – 30 marks above the average score for that subtest. For example, for 2023, a ‘good’ UCAT score for the Decision Making subtest would be 643 – 653.

Remember, the average score will vary each year, depending on how that year’s candidates perform, and therefore, so will what’s considered a ‘good’ UCAT score.

Is UCAT Decision Making hard?

Decision Making can be a tricky section of the UCAT with some questions which can easily trip candidates up. Remember, your score for each of the cognitive subtests – Verbal Reasoning, Decision Making, Quantitative Reasoning and Abstract Reasoning – will be combined to give you a total UCAT score. So it’s worthwhile dedicating time to all areas of the exam, particularly those which you find more challenging, as these have the potential to bring your score down.

The free, adaptive Medibuddy UCAT question bank can help you to easily identify the areas which you need to improve and uses artificial intelligence to provide personalised learning based on your individual strengths and weaknesses. By taking this more focused approach to your UCAT revision, you’ll see more improvement in your UCAT performance and the score you achieve.

How to prepare for UCAT Decision Making

Preparing for UCAT Decision Making Test

As mentioned previously, some of the questions in the Decision Making subtest can be tricky if you’re unsure of them; therefore, it’s vital that you’re familiar with the types of questions you’ll receive and how to answer them. Focusing on practice questions and practice tests during your UCAT preparations will support you in understanding what the subtest involves and how to approach it.

To ensure that you’re fully prepared for the exam, you should practice all six types of questions that you'll encounter. In addition to this, to gain more from your preparations, you should aim to identify the types of questions you find more challenging and dedicate additional time to those. The free, adaptive Medibuddy question bank automatically identifies these for you and ensures that you spend time developing the areas which are likely to have the biggest impact on your UCAT Decision Making score.‍

You’ll find more information about practice questions, and the free Medibuddy question bank in the questions section.

As well as practice questions and tests, brushing up on your maths skills will help you with the Decision Making section. The UCAT website suggests that you specifically focus on revising probability and Venn diagrams, which are needed for the probabilistic reasoning and Venn diagrams questions.

Strategies for UCAT Decision Making

The UCAT Question Tutorial provides the following strategies for answering questions in the UCAT Decision Making subtest:

  • Logical puzzles
    • Work out the correct placement of facts first and use this known position as a reference to pinpoint other positions.
    • You might find it helpful to write or draw this information; you’ll be provided with a notebook and pen for this.
    • You may also find it useful to eliminate answers that can’t be correct first.
    • Look at the language and how this affects the question, for example, ‘must’ vs ‘might’.
    • Not all information may be relevant; avoid wasting time working out elements that aren’t required.
  • Syllogisms
    • Read the information carefully and consider each conclusion in turn.
    • Avoid assumptions and use only the information provided.
    • Don’t be put off by the occasional use of made up words.
    • Again, pay attention to the language used, particularly words such as ‘all’, ‘some’, ‘none’ and ‘only’.
  • Interpreting information
    • In some cases, you may be presented with a lot of information in graphs or charts – focus on what you can interpret from this information.
    • Remember to only use the information provided, not prior knowledge, and adopt reasoning skills to work out the answers. Does the information support the conclusions?
    • Similarly, don’t judge the strength of a conclusion by its plausibility.
    • Use simple maths techniques, such as rounding numbers, to speed up working out answers.
  • Recognising assumptions
    • Use the information provided to reach a conclusion; don’t use your own beliefs or existing knowledge to answer.
    • You need to select the strongest argument. Strong arguments will be those directly connected to the subject matter, whereas weak arguments will rely on assumptions or opinions. Therefore, eliminate statements that are based on assumptions, not facts.
  • Venn diagrams
    • Include Venn diagram revision in your preparations.
    • Read the information carefully and eliminate answers which can't be correct.
    • Not all information may be relevant; avoid wasting time working out elements that aren’t required.
  • Probabilistic reasoning
    • Include probability revision in your preparations.
    • Read the information carefully and consider each of the possible options in turn.
    • You may also find it useful to eliminate the options that can’t be correct first.
    • You don’t need advanced statistical knowledge to answer; you just need to apply practical reasoning to the statistical data.

For logical puzzles and syllogisms in particular, which refer to the type of language being used, the UCAT website provides ‘Decision Making definitions’ which clarify the key language used in the subtests.

4 top tips for UCAT Decision Making

The following tips will support you to perform well during the UCAT Decision Making subtest:

  • Use the information provided
    The Decision Making subtest requires you to use logic to arrive at a decision or conclusion; however, as mentioned in the strategies for some of the subtests, this should be applied to the information provided only, and you should avoid drawing upon your prior knowledge. The UCAT website suggests that you may need to ‘suspend your own beliefs and biases when making decisions’ to ensure that they don’t influence your conclusions.
  • Practice using the test functions
    You can practice using the UCAT test functions, including dragging and dropping the correct responses used in the ‘yes/no’ questions and the onscreen calculator, with the UCAT tour tutorial. It’s useful to familiarise yourself with the test functions to ensure that you can easily navigate the test and avoid wasting time during the exam.
  • Use the tools provided, where required
    During the Decision Making subtest, you’ll be provided with an onscreen calculator and a notebook and pen, which can be useful during this section of the UCAT. Make the most of these when you need them, but avoid using them unnecessarily, as it can slow you down and waste time during the exam.
  • Use the ‘flag’ function, where needed
    The ‘flag’ function allows you to mark a question so you can easily return to it later, if you have time during the exam. We recommend always using the ‘flag’ function and guessing an answer, rather than leaving it blank, if you’re unsure of a question. As with all sections of the UCAT, the Decision Making subtest is not negatively marked, so it’s more beneficial to guess an answer than leave it blank, and flagging allows you to return to the question if you have time.

UCAT Decision Making practice questions

Completing practice questions and practice tests is the most effective way of preparing for the UCAT. They allow you to become familiar with the types of questions you’ll be asked and how to answer them, which will increase your pace and help you approach the questions more confidently.

The free Medibuddy question bank offers artificial intelligence powered practice questions, which automatically adapt to your strengths and weaknesses, to provide a personalised learning experience. This method of learning makes the most effective use of your UCAT preparation time, as you’ll be guided to spend more time revising the areas which you need to focus on to improve your UCAT score.


Thousands of questions and comprehensive answers written specifically for UCAT preparation, with more getting added.

The Medibuddy platform has been designed to replicate the actual exam, so you won’t get any surprises on the day.

Each question and explanation you receive will be chosen by our AI algorithm, specifically for you.

The only question bank available that tells you if you’re actually getting better and not just how many questions you’ve answered correctly.

We don’t just pick the questions for our mock exams at random, we follow a similar process to the actual exam board by calibrating every question for difficulty, based on the abilities of 100s of medical students. This means your score will be a much more accurate reflection of the real thing.


You can access our platform anywhere and it works on desktops, tablets and phones. This means you can revise at home or on the go.

When the Medibuddy team were preparing for the UCAT, working out where to start was quite overwhelming. The online resources offered thousands of practice questions and lots of generic advice. However, the only way of getting help that was specifically targeted at you was by paying for expensive tutoring.

This didn’t seem right to us. The personalised learning you get with a tutor has been shown to improve exam results across all fields of education. So why when it came to the UCAT, an exam that is vital for medical school, should it only be available to those who could afford a tutor?

The good news is artificial intelligence has changed everything! Super smart algorithms can now identify exactly where your strengths and weaknesses lie, ensuring that every minute of your revision is focused on areas that will have the biggest impact on your exam score.

Here at Medibuddy we’ve used the latest educational technology and combined it with our deep understanding of the UCAT, to produce the first ever AI-powered, adaptive UCAT question bank.

Our sophisticated question bank platform will adapt seamlessly with every question you answer. As you improve, the type and difficulty of the questions you receive will change with you, ensuring that at all times, you only receive the most relevant questions.

A resource you can trust

The Medibuddy team has been creating educational resources for medical students and doctors for years. We’ve helped thousands of students pass their exams and we’ve put all of that experience into our UCAT question bank.

We stay up to date on all the latest educational science, so you can be sure that the techniques we use are state of the art.

How is our UCAT Question Bank free?

We know how expensive applying to medicine can be, so we do our bit by keeping our UCAT question bank FREE.

We’re able to do this by charging a little more on our educational courses and question banks for qualified doctors. We strongly believe that no one should be priced out of medicine. Our doctors agree and are happy to subsidise our educational resources for students.

Frequently Asked Questions

How does the algorithm work out what my ability level is?

As you progress through the question bank, our algorithm will be performing complicated statistical analyses of the way you answer questions. All of our questions have been tested on hundreds of 1st year medical students so the algorithm knows exactly how difficult each question is.

The algorithm looks at how you answer questions across a range of different difficulties to work out what your current ability level is.

How does the algorithm know what questions to give me?

Every question in our database has been tagged based on the skills required to answer it and its difficulty level. Once the algorithm has worked out what your ability level is and the areas you need to target, it ensures that the questions you receive focus on these areas. As you get better, the algorithm adapts with you, moving you onto new areas based on your needs.

How similar to the UCAT are the Medibuddy questions and explanations?

Every single question in our question bank is written specifically for UCAT preparation and is reviewed by our editorial team to ensure it is as close a match as possible to the UCAT standard. We don’t borrow questions that have been written to prepare for other exams. In addition to this, all of our questions are calibrated by 100s of first year medical students who have recently taken the UCAT, which allows us to remove any outliers and ensure consistency.
