What Decision Making tests — and why it matters more in 2026
Decision Making (DM) assesses how well you reason through problems using logic, statistics and probability — not how much you already know. Every question is self-contained: the information you need is on the screen, and importing outside assumptions is exactly how careful candidates still lose marks.
Two changes make DM more important for 2026. With Abstract Reasoning removed, the UCAT now has three cognitive sections — Verbal Reasoning, Decision Making and Quantitative Reasoning — plus the Situational Judgement Test, with a total scored out of 2700. And DM has been expanded to 35 questions in 37 minutes, so there are more marks on offer here than in previous cycles. Each cognitive section is scaled from 300 to 900, which means a strong DM performance can visibly lift your overall total.
Because DM is learnable through method rather than memorisation, it is often the section where focused candidates gain the most ground. The rest of this guide shows you where those gains come from.
The six Decision Making question types
DM draws on six recurring formats, and recognising which one you are looking at — then choosing the fastest route through it — is half the battle.
Syllogisms: you are given statements and asked which conclusions logically follow. Test each conclusion on its own and accept only what must be true, never what merely could be true.
Logic puzzles: deduce an arrangement from a set of clues. Sketch a quick grid or ordering on the whiteboard — a clue like 'the brick house comes after the wooden house' already tells you the wooden house cannot be last and the brick house cannot be first.
Interpreting information: read data, text or a chart and judge what it genuinely supports. Anchor each answer to the source rather than to what feels plausible.
Recognising assumptions and evaluating arguments: decide whether an argument is strong or weak. A strong argument is both relevant and directly answers the question being asked.
Probabilistic reasoning: work with simple probabilities and expected outcomes. Drill fractions, percentages and the 'and / or' rules until they are automatic.
Venn diagrams: place values into overlapping sets. Practising quick two- and three-set diagrams turns these into reliable, fast marks.
“Decision Making rewards method over memory. The candidates who improve fastest aren't smarter — they have a repeatable process for each question type, and they trust it under the clock.”
Timing, the on-screen tools, and when to move on
Thirty-five questions in 37 minutes is roughly 63 seconds each — but DM questions vary enormously in length, so a uniform pace is the wrong target. The aim is to finish the short questions quickly and bank that time for the heavier logic puzzles.
Three habits protect your score. First, flag and move: if a question is clearly going to cost two minutes, flag it, commit to your best answer, and return only if time allows — one stubborn puzzle can quietly cost you three easier marks elsewhere. Second, use the tools deliberately: DM gives you an on-screen calculator and a whiteboard, so practise with both until navigating them is automatic and you are not losing the very seconds you are trying to save. Third, never leave a blank: there is no negative marking, so with about a minute left, put an answer on every question still open.
A four-step method that turns practice into score gains
Volume alone does not raise your DM score — structured review does. This loop is what consistently works.
First, diagnose: take a timed set and record your accuracy by question type. Most candidates are strong on one or two formats and lose marks on the same one or two every time. Second, drill the weak type in isolation, untimed at first so you groove the correct reasoning, then gradually reintroduce time pressure. Third, review every mistake properly: for each wrong answer, write the single reason it was wrong — misread the stem, imported an assumption, rushed the arithmetic — and the patterns become obvious quickly. Fourth, re-test under timed, mixed conditions to confirm the fix holds when question types are shuffled and the clock is running.
If you are not sure which question type is costing you marks, the fastest way to find out is a timed diagnostic. You can take a free MediSpoon diagnostic to see your Decision Making performance broken down by type and benchmarked against other applicants, so your preparation targets the right weakness from day one.
