UCAT · Get comfortable with the vocabulary.

Inference

A conclusion drawn from evidence in a passage even though it is not stated outright. You must judge whether the passage logically supports it.

Related: Assumption, Main idea, True/False/Cannot Say
Assumption

An unstated idea that a writer treats as true and that is needed for the argument to work. If it fails, the conclusion weakens.

Related: Inference, Logical validity
Main idea

The central point or overall message of a passage, rather than a supporting detail. It usually answers what the writer most wants you to understand.

Related: Inference, Tone
Tone

The writer's attitude towards the subject, shown through word choice and emphasis. It may be critical, neutral, enthusiastic, cautious or ironic.

Related: Main idea, Paraphrase
Paraphrase

A restatement of a passage's meaning in different words. It preserves the sense without copying the original phrasing.

Related: Main idea, Ambiguity
True/False/Cannot Say

A VR answer choice set where you decide if a statement follows, contradicts, or is not addressed by the passage, using only the text.

Related: Inference, Ambiguity
Skimming

Reading quickly to grasp structure and gist rather than every detail. It helps you locate sections worth reading more closely.

Related: Scanning, Main idea
Scanning

Searching a passage rapidly for specific words, numbers or names. You move your eyes selectively instead of reading every sentence.

Related: Skimming, True/False/Cannot Say
Ambiguity

A situation where words or sentences can be understood in more than one way. In VR, ambiguous wording can make an answer unsupported.

Related: Inference, Paraphrase
Syllogism

A form of reasoning with two or more premises that lead to a conclusion. You test whether the conclusion must follow, not just whether it seems plausible.

Related: Logical validity, Venn diagram
Necessary condition

A requirement that must be met for something to happen, though it may not be enough on its own. Without it, the outcome cannot occur.

Related: Sufficient condition, Logical validity
Sufficient condition

A condition that guarantees an outcome when it is met. Other conditions may also produce the same outcome, so it is not always the only route.

Related: Necessary condition, Logical validity
Logical validity

A property of an argument where the conclusion must be true if the premises are true. Validity is about structure, not factual accuracy.

Related: Syllogism, Necessary condition
Venn diagram

A diagram using overlapping circles to show how sets relate. It helps test whether a conclusion about categories is forced by the statements.

Related: Syllogism, Logical validity
Expected value

The average outcome of a gamble or choice if it were repeated many times, found by weighting each result by its probability.

Related: Probability, Pay-off table
Pay-off table

A grid showing the results of different choices under different possible situations. It helps compare options when outcomes are uncertain.

Related: Expected value, Cost-benefit analysis
Probability

A number from 0 to 1 expressing how likely an event is. It can be based on equally likely outcomes or observed frequencies.

Related: Expected value, Pay-off table
Cost-benefit analysis

A way to compare options by weighing their advantages against their disadvantages, often using money, time or points as a common measure.

Related: Pay-off table, Expected value
Percentage change

The difference between an old and new value, divided by the old value and multiplied by 100. It shows relative growth or decline.

Related: Ratio, Weighted average
Ratio

A comparison of two or more quantities showing how many times one contains another. Ratios can be scaled up or down while keeping the same relationship.

Related: Percentage change, Rate
Weighted average

An average where some values count more than others. You multiply each value by its weight, add the results, then divide by total weight.

Related: Median, Percentage change
Median

The middle value when a set of numbers is arranged in order. If there is an even number of values, it is the mean of the two middle ones.

Related: Weighted average, Estimation
Rate

A measure of how one quantity changes relative to another, such as cost per item or litres per minute. Units are essential when comparing rates.

Related: Ratio, Unit conversion
Unit conversion

Changing a measurement from one unit to another using a multiplier, such as minutes to hours or kilograms to grams.

Related: Rate, Estimation
Compound interest

Interest calculated on the original amount plus any interest already added. It grows faster than simple interest over time.

Related: Percentage change, Estimation
Estimation

Finding an approximate answer by rounding numbers to convenient values. It saves time and helps check whether a precise answer is reasonable.

Related: Median, Unit conversion
Correlation

A statistical relationship where two variables tend to change together. Correlation does not prove that one variable causes the other.

Related: Estimation, Weighted average
Appropriateness

How suitable a response is for the situation, considering professional standards and the feelings of those involved. It is judged separately from how important the action is.

Related: Importance, Professionalism
Importance

How significant an action or consideration is for resolving a situation safely and professionally. SJ questions often ask you to rate this separately from appropriateness.

Related: Appropriateness, Prioritisation

The duty to keep personal information private and share it only with those who need it for care or safety.
