Key UCAT Decision Making Strategies for Medical & Dental School Applicants
🤔 Understanding the UCAT Decision Making Subtest
The Decision Making (DM) subtest of the UCAT exam is all about applying logic and reasoning to solve problems. It’s one of the sections used by UK medical and dental schools to assess applicants, so a strong performance can significantly enhance your chances of admission. In the DM section, you’ll face 35 questions in 37 minutes, testing skills like evaluating arguments, drawing logical conclusions, interpreting data, and recognising assumptions. Some questions are standalone multiple-choice, while others present a statement with several Yes/No propositions to evaluate. Crucially, there’s no negative marking, so you won’t lose marks for wrong answers – meaning you should attempt every question, even if it’s a guess.
Why is DM important?
Apart from contributing to your overall UCAT score, Decision Making reflects skills vital to clinical decision-making: the ability to weigh information and reach sound conclusions under time pressure. Below, we’ll break down key strategies to help you master the DM section, improve your speed and accuracy, and approach the test with confidence.
🗺️ Identify the Question Type (Know Your DM Puzzle)
One of the first things to do when tackling a DM question is to identify which question type you’re dealing with. The Decision Making section actually contains a mix of different formats, each with its own quirks and optimal approach. Common DM question types include:
Syllogisms (Logical Deduction): Short arguments with premises that ask if a conclusion follows logically.
Logical Puzzles: Multi-step problems (e.g. scheduling, ordering tasks or people with certain constraints).
Recognising Assumptions: Questions asking which argument or statement has an underlying assumption or which argument is strongest.
Interpreting Information: Analysing information presented in text, charts, tables or graphs to make a decision.
Venn Diagrams: Problems involving set relationships or counting in overlapping categories.
Probabilistic Reasoning: Basic probability questions, sometimes combined with logic or presented as “chance” scenarios.
When a new question appears, spotting the subtype quickly can save you precious time. Each type has “rules” or strategies you can apply. For example, if you recognise a syllogism, you might choose to sketch a quick Venn diagram; if it’s a logic puzzle, you know to jot down the clues in an organised way. In fact, the UCAT consortium itself advises candidates to familiarise themselves with the different question types in Decision Making as part of their preparation. By knowing what to expect and having a plan for each type, you’ll approach questions with the right mindset from the start.

✅ Use Process of Elimination (Eliminate Wrong Answers First)
One of the smartest tactics in DM (and indeed all UCAT sections) is to use process of elimination. Often, it’s easier to identify options that are definitely incorrect rather than immediately spotting the correct one. By eliminating wrong answers, you narrow down the field and increase your odds of selecting the right choice. This strategy is especially useful under time pressure – if you can quickly discard two out of four options, you can focus your analysis on the remaining possibilities.
How do you eliminate effectively? Look out for red flags in the answer choices. For instance, in logical or inference questions, an option that contradicts the given data or goes beyond the information provided can be safely ruled out. In argument evaluation questions, answers containing extreme language (like “always”, “never”) or obvious irrelevancies are likely incorrect. Pay attention to keywords: an answer choice containing words like “might” or “could” indicates uncertainty, whereas “must” or “always” indicates a strong absolute statement. In many cases, a DM question with limited evidence will favour a cautiously worded conclusion (“might be true”) over an overconfident one (“is definitely true”). By spotting these keywords, you can often weed out options that don’t fit the logic of the question.
Also, remember that each DM question is self-contained – all the information needed is on the screen. If an answer option would only be correct by bringing in outside knowledge or assumptions not given, that option should be eliminated. Trust the info in front of you and systematically cross off anything that doesn’t align with it. This approach will not only save time but also guard you against traps and trick answers.
🚫 Don’t Make Assumptions – Stick to the Given Information
A golden rule for the Decision Making section is use only the information provided in the question and avoid making any assumptions beyond that. The test is assessing your logical reasoning based on given data, not your general knowledge. This means if a statement’s truth cannot be definitively determined from the given passage or data, the safest answer is “No” (it does not follow). Conversely, answer “Yes” only if you are certain the conclusion logically follows from the given premises without needing additional assumptions.
This principle is particularly vital for the Yes/No style questions (sometimes called “syllogisms” or deductive reasoning questions). You might be given a short scenario or a few statements, followed by conclusions to evaluate. If a conclusion seems plausible in real life but isn’t explicitly supported by the text, you must treat it as not proven in the context of the exam. As a simple example: if a passage doesn’t mention frogs’ diet at all, a statement that “Frogs are omnivorous” would be “No” (not supported) – even if you happen to know it’s true in reality. However, “Frogs might be omnivorous” could be “Yes,” since the word “might” acknowledges uncertainty and doesn’t contradict the given info.
In assumption and argument questions, put aside your personal beliefs and knowledge. An argument is strong or valid in UCAT terms only if it’s backed by the facts presented, not because it aligns with what you think is true. The Brighton & Sussex Medical School’s official advice to applicants emphasizes this: do not let your own opinions influence your answer – base it purely on the information given. By strictly staying within the scope of the question, you’ll avoid common pitfalls like unwarranted assumptions or jumping to conclusions. Remember: if it’s not written or shown in the question, you can’t assume it.
🧠 Unlock Logic: Think Objectively and Look for Key Details
Success in Decision Making hinges on clear, logical thinking. This means approaching each problem methodically and paying attention to crucial details or keywords that dictate the logic. Here are some key logical strategies and things to watch for:
Recognise Strong vs Weak Arguments:
In questions asking you to pick the strongest argument (often phrased as “Should X do Y?” with arguments for or against), evaluate each option critically. A strong argument is usually objective, evidence-based and directly relevant to the question. For example, it might cite a factual link between a premise and a conclusion or use a clear line of reasoning. A weak argument tends to be subjective or based on assumptions, or it might stray from the point. Ask yourself: Does the premise of this argument directly support its conclusion, or is there a gap? Does it rely on opinion or unverified claims? As a rule of thumb, arguments that include concrete evidence or logical necessity trump those that just “sound reasonable.” In fact, a top tip from admissions advisers is that the strength of an argument isn’t about how agreeable it sounds – it’s about how well it’s supported by facts. So, focus on the logical link: if an argument contains no evidence or has obvious holes in reasoning, it’s likely not the best answer.
Watch for Logical Keywords and Quantifiers:
Certain words drastically affect the meaning of statements. Pay attention to words like “all,” “none,” “some,” “only if,” “unless,” etc. For instance, “All A are B” means every A is B (100%), whereas “Some A are B” means at least one A is B (and potentially more, but not all). The UCAT has specific definitions for these terms (e.g. “some” means at least one but not all), so ensure you understand them in the test’s context. Likewise, qualifiers like “if and only if” or “unless” can flip a statement’s logic on its head – take the time to parse them correctly. A phrase such as “Only doctors can prescribe medication” can be rewritten logically as: “If someone can prescribe medication, then they must be a doctor.” Noting these nuances will help you avoid logical misinterpretations. If needed, translate a sentence into a simpler form or even a quick symbol form (e.g., A → B) to clarify the logic.
Check Every Detail in Data Questions:
When dealing with graphs, tables, or diagrams, read all labels and legends carefully. A tiny detail – like units on a graph’s axes or a note on a diagram – can entirely change the correct answer. Misreading “cm” for “m” or missing that a pie chart segment is labelled “% of patients” could lead you to a wrong conclusion. The question stem will usually direct you to what’s relevant, but it’s on you to catch those details. If a graph-based question asks “What is the best conclusion?”, for example, look at trends and outliers carefully. Make sure you’re interpreting the visual correctly (e.g. increasing vs decreasing) before answering. In decision-making, the accuracy of observation is as important as logical inference, so don’t rush through reading the data.
Beware of Trick Wording:
The examiners sometimes throw in wording that can trip up test-takers who are skimming. Words like “not”, “unless”, “at least”, “at most” and double negatives can cause confusion. Always read the question and answer options slowly enough to grasp them. If a statement says, “No cats are reptiles,” it’s logically equivalent to “All cats are not reptiles.” It might sound obvious, but under time pressure, it’s easy to misread. Another example: “X is not above Y” – does that mean X is below Y, or could X be at the same level? Clarify such phrases in your mind (or on your noteboard) to ensure you understand the constraint properly. Taking a couple of extra seconds to catch a keyword like “not” or “only” can save you from a costly mistake.
🔎 Solving Logic Puzzles – Step by Step
Many Decision Making questions present you with a mini “logic puzzle” – for example, figuring out an order of people or events given some clues, or matching categories to individuals based on conditions. These can look daunting at first, but with the right approach, you can solve them both accurately and efficiently.
Figure: An example of a multi-step logic puzzle question in Decision Making. This question provides several clues about the order of emails in a mailbox and asks how many emails there are between two specific ones. Solving such puzzles requires careful reading and a systematic note-taking approach.
1. Write Down the Key Information:
Don’t try to solve these puzzles purely in your head. Almost every expert suggests using your laminated noteboard (the erasable note pad provided in the exam) to jot down the details. Start by writing out the elements involved (people, items, days of the week, etc.) and any direct clues. For example, if six emails must be ordered and you know “Harry’s email is second from the bottom,” note down a rough order and place Harry accordingly. If “Sarah’s email is not the last,” mark that too. Visualising the problem with a quick sketch, list, or grid prevents you from holding too much in your working memory – freeing your mind to logically deduce the solution. It’s much easier to spot, say, that Claire can only be in two possible positions once you’ve sketched the scenario out.
2. Stay Organised and Consistent:
As you take notes, organise the information logically so you can easily see relationships. One common method is to use a simple grid or table for puzzles involving multiple characteristics (for example, a scheduling puzzle with persons vs. days). Another is to list positions (1st, 2nd, 3rd…) and fill in what you know about each. Use abbreviations or symbols for speed – but be consistent and clear. You might use initials for names (e.g. C for Claire, but ensure no two people share an initial – differentiate like Ca vs Cl if needed- and arrows or “>” for order relations. For instance, if one clue says “X comes before Y”, you could jot “X – Y” as a reminder. The goal is that your notes should make sense at a glance when you refer back. Messy or confusing notes can trip you up, so take a tidy approach even under time pressure. It’s worth the few seconds to clearly lay out what’s what.
3. Start with Simple Deductions:
Tackle the easiest clues first – ones that give definite placements or clear binary restrictions – before wrestling with the more complex conditions. For example, “A is in the last position” or “C must be on Tuesday” can be pencilled in immediately. Each time you place something or rule out an option, see if that revelation triggers another deduction. It’s like a chain reaction: placing A last might now make the clue “A comes directly after B” solvable (meaning B must be second-last). By resolving the low-hanging fruit first, you reduce the puzzle’s complexity and limit the possibilities for the remaining unknowns. This prevents you from getting entangled in unnecessary complications early on.
4. Use Clue Keywords to Infer Order:
Puzzles often include terms like “before”, “after”, “next to”, or “between”. These are your guides to constructing the order. For instance, if you read “The brick house comes after the wooden house,” you know the wooden house cannot be last, and the brick house cannot be first. Clues that state “two items between X and Y” or “X is immediately adjacent to Y” should be clearly noted (maybe underline “immediately” vs “not immediately” as appropriate). These relational phrases can sometimes be combined: if X is before Y and Y is before Z, then X is also before Z (transitive logic). Look out for such links between clues.
5. Double-Check and Don’t Erase Workings:
If you’ve placed elements but haven’t solved the puzzle entirely, don’t erase your work in frustration. There may be partial deductions that will help when you return to the question. It’s not uncommon to get stuck momentarily; if time permits, you can flag the question, move on, and come back later with fresh eyes. When you do, those notes will save you from having to restart from scratch. The exam gives you a fresh noteboard, and you can always request more if needed, so use the space freely to lay out everything.
Finally, practice a method that works for you. Some people love drawing quick diagrams or even little sketches for puzzles (like drawing six email envelopes in a vertical order, labelling them as they deduce positions). Others prefer a strict tabular approach. Develop a technique in practice that feels comfortable – so by test day, you have a go-to system for puzzle questions.
🗝️ Using Venn Diagrams and Visual Aids for Logic
The Decision Making section frequently involves set logic and overlapping categories – classic scenarios for Venn diagrams. Many students find that sketching a quick Venn diagram (or interpreting a given one) can unlock complex logical relationships with ease. This is particularly true for syllogism questions or for questions that discuss groups and subsets.
Figure: Example of using a simple Venn diagram to visualise relationships in a syllogism question. In this illustration, all Taks are a subset of Quorks, which are in turn a subset of Fish, while Lumers are a separate subset of Fish. Visualising such relationships helps determine which conclusions can logically be drawn (e.g., “All Taks are Fish” would be true here, but “All Lumers are Quorks” would not).
If a question says, “All X are Y, and some Y are Z,” drawing two overlapping circles – one fully inside another – can help you see what’s definitely true or false. As a tip, use Venn diagrams to model syllogisms whenever the relationships get a bit confusing. By converting words into a picture, you avoid the mental jumble that complex statements can create. For example, consider: “All energy drinks contain caffeine. Company A’s drinks have taurine. All drinks to pass safety tests.” It can be tricky to mentally parse what follows from these sentences. But if you draw circles or boxes for each category (Energy drinks, Taurine, Passed tests, etc.) and mark the overlaps, the conclusions become much clearer. Even a rough sketch on your noteboard can give you the confidence to select the correct answer rather than guessing.
Likewise, understand how to read Venn diagram questions provided in the exam. Sometimes the question will show a Venn diagram with shaded areas or numbers and ask which conclusion is true. Make sure you know how set notation or shading works: for instance, if three circles overlap, a number written in an overlapping section belongs to all circles that overlap at that region. Practising a few Venn problems beforehand will build your intuition. The official advice is to brush up on basic probability and set theory for Decision Making – Venn diagrams fall right into that. It’s not advanced maths, just familiarity with the concepts.
Beyond Venn diagrams, use other visual aids where appropriate. For probability questions, drawing a quick probability tree or table can prevent mistakes, especially in multi-step probability calculations. If a problem involves spatial or shape-based logic (occasionally DM can have puzzles with shapes or pseudo-equations with symbols), don’t hesitate to rewrite them in algebraic form or sketch the shapes out. Turning a weird shape relationship into letters or variables (e.g., let ■ = 2, ▲ = 3, then ■ + ▲ = 5 type logic) can make it more straightforward. The bottom line is: translate the problem into a form that you find easiest to reason with – be it a diagram, a formula, or a sketch. The examiners won’t see your scratch work; they'll only see the answer you select, so use whatever helps you reach the correct answer as quickly as possible.
⏱️ Time Management and Tactics for DM Success
Time can be your biggest enemy in the UCAT, but the Decision Making section offers a slightly more generous pacing – just over a minute per question on average. Still, good time management is crucial. Here are some tactics to stay on track:
Aim for ~1 Minute per Question:
Since you have 35 questions in 37 minutes, on average, you can spend about 60–70 seconds on each. Some questions will naturally take less time – for example, a simple assumption or syllogism with only two short statements might be done in 20 seconds, which gives you extra time for the longer puzzles. An official tip is to practise the test timings and use the “flag and review” function for tougher questions. This means that if a question is taking too much time, you should flag it and move on rather than risk the entire section on one tricky problem.
Use a Two-Pass Strategy:
Many high scorers recommend a two-pass decision-making approach. In the first pass, answer all the questions that you find straightforward, or that can be solved relatively quickly. If a question seems very complex or you’re not making progress after 60-90 seconds, flag it and continue. Once you’ve gone through all the questions, you can return to any flagged ones with whatever time remains. This ensures you’ve at least seen and attempted every question (remember, unanswered questions definitely score 0, whereas a guessed question might just score a lucky point!). With this strategy, you won’t miss out on easy marks that were later in the section due to spending too long on a hard one early on.
Be Smart About Guessing:
There is absolutely no penalty for wrong answers in UCAT, so leaving a question blank is the worst thing you can do. If you’re running out of time and still have unanswered questions, make sure to provide an answer for each – even if it’s an educated guess. By eliminating a few options (as discussed earlier), you can often guess between the two remaining choices, giving you a 50/50 chance instead of 25%. If truly unsure, pick your favourite letter and move on. It’s also wise to budget a minute or two at the end (if possible) to quickly review flagged items or double-check any that you were uncertain about.
Keep an Eye on the Clock:
Develop a sense of timing. For instance, after ~18 minutes, you should be roughly halfway (around question 18 of 35). If you find you’re significantly behind, you might need to increase your pace or be more ruthless in skipping hard questions. Some candidates find it helpful to write a quick time checkpoint on their noteboard – e.g., “~18 Q by 19 min left” – so they know if they are on track. Others use the timing technique of splitting the section: one popular trick is to halve the questions and time (e.g., aim to have ~14 questions done in ~16 minutes, and ~7 questions done in ~8 minutes), as a rough guide. This can alert you if you’re falling behind schedule and help you adjust early, rather than panicking in the last 5 minutes.
Use Shortcuts and Tools:
In the UCAT computer interface, make use of any tools that can speed you up. For example, learn the keyboard shortcuts: Alt + N to move to the next question, Alt + P to go to the previous one, and Alt + F to flag/unflag a question. These can save you a few seconds of mouse fiddling on each question, which adds up over the whole test. When a question involves calculations or large numbers (like adding up values in a Venn diagram or computing a probability), don’t shy away from using the on-screen calculator. Some students prefer mental maths or writing it down, but the on-screen calculator can be quicker for certain tasks (just practice with it beforehand to get used to the keypad). You can even use it in simple cases like summing three or four numbers from a table, if that prevents errors. Remember, you can use the calculator’s memory functions to store interim results if needed.
Don’t Get Stuck in Perfectionism:
An important mindset tip: the goal is to get the right answer, not to fully “solve” every scenario to perfection. In a puzzle question, you might identify the correct answer choice without filling in every single detail of the scenario – that’s fine! For instance, if a puzzle asks “How many emails are between X and Y?” you don’t necessarily need to figure out the exact full order of all emails once you deduce the number is, say, 2. If, through logic, you conclude “there are two emails between them,” just select that and move on. It’s easy to waste time over-solving or double-checking an answer you’re already confident in. Trust your reasoning and keep momentum.
📈 Practise, Practise, Practise – and Track Your Progress
Finally, no amount of tips can replace the value of consistent practice. Decision-making is a skill, and, like any skill, you improve by doing. Work through plenty of practice questions of each type so that nothing in the real exam feels completely unfamiliar. The official UCAT Consortium recommends using the free official question banks and practice tests available on their website as the most accurate representation of the exam. These official materials will get you used to the style and difficulty of real UCAT questions. Of course, there are also many third-party resources and question banks; if you use them, be mindful to focus on quality and relevance (some unofficial questions might be either easier or harder than the real thing). Always circle back to official mocks as your exam approaches to calibrate your performance.
As you practise, identify your weak areas. Is it syllogisms that trip you up, or do Venn diagrams confuse you? Maybe you struggle with interpreting charts, or perhaps the logical puzzles eat up too much time. Once you know your weaker question type, you can put extra effort into it – targeted practice yields faster improvement than doing random questions without a strategy. For example, if probabilities are your Achilles’ heel, spend a day reviewing basic probability concepts and doing dozens of probability questions until you feel more comfortable. Meanwhile, maintain your stronger areas with occasional practice to keep them sharp.
It’s also very beneficial to keep a log of mistakes or difficult questions. After each practice session or mini-mock, jot down which questions you got wrong and why. Was it a misread keyword? A logical fallacy? A calculation error? By noting these, you’ll start to notice patterns. You might discover, for instance, that you often miss the word “not” in questions, or that you tend to assume the converse of statements in syllogisms. This self-awareness will help you adjust your approach and avoid repeating those mistakes. Some candidates even keep a “DM diary” to record the question types they struggled with and review it periodically. Over time, you should see those troublesome areas diminish as you address them head-on.
Lastly, simulate exam conditions for practice: use a timer, practise with the online format (including using the on-screen calculator and flagging tool), and work in a quiet environment. The more realistic your practice, the less intimidating the actual test will feel. And remember to practise decision-making questions under timed conditions regularly – this builds your speed and stamina.
🎉 Final Thoughts
Facing the UCAT Decision Making subtest may seem challenging, but with the right strategies, it can become a section where you excel. To recap, identify the question type promptly and apply the relevant approach, eliminate wrong answers to improve your odds, and stick strictly to the given information (no outside assumptions!). Use your logical toolkit – whether it’s Venn diagrams, sketches, or breaking down arguments – to untangle complex problems. Keep an eye on the clock, but don’t rush so much that you misread key details. And above all, practise these techniques beforehand so they become second nature.
Every year, thousands of sixth-formers conquer the UCAT – and you can be one of them. By following these DM top tips and putting them into practice, you’ll be able to approach decision-making questions with confidence and efficiency. Soon you’ll be picking up marks more quickly and pushing your UCAT score higher. Good luck, and happy practising – your future place at medical or dental school is within reach! 🚀
