MDCAT MCQ Practice: Sample Questions With Answers
The following sample MCQs are structured around the most high-yield topics and reflect the style of questions that appear in MDCAT past papers.
Biology Sample MCQs
Q1. Which enzyme is responsible for unwinding the DNA double helix during replication?
(A) DNA polymerase I (B) RNA primase (C) Helicase โ (D) DNA ligase
Explanation: Helicase breaks the hydrogen bonds between base pairs to unwind the double helix. DNA polymerase adds new nucleotides, primase synthesises the RNA primer, and ligase joins Okazaki fragments.
Q2. Competitive inhibition of an enzyme can be overcome by:
(A) Increasing substrate concentration โ (B) Decreasing pH (C) Adding more enzyme (D) Increasing inhibitor concentration
Explanation: Competitive inhibitors compete with the substrate for the active site. Increasing substrate concentration outcompetes the inhibitor by occupying more active sites.
Q3. Which structure is responsible for ATP synthesis in the mitochondrion?
(A) Inner membrane matrix (B) Outer mitochondrial membrane (C) ATP synthase (Complex V) on the inner membrane โ (D) Cristae lumen
Explanation: ATP synthase (Complex V) uses the proton gradient across the inner mitochondrial membrane to synthesise ATP through oxidative phosphorylation.
Q4. In humans, which blood type is the universal donor?
(A) AB+ (B) Aโ (C) Oโ โ (D) O+
Explanation: Oโ blood has no A, B, or Rh antigens on its red blood cells, making it safe to transfuse to recipients of any blood type.
Q5. The number of chromosomes in a secondary oocyte at the time of ovulation is:
(A) 46 (diploid) (B) 23 pairs (C) 23 (haploid) โ (D) 46 pairs
Explanation: After Meiosis I, the secondary oocyte has 23 chromosomes (haploid). Meiosis II completes only after fertilisation.
Chemistry Sample MCQs
Q6. Which of the following increases when temperature is raised for an exothermic reaction at equilibrium?
(A) Equilibrium constant (Kc) (B) Rate of reverse reaction โ (C) Concentration of products (D) Value of ฮH
Explanation: Le Chatelier’s Principle โ raising temperature for an exothermic reaction shifts equilibrium left (toward reactants), increasing the reverse reaction rate. Kc decreases for exothermic reactions with increased temperature.
Q7. The hybridization of carbon in ethyne (CโHโ) is:
(A) spยณ (B) spยฒ (C) sp โ (D) spยณd
Explanation: Each carbon in ethyne forms a triple bond โ one sigma and two pi bonds. This requires sp hybridisation, leaving two unhybridised p orbitals for the pi bonds.
Q8. Which of the following is a secondary alcohol?
(A) CHโOH (B) CHโCHโOH (C) CHโCH(OH)CHโ โ (D) (CHโ)โCOH
Explanation: A secondary alcohol has the OH group attached to a carbon bonded to two other carbon atoms. CHโCH(OH)CHโ (isopropanol) fits this definition.
Physics Sample MCQs
Q9. An object is thrown horizontally from a height. Which quantity remains constant during projectile motion (ignoring air resistance)?
(A) Vertical velocity (B) Total velocity (C) Horizontal velocity โ (D) Vertical acceleration changes with height
Explanation: In projectile motion, horizontal velocity is constant because no horizontal force acts on the object. Only vertical velocity changes due to gravitational acceleration.
Q10. The photoelectric effect proves that light has:
(A) Wave nature only (B) Particle and wave nature simultaneously (C) Particle nature โ (D) Neither wave nor particle nature
Explanation: The photoelectric effect โ where electrons are ejected from metal surfaces by light โ could not be explained by wave theory. Einstein explained it by treating light as photons (particles), proving its particle nature.
English Sample MCQs
Q11. Choose the correct synonym of “BENEVOLENT”:
(A) Malicious (B) Indifferent (C) Charitable โ (D) Hostile
Q12. Identify the correctly punctuated sentence:
(A) However she tried she couldn’t solve the problem (B) However, she tried, she couldn’t solve the problem (C) However hard she tried, she couldn’t solve the problem โ (D) However hard, she tried she couldn’t solve the problem

How to Practice MDCAT MCQs Effectively
Doing MCQs is not the same as doing MCQs correctly. These two practices look similar on the outside โ both involve answering questions โ but they produce vastly different results.
The Wrong Way
- Attempting MCQs and immediately checking answers
- Moving on after getting an answer wrong without understanding why
- Focusing only on getting through questions rather than absorbing why specific options are right or wrong
- Attempting MCQs when tired or distracted
The Right Way
Step 1: Chapter first, MCQs second Always complete a chapter before attempting MCQs from it. The goal of MCQ practice is application and retention testing โ not first exposure to a concept.
Step 2: Attempt MCQs before checking answers Attempt every question fully before looking at the answer key. The cognitive effort of thinking through each option โ even when you’re uncertain โ builds the neural pathways that retrieval practice requires.
Step 3: Analyse every wrong answer, not just the total score For every incorrect answer, understand:
- What was the correct concept?
- Why was your chosen option wrong?
- Why is the correct option right?
- Which part of the chapter does this question test?
Step 4: Re-test after 48 hours After studying the correct answers to your wrong questions, return to those specific MCQs 48 hours later without looking at your previous answers. If you still get them wrong, the concept needs more focused revision.
Step 5: Chapter-wise โ Mixed โ Full Mock Follow this progression: chapter-wise MCQs โ mixed subject MCQs โ full 180-question timed mock tests. Each stage builds toward exam-day performance.

Are MDCAT MCQs from FSc textbooks? (cite index=”13-1″>The MDCAT 2026 syllabus is based on FSc pre-medical textbooks from Punjab Textbook Board and federal boards.</cite> However, the MCQ style goes beyond textbook definitions โ questions test application, conceptual understanding, and the ability to eliminate incorrect options, not just recall.
Conclusion: MCQ Mastery Is the Difference in MDCAT 2026
The MDCAT is 180 MCQs. Every mark in the exam comes from selecting the correct option in a question with four alternatives. There is no extended writing, no diagrams to draw, no calculations to present. Just MCQs โ 180 of them, in 3 hours, on a single September day.
The candidate who practises the right MCQs, from the right topics, with proper error analysis and timed mock conditions, arrives at that day in a fundamentally different position from the candidate who revised notes and hoped for the best.
(cite index=”14-1″>Practising MDCAT past papers and MCQs is the most effective preparation strategy because you understand the exact exam pattern and question style, and identify your weak subjects before the real test.</cite)
Start with Biology โ it’s 45% of your paper and mastering high-yield topics like enzymes, DNA replication, and bioenergetics alone can secure 30+ marks. Build Chemistry next. Physics follows. English and Logical Reasoning are scored with targeted daily practice of 20โ30 minutes.
The MDCAT 2026 date is 20 September 2026. The preparation window is finite. Start today.
