GAMSAT Section 3 practice questions in the modern style

The exam moved. Old-style practice papers test recall; the modern Section III hands you an unfamiliar experiment, graph or mechanism and tests whether you can reason from it — 75 questions, 150 minutes, 2 minutes each, double-weighted in your overall score.

Three sciences, one skill

Biology

Enzymes, transport, genetics, ecology — served as experiments to interpret, not lists to remember. Topic list

Chemistry

Equilibrium, acids and bases, dilution, kinetics — the arithmetic is simple; the setup is the test. Topic list

Physics

Waves, forces, energy — no calculator, so estimation is the skill. Formula sheet · Topics

Written in-house for demonstration — the free test deals real bank questions like it.

A 12 mM stock solution is diluted 1 in 4, and the result is then diluted 1 in 3.

The final concentration is…

A  1 mM — each dilution divides: 12 ÷ 4 = 3, then 3 ÷ 3 = 1 mM. Serial dilutions compound — multiply the factors first (4 × 3 = 12), then divide once.
B  4 mM — stops after the first dilution; the 1-in-3 step never happens.
C  1.7 mM — divides by 7 — dilution factors multiply, they never add.
D  9 mM — subtracts 3 from 12; a 1-in-3 dilution divides by 3, it doesn’t remove 3 mM.

Ninety seconds of work — if you set it up right. That setup-under-time is the whole section, and it is what the free test’s pace bar trains.

Section 3 practice, answered

How many questions are in GAMSAT Section 3, and how long is it?

75 multiple-choice questions in 150 minutes — exactly 2 minutes per question. It is double-weighted in the overall score, and sat in person on the same day as Section I, about three weeks after the remote Section II writing day.

Is Section 3 a science knowledge test?

Less than it used to be. The modern exam leans hard toward reasoning: most questions give you the data, graph or mechanism you need and test whether you can work with it under time. A grounding of roughly first-year-university biology and chemistry and senior-secondary physics is assumed, but recall alone answers very few questions.

Where can I get free GAMSAT Section 3 practice questions?

The free 12-question practice test on this site deals three Section III science sets daily — chemistry, biology and physics — at the real 2-minute pace, each with worked reasoning. ACER's official booklets remain the only official questions; do those first.

How do I practise the 2-minute pace?

Answer against a visible clock from day one. The free test shows a live pace bar against the real per-question budget, and the full timed mode in the free app tracks your pace on every question you attempt.
