MDCAT Logical Reasoning: Question Types and How to Solve Them

MDCAT Logical Reasoning is a section of 9 MCQs worth 5% of the 180-mark test. It was first added to the national MDCAT by PMC in 2021 and carried into the current PMDC 2025/2026 curriculum, and a lot of students still skip it in practice. The good news: it tests thinking, not memory. There is nothing to mug. Once you know the 6 question types and a clean method for each, these 9 marks become some of the easiest on the paper.

This guide breaks down every official Logical Reasoning question type, shows how to approach each one, and gives you a simple way to practise so you do not lose marks you should be getting.

What is in the MDCAT Logical Reasoning section?

The MDCAT Logical Reasoning section is 9 MCQs (5% of 180) and, per the official PMDC 2025 curriculum, covers six areas: critical thinking, letters and symbol series, logical deductions, logical problems, course of action, and cause and effect. Each question gives you a short passage or statement and asks you to pick the most logical answer. There is no negative marking, so never leave a Logical Reasoning question blank.

The section sits alongside English (also 9 MCQs). The full MDCAT 2025/2026 paper is Biology 81, Chemistry 45, Physics 36, English 9, and Logical Reasoning 9. So while Logical Reasoning is small, every mark counts when merit lists are tight.

What are the MDCAT Logical Reasoning question types?

There are six official question types in MDCAT Logical Reasoning. Each one has a fixed method. Learn the method, and you stop guessing. Here is each type with the approach that works fastest under exam pressure.

Critical thinking

Critical thinking questions give you an argument and ask whether the conclusion holds. The trick is to split what is stated from what is assumed. Treat the passage as true, then check if the answer must follow from it. If an option needs a fact that was never given, it is wrong, even if it sounds reasonable in real life.

Letters and symbol series

These give a sequence and ask for the missing or next term, for example: SCD, TEF, UGH, ____, WKL. The fastest method is to number the letters by their alphabet position and look at the jump between each group. Here the first letters go S, T, U, then V. Once you find the pattern in each position, the answer falls out. Number the letters, do not eyeball them.

Logical deductions

You read a short passage and choose which statement is most accurately deduced from it. Only use what is on the page. The wrong options are usually true-sounding statements that the passage never actually supports. If you have to add your own knowledge to make an option correct, eliminate it.

Logical problems

These are puzzles: who sits where, who ranks higher, which item matches which person. Do not try to hold it all in your head. Draw a tiny grid or a line on your rough sheet, lock in the clues that are certain, then cross out what cannot be true. The answer is whatever is left.

Course of action

You get a problem and two or more suggested actions, and you decide which actions logically follow. Pick actions that are realistic and directly address the problem. Reject anything too extreme, too vague, or unrelated. A good course of action is something a sensible person would actually do about that specific problem.

Cause and effect

You are given two events and asked how they relate: is one the cause, the other the effect, or are they independent? Ask whether the first event clearly makes the second happen. Watch the common trap where both events are really effects of a third, hidden cause, which means neither caused the other.

How do you solve MDCAT logical reasoning questions under time pressure?

The fastest way to solve MDCAT Logical Reasoning is to identify the question type first, then apply its fixed method instead of reasoning from scratch. With 9 questions, you should aim to spend under a minute each and not get stuck. Follow this order.

1. Read the question and name the type (series, deduction, course of action, and so on).
2. Apply that type's method: number the letters, build a grid, or split facts from assumptions.
3. Eliminate options that need information not given in the passage.
4. If two options remain, pick the one that follows strictly from the text, not the one that feels true.
5. Stuck after 60 seconds? Mark your best guess and move on. No negative marking means a blank is a wasted mark.

How should you practise MDCAT logical reasoning?

Practise by type, not at random. Do a batch of letter-series questions until the pattern-spotting is automatic, then move to deductions, then course of action, and so on. Logical reasoning is a skill that gets faster with reps, so 15 minutes a day for a few weeks beats one long session. Time yourself, because speed is half the battle in this section.

Use real MCQs and check the explanation for every one you get wrong, so you learn the trap, not just the answer. You can practise MDCAT and ECAT MCQs on Parhlai by topic, see worked explanations, and track which logical reasoning types you keep missing. That feedback loop is what turns a weak section into 9 secure marks.

Logical reasoning rewards method over memory. Name the type, apply the rule, and these 9 marks become the most predictable on the paper.

Is MDCAT logical reasoning hard?

MDCAT Logical Reasoning is not hard once you know the question types, but it catches students who never practise it because it is new and there is nothing to memorise. Most questions are solvable with a calm, step-by-step method. The students who lose marks are the ones who rush, skip the method, or run out of time. Treat it like a skill you build, and 7 to 9 out of 9 is realistic for most students.
