The short answer
The single mindset shift that separates competitive Section III scores from the rest.
Written and checked by GAMSAT tutors — not AI-generated.
Try the reasoning style
We treat forgetting as a failure — a lapse to be patched with reminders and records. Yet a mind that kept everything could not think; it would drown in the undifferentiated noise of every moment it had ever lived. To forget is not so much to lose information as to decide, mostly without our noticing, what was never worth keeping.
The author's argument relies most directly on which unstated assumption?
Pick an option to see how the tutor reasons to the answer — not just whether you were right.
Not quite — the answer is B.
Work backwards from the conclusion: a mind that ‘kept everything’ supposedly ‘could not think.’ That only follows if thinking means leaving most of experience out — so B is the premise the argument quietly rests on. A raises reliability, which the passage never weighs; C contradicts ‘mostly without our noticing’; D smuggles in a claim about intellect the passage never makes. The question rewards finding the hidden premise, not recalling a fact.
Most people prepare for Section III like a university exam — memorising facts and formulas. That is the wrong model, and it quietly caps your score. The science is only the context; the thing actually being tested is your reasoning.
Two ways to prepare
Memorising (caps your score)
- Cramming facts, reactions and formulas
- Panicking at unfamiliar content
- Hunting for the 'remembered' answer
- Relying on outside knowledge
Reasoning (what's rewarded)
- Know the core, then interpret
- Stay calm — new content is the point
- Work the answer from the stimulus
- Treat each stimulus as self-contained
If a question can be answered by recalling a fact, it is probably not a real GAMSAT question.
A reliable approach to every question
Read the question stem first
Know what you are hunting for before you wade into the stimulus.
Locate the specific part
Find the exact graph, line or value the question points to. Don't re-read everything.
Name the principle
Ask: what relationship is being tested — a trend, a trade-off, cause and effect?
Eliminate by error type
Cut options that misread the data, reverse a relationship, or are true-but-irrelevant.
Reasoning in action
A graph shows enzyme activity rising with temperature to a peak at 40 °C, then falling sharply. A question asks why activity drops after 40 °C — and you have never seen this enzyme. How do you answer?
Check yourself
A question gives you an unfamiliar reaction scheme and asks which step is rate-limiting. You have never seen the reaction. The best first move is to:
Key takeaways
- Section III tests reasoning; the science is just the context.
- Every answer is supported by the stimulus in front of you.
- Read the stem first, locate the evidence, name the principle, eliminate by error type.
- Unfamiliar content is deliberate — stay calm and work from first principles.
