UCAT Decision Making: turn a busy question into clear working

Start with the decision you must make

Is the question asking what must follow, what could happen, which argument addresses the issue or which option has the better probability? Those are different tasks. Read the instruction before spending time on a large diagram or table.

Medify recommends simple, organised working and attention to small qualifiers. Use the official tutorials to learn the conventions for each question type, including how the test uses logical terms. Do not replace those instructions with everyday assumptions.

Write facts differently from trial arrangements

Original Finesse example: Asha, Bilal and Chen give presentations. Asha speaks before Bilal; Chen is not first. Asha must be first: Bilal cannot be first because Asha precedes him, and Chen is excluded. Both Asha–Bilal–Chen and Asha–Chen–Bilal remain possible, so you cannot conclude that Bilal is second.

The important move is keeping both possibilities alive. If you sketch one legal arrangement and treat it as compulsory, a correct drawing can still produce the wrong answer. Label trial arrangements so you do not confuse them with stated facts.

Use the smallest useful representation

A few slots can handle an order problem; a compact table can track assignments; a simple set diagram can expose an overlap. Stop when the requested conclusion is established rather than decorating a complete solution you do not need.

For your next practice session, record the first unjustified step in each wrong solution. Was a possibility promoted to a certainty? Was a constraint dropped? Was an argument persuasive but irrelevant? Choose fresh questions that test that particular failure, then check whether your working prevents it.

• List the constraints actually supplied.
• Keep tentative placements visibly tentative.
• Try to disprove a ‘must’ claim with a valid counterexample.
• Return to the wording before submitting the answer.
