If you're preparing for the GAMSAT ® with a non-science background, you're probably wondering how much science you actually need, how long preparation will take, and whether you're at a serious disadvantage compared to science graduates. The short answer: you can absolutely sit the GAMSAT ® without a science degree, and many non-science students achieve competitive scores every year.
This guide covers everything a non-science student needs to know — from the science knowledge required, to realistic preparation timelines, to how your humanities strengths can work in your favour across all three sections of the GAMSAT ®.
Yes — and ACER, the organisation that develops the GAMSAT ®, explicitly encourages it. Their information booklet states that candidates whose first degree is in a non-scientific field of study can still sit the GAMSAT ® and succeed in an application for admission to one of the graduate-entry programs, and that institutions encourage applications from candidates who have achieved academic excellence in the humanities and social sciences.
The GAMSAT ® is designed to assess reasoning and critical thinking rather than knowledge recall. Section 3 does require foundational science knowledge, but the exam presents novel scenarios and asks you to interpret data and form conclusions — skills that aren't exclusive to science graduates. Many students from arts, law, commerce, and humanities degrees receive excellent marks across all three sections.
It's also worth remembering that the sciences in the GAMSAT ® can be quite "pure" (e.g. pure chemistry or theoretical physics), so even students with biomedical science degrees may find their coursework doesn't cover everything. The playing field is more level than it first appears.
The real factor that determines success is preparation time. Students from non-science backgrounds need to allow extra months to build foundational science knowledge, but once that groundwork is in place, the exam tests the same reasoning skills for everyone. The key is starting your preparation early and approaching it with a structured plan.
Non-science students face a genuine challenge in Section 3, but the difficulty is often overstated. The GAMSAT ® consists of three sections:
Here's what non-science students often overlook: you likely have a genuine advantage in Sections 1 and 2. These sections reward exactly the skills that arts, law, and humanities degrees develop — critical reading, textual analysis, and persuasive writing. Research analysing ten years of GAMSAT ® candidate data found that law students in particular score very highly in Sections 1 and 2, and that the overall score gap between humanities and science graduates is modest — roughly three points on average.
The most common reason non-science students struggle is not understanding what the GAMSAT ® is actually testing. Because it is primarily a reasoning examination rather than a recall exam, most of the information you need to answer each question is provided in the stimulus. The additional challenge is the time pressure of reasoning with unfamiliar concepts — but this is something all students face, regardless of background.
The hardest part for most non-science students is the time investment. Learning science from scratch takes months, and the unfamiliar terminology can feel overwhelming at first. But the exam doesn't reward rote memorisation — it rewards the ability to reason through novel problems with a solid knowledge base. That's a learnable skill.
Getting into medical school without a science degree is not only possible — it's explicitly welcomed by the admissions process. GEMSAS (the Graduate Entry Medical School Admissions System) states that applicants need a three-year bachelor degree in any discipline. The system does not preference graduates with particular bachelor degrees.
Almost all Australian graduate-entry medical schools have removed science subject prerequisites. One exception is the University of Queensland, which requires completion of two specific prerequisite courses — Systems Physiology (BIOM2012) and Integrative Cell and Tissue Biology (BIOM2011) — within 10 years of commencing the program. Equivalent courses from other institutions may be accepted. Monash University also requires a prior relevant science-based undergraduate degree at Monash University.
Students from non-science backgrounds often perform just as well as — or even outperform — their science-background peers once enrolled in medical school. Non-science graduates tend to bring different but equally valuable skills, including stronger communication, adaptability, and emotional intelligence. If you experience imposter syndrome during the application process, remember that medical schools actively seek students from diverse academic backgrounds precisely because diverse thinking contributes to better clinical outcomes.
For all other graduate-entry medical schools, a student with a Bachelor of Arts receives the same consideration as a student with a Bachelor of Science, and once enrolled, the same medical training and qualification. If you want to explore how different schools assess applicants, our guide to medical school entry requirements covers GPA thresholds, GAMSAT ® minimums, and interview processes in detail.
Some pathways to medicine in Australia are specifically designed for career changers and graduates from diverse backgrounds, so a non-science degree is by no means a barrier.
ACER recommends that GAMSAT ® candidates have science knowledge equivalent to first-year university Biology and Chemistry, and Year 12 (HSC/VCE) equivalent Physics.
For a non-science student, that description can feel abstract. In practical terms, "first-year university level" means understanding core principles well enough to apply them — not memorising textbook detail. For example, in biology you should understand how DNA replication works at a conceptual level, but you don't need to memorise every enzyme in the pathway. In chemistry, you should understand what happens when you add an acid to a solution and why, not the name of every organic functional group.
Most Section 3 questions present new information and novel scenarios that would be unfamiliar even to undergraduate science students. A solid foundation in the sciences allows you to filter out unnecessary information and interpret data more quickly — and since many students don't finish Section 3, that speed matters.
For a complete list of topics, our GAMSAT ® Study Syllabus covers Sections 1, 2, and 3 in detail.
Section 3 of the GAMSAT ® draws roughly 40% of its questions from biology, 40% from chemistry, and 20% from physics. Here's what each discipline involves at the level you need:
| Discipline | Required Level | What It Covers | Study Time (from scratch) |
|---|---|---|---|
| Biology | First-year university | Cell biology, genetics, human physiology, evolution, organ systems | 7–8 weeks |
| Chemistry | First-year university | Atomic structure, bonding, organic chemistry basics, acids and bases, thermodynamics, equilibrium | 7–8 weeks |
| Physics | Year 12 equivalent | Mechanics, electricity, waves, optics, thermodynamics, basic nuclear physics | 3–5 weeks |
These timelines assume focused study of around 15 hours a week - which is doable but very substantial for the typical student and especially for the full time worker. Unless you know you can consistently put in quality hours, we recommend that you double the above timelines. If you have some familiarity with basic science concepts from high school — for example, if you studied biology or chemistry until Year 11 — these timeframes may be shorter. Prior exposure to scientific thinking, even at a basic level, can significantly improve the speed at which you build more advanced understanding.
The biology and chemistry will take the most time because their scope is broader; physics is narrower but its unfamiliar format can require extra practice. You can find subject-specific preparation strategies on our dedicated Biology, Chemistry, and Physics pages, and a complete topic checklist in the GAMSAT ® Study Syllabus.
Physics makes up only 20% of Section 3 of the GAMSAT ®, and many non-science students assume they can simply skip those questions and absorb the lost marks. This is a mistake — and here's why.
First, because few students have strong physics backgrounds, correct answers on physics questions can carry disproportionate weight. The GAMSAT ® uses Item Response Theory scoring, meaning questions answered correctly by fewer candidates may contribute more to your scaled score. Physics questions often fall into this category, making them a genuine differentiator.
Second, ACER increasingly combines elements of physics and mathematics within both Biology and Chemistry questions. In practice, this means that 40–50% of Section 3 questions may require some level of maths or physics reasoning — basic arithmetic, manipulating formulae, interpreting graphs — even when the question stem is predominantly biological or chemical in nature.
It's also worth noting that Section 3 questions frequently combine concepts from multiple disciplines into a single question — so the sciences are not always isolated from one another. A question may present a biological scenario that requires physics reasoning to solve, or a chemistry problem that draws on mathematical skills.
A classic example: a question stem reviews the flow of blood through a major artery. What happens if the blood pressure increases — would the diameter of the blood vessel decrease or increase? This kind of question appears not only in the GAMSAT ® but in medical school itself. It requires understanding the physics of fluid dynamics (pressure, flow rate, vessel compliance), combined with biological knowledge of how blood vessels respond to pressure changes.
The fear of physics is understandable but often irrational. The format may be unfamiliar — there will be an emphasis on formulas, equations, and graphs — but after reading through the stem and reasoning through the ideas, you'll often find the logic is the same as in other disciplines. Instead of reasoning with words, you're reasoning with formulas. Our dedicated guide on GAMSAT ® Physics: How to Prepare covers the key topics and strategies in depth.
Maths anxiety is common among non-science students preparing for the GAMSAT ®, and it's worth addressing directly: the maths required for Section 3 is more basic than most people expect.
Calculators are not permitted in the GAMSAT ® — they were removed over a decade ago. The exam is designed so that necessary values (scientific constants, logarithms, trigonometric values) are provided in the question stimulus. You're not expected to perform complex calculations from memory.
The core maths skills you need include basic arithmetic (multiplication, division, working with fractions), estimation and approximation, interpreting graphs and tables, basic algebra (rearranging equations), scientific notation, and an understanding of logarithms for acid-base and pH questions. Precision isn't the goal — the exam tests mathematical skill and estimation, not calculator-level accuracy.
If you studied any quantitative subject at university — economics, statistics, psychology research methods, even accounting — you likely have stronger maths foundations than you realise. For those starting from scratch, a few weeks of focused practice with estimation, unit conversion, and graph interpretation will cover most of what's needed. For a full breakdown of the maths topics tested, see our GAMSAT ® Section 3 preparation guide.
This is one of the first questions every non-science student asks. Based on preparation provider recommendations and student outcomes, non-science students should allow a minimum of four months for thorough GAMSAT ® preparation. Students with very limited science exposure — for example, those who haven't studied any science since high school — should consider allowing six or more months.
For context, students with a science background typically prepare for three to four months. The additional time for non-science students goes primarily toward building foundational science knowledge before progressing to exam-style practice.
A realistic weekly commitment is 10–15 hours, which is achievable alongside full-time work or study. If you're aiming for the March or September GAMSAT ® sitting, count backwards from the exam date to determine when you need to start.
A phased approach works best. Here's a suggested breakdown:
Phase 1 — Build Science Foundations (Months 1–2)
Dedicate most of your study time to learning core science concepts across biology, chemistry, and physics. Use the GAMSAT ® Study Syllabus as your topic checklist. Focus on understanding principles rather than memorising detail. Start with whichever discipline feels most accessible — biology is often a natural starting point because the concepts connect to everyday health and body knowledge.
Phase 2 — Integrate Practice Questions (Months 2–3)
Begin working through GAMSAT ® practice questions alongside your content learning. Use questions diagnostically to identify gaps in your knowledge. The goal is to see how concepts are applied in exam conditions, not to achieve perfect scores immediately. Review every wrong answer carefully.
Phase 3 — Exam Readiness (Months 3–4+)
Shift the majority of your time to full-length GAMSAT ® practice tests under timed conditions. Focus on time management, question prioritisation, and refining your approach to unfamiliar question stems. Use your results to target any remaining weak areas.
For a detailed week-by-week plan, our GAMSAT ® Study Schedule provides a customisable framework.
Before you can plan your preparation, you need to know where you stand. The best starting point is a diagnostic test — attempting a set of practice questions before you begin studying gives you a concrete sense of what the exam questions look like and establishes a benchmark for where you currently stand. From there, you can build your foundational science knowledge with a targeted focus on your areas of weakness.
Here's a practical self-assessment process:
With a clear sense of the science requirements and a realistic timeline, the next step is building an actual preparation strategy. The tips below are structured as a logical progression — not a disconnected list of advice.
Start early. With a non-science background, you need extra time compared to science graduates, and front-loading the foundational science learning is critical. The goal is to understand core principles — not to memorise undergraduate textbooks.
Create a study plan using the GAMSAT ® Study Syllabus as your guide. Work through the topic list systematically, focusing on why things work rather than what to memorise. For example, understanding why acids donate protons (and what that means for biological systems) is more valuable than memorising the names of twenty amino acids.
Track your progress as you go — noting which topics are solid, which need revision, and which you've skipped to come back to. You can find free preparation materials on our website, including our Section 3 guide and the individual guides for Biology, Chemistry, and Physics.
Once you have a reasonable grasp of the foundational science, shift the bulk of your preparation toward working through GAMSAT ® practice questions. This should ultimately form the largest portion of your study time.
You don't need to finish all your content learning before starting questions — in fact, interleaving questions with content study is more effective. As you work through questions, note concepts you struggle with and return to the foundational material to fill those gaps. This feedback loop between questions and content is where the real learning happens.
The critical habit is reviewing wrong answers thoroughly. Don't just check the correct option — understand why each wrong option is wrong and what reasoning you missed. This builds the analytical skills the GAMSAT ® is actually testing.
Our GAMSAT ® MCQ Bank offers 20 free questions as part of the free trial, covering all Section 3 topic areas.
As a non-science student, Sections 1 and 2 are your strategic advantage — don't neglect them. Non-science graduates statistically outperform science graduates in these sections, and strong performances here can offset an average Section 3 score.
However, don't assume your existing skills will automatically translate to GAMSAT ® success. Section 1 tests interpretation of diverse texts — including poetry, fiction, and cartoons — and the question format may differ from anything you encountered in your degree. Section 2 requires two essays under tight time constraints, and the GAMSAT ® essay style is quite different from standard academic writing.
Dedicate time to practising under timed conditions. For Section 2, work through practice prompts using our GAMSAT ® Quote Generator and review example essays to understand what markers are looking for. For Section 1, focus on the speed and accuracy of your reading comprehension across unfamiliar text types.
The strategic calculus is straightforward: if you can score highly in Sections 1 and 2 while achieving a solid (not necessarily exceptional) Section 3 score, your overall GAMSAT ® score can be very competitive — particularly at medical schools that weight all three sections equally.
This is a genuine decision point, and the honest answer depends on your circumstances.
Self-study can work well if you have strong self-discipline, ample preparation time (four months or more), access to quality resources, and experience learning technical material independently. Many students prepare successfully using free resources, textbooks, and practice questions alone.
A structured course adds value if your preparation time is limited, you benefit from guided instruction over self-directed learning, you want tutor feedback on your essay writing and reasoning approach, or you find it difficult to know what to prioritise when starting from scratch. For non-science students in particular, a course can prevent the common trap of over-studying content (going too deep into science theory) at the expense of developing reasoning skills.
One of the key advantages of a GAMSAT ® preparation course is access to experienced tutors who have sat the exam themselves and can guide you on where to focus. In a collaborative environment, you can also learn from peers who may have complementary strengths.
Understanding how the GAMSAT ® is scored is essential for planning your strategy as a non-science student.
The ACER overall GAMSAT ® score is calculated as: (Section 1 + Section 2 + 2 × Section 3) ÷ 4. This means Section 3 is double-weighted in the overall score. However, individual medical schools use GAMSAT ® results differently, and this is where strategic thinking matters.
According to the latest GEMSAS Medicine Admissions Guide, several medical schools rank applicants using the overall GAMSAT ® score (which includes the double-weighting of Section 3): ANU, Deakin University, Griffith University, Macquarie University, and the University of Western Australia. Others — including the University of Melbourne, the University of Notre Dame, and the University of Queensland — rank by taking a simple average of the three sections, effectively weighting all sections equally.
Some medical schools weight the sections even more favourably for non-science students. The University of Sydney, for example, places significantly more weight on Sections 1 and 2 than on Section 3, meaning a high Section 3 score is not a strict requirement for a competitive application there.
For a full breakdown of scoring, cutoffs, and percentiles, see our GAMSAT ® Scores guide.
The short answer is: it depends on which medical schools you're targeting. Section 3 contributes significantly to your overall score under the standard ACER formula, so it can't be ignored. But an average Section 3 performance is not a strict barrier — particularly if your Section 1 and Section 2 scores are strong.
At medical schools that use the overall GAMSAT ® score (double-weighted Section 3), a weaker Section 3 carries more consequence. At schools that average the three sections equally — Melbourne, Notre Dame, and UQ — a strong Section 1 and Section 2 can more effectively compensate for an average Section 3.
Other factors matter too. Your GPA, and in some cases your portfolio or interview performance, form part of the overall application. A high Section 3 score helps considerably, but it's one component among several. For full details on how each school weighs these factors, see our medical school entry requirements guide.
Yes — and this is the core strategic insight for non-science students. If you can leverage your humanities strengths to score well in Sections 1 and 2, you create a buffer that takes pressure off your Section 3 preparation.
Here's a simplified illustration of how the scoring works under the standard ACER formula:
| Scenario | S1 | S2 | S3 | Overall Score |
|---|---|---|---|---|
| Strong S1/S2, average S3 | 72 | 70 | 58 | 64.5 |
| Average across all sections | 63 | 63 | 63 | 63.0 |
| Weak S1/S2, strong S3 | 55 | 55 | 70 | 62.5 |
The first scenario — where a non-science student excels in Sections 1 and 2 while achieving a solid Section 3 — produces the highest overall score. At schools using equal weighting (averaging all three sections), the advantage is even more pronounced.
The takeaway: you should absolutely prepare seriously for Section 3 and aim to do as well as you can. But knowing that strong Sections 1 and 2 provide a genuine buffer reduces the pressure and allows you to approach Section 3 preparation with confidence rather than anxiety.
Start with our GAMSAT ® Study Syllabus for a complete topic checklist, then use the dedicated guides for Biology, Chemistry, and Physics to work through each discipline. Free online resources such as Khan Academy are excellent for building foundational science knowledge at the first-year university level. For structured practice, our free GAMSAT ® preparation materials include sample questions and study guides. Once you're comfortable with the basics, move to GAMSAT ® practice questions to apply your knowledge in exam-style conditions. For recommended reading, see our GAMSAT ® textbooks guide.
A realistic target is 10–15 hours per week over four or more months. This is achievable alongside full-time work or study. The key is consistency — regular shorter sessions are more effective than occasional marathon study days. During the early months, weight your study time toward science content learning. As you progress, shift toward practice questions and timed mock exams. Our GAMSAT ® Study Schedule can help you plan a week-by-week breakdown.
Three months is tight for a non-science student, but not impossible — it depends on how many hours per week you can commit. If you can dedicate 20+ hours per week, you may be able to cover the essential science foundations and complete enough practice. However, if your schedule allows only 10 hours per week, you'd likely achieve a better result by targeting a later sitting and preparing over four to six months. Check the upcoming GAMSAT ® dates and plan accordingly.
No. GEMSAS explicitly states that applications from individuals with diverse bachelor degrees are welcomed, and the system does not preference any particular degree. Almost all Australian graduate-entry medical schools have no science subject prerequisites — the exception being the University of Queensland, which requires two specific biomedical science courses. Once enrolled, all students receive the same medical training regardless of their undergraduate background.
Yes — many successful GAMSAT ® candidates prepare while working full-time. The key is starting early enough (allow at least four months for a non-science background) and being disciplined with your available hours. Evening and weekend study sessions of 2–3 hours each, spread across the week, can add up to the 10–15 hours you need. Structured resources like a preparation course or a detailed study schedule can help you make the most of limited time by telling you exactly what to focus on each week.
