Biology (MDCAT & FSc)

Biology: The Highest-Yield Section in MDCAT

Biology is the single largest component of the PMC MDCAT (60 of 200 MCQs), the core of FSc Part-I and Part-II objective papers, and a fixture of the Everyday Science section in CSS/PMS General Science & Ability. It is also the section where marks are most recoverable: almost every question tests a named structure, a defined process, or a stated function rather than a calculation.

What the examiner actually tests

Cell biology: organelles and their functions, membrane transport (diffusion, osmosis, active transport), the cell cycle, mitosis versus meiosis, and chromosome behaviour.
Genetics: Mendelian ratios, testcross and backcross logic, linkage and crossing over, sex determination, mutations, and inheritance patterns in pedigree problems.
Human physiology: digestion and enzymes, circulatory and lymphatic systems, respiration and gas exchange, excretion (nephron mechanics), coordination, hormones and feedback loops.
Plant physiology: photosynthesis (light and dark reactions), respiration, transport in xylem and phloem, mineral deficiency, tropisms, and plant hormones.
Biomolecules & biochemistry: enzymes and their kinetics, carbohydrates, proteins, lipids, nucleic acids, and vitamins.
Ecology, evolution & classification: trophic levels, biogeochemical cycles, natural selection, homology and analogy, and the five-kingdom system.
Microbiology & immunity: bacterial and viral structure, pathogenesis, antibiotics, specific and non-specific defence, and vaccination.

How to use these sets

Every set holds up to 40 questions on one topic, and every answer carries an explanation that names the concept being tested and the distractor most candidates fall for. Work topic by topic rather than randomly: MDCAT biology repeats its framing year on year, so pattern recognition inside a single chapter pays off faster than breadth.

Revision checklist before the exam

Definitions straight from the PMC syllabus (homeostasis, tropism, allele, carrying capacity).
Numbers that are asked verbatim: normal blood pressure, dental formula, chromosome counts (human 46, dog 78, wheat 42), and vitamin deficiency names.
Exceptions — because MCQs are built on them: non-living examples, unusual cell organelles, and atypical inheritance.
