How Is GAMSAT Section 2 Marked? The Real Criteria, Explained
8 min read · Updated 9 June 2026
Section 2 is the part of the GAMSAT candidates understand least, because ACER never hands back a marked script. You write two essays, you get a scaled score weeks later, and you are left guessing what moved the needle.
The marking is less mysterious than it feels. ACER assesses two broad qualities: the thinking, and the writing. Once you can see your own essay through those two lenses, you can mark it yourself, and fix the thing that is actually costing you.
The two things ACER is really judging
Official guidance comes down to two pillars: the quality and depth of what you say, and the control with which you say it. Everything else is a sub-part of one of those two.
It helps to break those two pillars into four working criteria you can actually score, each out of 25, summing to 100.
- Quality of thought: depth, originality, and genuine engagement with the theme's tension, not cliche.
- Global structure and argument: how the whole essay builds, paragraph to paragraph.
- Linguistic control: sentence-level precision, rhythm, grammar, and an authentic voice.
- Response to theme and task: answering the actual theme, reading the stimulus, sustaining a purpose.
Length and structure are not the score
A five-paragraph template does not earn marks. ACER explicitly rewards thinking, so a shorter essay with a sharper idea beats a longer one that pads a memorised structure.
Write to develop an idea, not to fill a shape. The structure should serve the argument, not the other way around.
Most first drafts sit in the 50s, and that is normal
On the scaled score, the bulk of first-draft essays land in the 50s. The 60s are competitive, and the high 60s and 70s are where strong applicants sit. Knowing this stops you over-reacting to a single essay and helps you read your own work honestly.
How to mark your own essay
Score each of the four criteria out of 25 and add them up. Be candid: a criterion is not a 20 because you tried hard, it is a 20 because a reader can see it on the page.
Then find the lowest of the four and fix only that in your next essay. One criterion at a time moves your score faster than vague rewriting.
The fastest way to see your essay clearly
The hard part is objectivity: you cannot easily see where your own argument drifts or where you asserted instead of argued. That is exactly what an external read gives you.
Our marker scores your essay on the four criteria out of 100, highlights the exact lines where the logic drifts or an idea goes unsupported, gives line-by-line edits, and rewrites a paragraph to the target standard, all in seconds. Create a free account and mark your first essays free.
