Across the exam(2)
Section I — Humanities(10)
Section I: find the argument
A repeatable method for the humanities section — locate the claim, the support, and the tone.
Inference vs assumption in Section I
Two question types people confuse — and the precise difference that gets you the mark.
Spotting logical fallacies
The reasoning flaws Section I loves to test — and how to name where an argument actually breaks.
Ethics & moral reasoning
The major ethical frameworks — so you can analyse any moral argument in Section I and II.
Identifying the conclusion
Find the one claim an argument is trying to get you to accept — and everything else falls into place.
Evaluating evidence
Does the evidence actually support the conclusion? The skill behind every strengthen/weaken question.
Tone & authorial intent
Read the author's attitude — admiring, skeptical, ironic — through word choice and what's left unsaid.
Reading & interpreting poetry
Read a poem closely — imagery, the speaker, form and shifts — instead of hunting for a hidden message.
Interpreting prose & fiction
Read fiction for character, perspective and subtext — what's shown, not just what's stated.
Social science reasoning
Arguments about people and society — and the correlation, confounding and competing-explanation traps they hinge on.
Section II — Written(4)
Writing a high-scoring Section II essay
Structure, development and the move that lifts an essay from competent to excellent.
Task B: the reflective essay
How to write a personal/reflective Section II essay that feels genuine, not generic.
Building persuasive examples
Specific, developed examples are the backbone of a strong Section II essay — one vivid example beats three vague ones.
Refining expression & style
Clear, controlled, varied prose is a third of your Section II score — and it's learnable.
Section III — Sciences(34)
Section III: reasoning, not recall
The single mindset shift that separates competitive Section III scores from the rest.
Reading graphs & data under pressure
A checklist for extracting the right information from figures fast — without the classic traps.
Equilibrium & Le Chatelier's principle
The high-yield chemistry idea behind a steady stream of Section III questions.
Acid–base & pH essentials
The acid-base reasoning that turns up again and again in Section III chemistry.
Genetics: inheritance & probability
Punnett-square reasoning and the probability skills behind Section III genetics.
Rates of reaction & kinetics
What changes a reaction's speed — and how Section III tests it with graphs and data.
Energy, work & power (physics essentials)
The handful of physics relationships that unlock a chunk of Section III.
Cell biology & membranes
The cell-membrane and transport ideas that drive a steady stream of Section III biology.
Organic chemistry: functional groups
Recognising functional groups — the pattern-matching that makes organic Section III tractable.
Enzymes & kinetics
How enzymes work, what Km and Vmax mean, and how to read inhibition graphs the GAMSAT way.
Stoichiometry & the mole
Moles, the n = m/M and n = cV shortcuts, mole ratios, and finding the limiting reagent.
Forces & Newton's laws
Free-body diagrams, F = ma, and the action–reaction trap — the core of GAMSAT mechanics.
DNA → RNA → protein
The central dogma, base pairing, codons and reading frames — enough to reason through any sequence question.
Redox & electrochemistry
Electrons changing hands — oxidation states, agents, and how a battery actually works.
Photosynthesis
How plants turn light into sugar — and where the oxygen you're breathing actually comes from.
The neuron & action potentials
How a neuron fires an all-or-nothing electrical spike — and the ion movements behind every phase.
Waves & sound
One equation, v = fλ, behind light, sound, ripples and earthquakes — plus the traps that trip people up.
Atomic structure & the periodic table
What's inside an atom, why isotopes exist, and how the table's shape predicts an element's behaviour.
Cellular respiration & ATP
How a single glucose is banked into ~30+ ATP across glycolysis, the Krebs cycle and the electron transport chain.
The kidney & the nephron
How the nephron filters ~180 L of blood a day and fine-tunes water and ions through filtration, reabsorption and secretion.
Hormones & the endocrine system
Chemical messengers, feedback loops, and the key idea: a hormone's mechanism depends on whether it can cross the cell membrane.
Homeostasis & feedback
How the body holds temperature, glucose and pH steady — the negative-feedback loop, and the rare positive-feedback exceptions.
Chemical bonding & intermolecular forces
Ionic, covalent and metallic bonds — and the weaker forces between molecules that set melting points and solubility.
Kinematics & motion
Describing motion with the SUVAT equations — and the projectile traps that catch people out.
Electricity & circuits
Voltage, current and resistance tied together by Ohm's law — and how series and parallel circuits differ.
Thermochemistry & enthalpy
Exothermic vs endothermic, the meaning of ΔH, and using bond energies and Hess's law.
Radioactivity & half-life
Alpha, beta and gamma decay, and the fixed-rate maths of half-life.
Organic reaction mechanisms
How electrons flow in organic reactions, and the SN1-vs-SN2 decision the GAMSAT loves.
Gas laws
The ideal gas law PV = nRT and the relationships behind it — with the Kelvin trap.
Natural selection & evolution
Why evolution is differential reproduction — not 'survival of the strongest' — and what selection actually acts on.
Ecology & populations
Energy flow, trophic levels and population growth — the relationships that structure every ecosystem.
Isomerism & stereochemistry
Same formula, different molecule — structural vs stereoisomers, chirality, and why it matters.
Momentum & collisions
Why momentum is conserved in every collision, and how elastic and inelastic collisions differ.
Light & optics
Reflection, refraction and Snell's law — why light bends and which way.
