UCAT Decision Making question types and methods

UCAT Decision Making tests logic, arguments and statistical reasoning. Some items ask for one option; others ask you to mark five statements Yes or No. Start by identifying the reasoning task before choosing a method. The official format and question tutorials are linked below.

Use a method suited to the evidence

The following is our practice map, not a promised distribution of question types in a live test. Use the current official DM tutorial to see its presentation.

Practice familyA useful first moveA trap to check
Syllogisms and deductionsTranslate each condition without reversing itAll A are B does not mean all B are A
Logical puzzlesWrite fixed constraints before testing optionsA possible arrangement is not a necessary one
Interpreting informationCheck each statement against the given evidenceUsing outside knowledge
Arguments and assumptionsMatch the reason to the precise questionA true claim that is irrelevant
Venn diagrams and setsSeparate overlaps from totalsCounting the overlap twice
ProbabilityDefine the event and the denominatorAssuming independence without justification

Judge each statement independently

Worked example A fictional training group

Original teaching example. Exactly 30 trainees attend at least one of two workshops: coding or statistics. Twenty attend coding and 18 attend statistics. No other workshops count. Mark Yes if the conclusion follows, otherwise No: (1) Eight attend both. (2) Twelve attend coding only. (3) Ten attend statistics only. (4) Every statistics attendee attends coding. (5) More attend coding only than statistics only.

Why this works: Yes, Yes, Yes, No, Yes. The overlap is 20 + 18 − 30 = 8. Coding only is 20 − 8 = 12; statistics only is 18 − 8 = 10. Those three regions sum to 30. Statement 4 fails because ten attend statistics without coding.

Why the tempting route fails: Treating 20 + 18 = 38 as the number of people counts eight people twice. Each statement needs its own check; the first answer does not determine the remaining four.

Review at statement level

Our suggestion: keep an error log by reasoning family. For a multi-statement item, record the particular statement and assumption that caused the miss. Do not infer an official scaled score from the number of questions you got right.
