Most Repeated MDCAT Logical Reasoning MCQs — Series and Deduction

Logical Reasoning is not in the old UHS book. It has been in every national MDCAT since 2020. Forty-five questions cover the patterns the paper actually repeats: series, syllogism, direction, coding, course of action.

What MDCAT Logical Reasoning repeats

Letter and symbol series is the largest chapter (23 questions): n(n+1), primes, squares, +2 letters, reverse alphabet. Deduction is conversion and the forbidden extra overlap — all A are B does not force some A are C. Direction and blood relations are net displacement and generation counts, not story problems.

Times is 2020–2025. Early UHS papers do not contain this section.

How to practise LR without overthinking

  1. Series first. Write the step on paper before you look at options.
  2. Deduction: only convert what the statement allows. All A are B → some B are A (exam convention). Not some A are C.
  3. Course of action: practical, not extreme. Education problems get education answers.
