GAMSAT Section 3: Reasoning in Biological and Physical Sciences

gamsat section 3

Section 3 is the longest, and often most daunting GAMSAT section. This section is also perceived to be the ‘core’ of the GAMSAT exam. The unwarranted anxiety that this section causes students, is likely what causes them to pursue extremely inefficient GAMSAT preparation strategies. This is the third article in a series helping candidates better understand the GAMSAT. By dissecting this section at a fundamental level, we can begin to look at the possible ways any students can achieve a high section 3 score.

What is the Purpose of GAMSAT Section 3:

In the previous articles from this series, we have discussed how Sections 1 and 2 mirror the sequence events when a doctor (or medical student) encounters a patient in the hospital. In our article about Section 1, we discussed how reading comprehension texts test a candidate’s ability to understand and empathise with a patient. Section 2, on the other hand, examines a GAMSAT student’s capacity to clearly communicate information to their patient. We have now arrived at Section 3, which is the final, and arguably most critical, element of the patient interaction – the biomedical management itself! Often, especially in the early years of training, medical students and doctors encounter familiar problems in an unfamiliar context. For example – as a student you may learn about the causes of infection, however this does not mean that you will instantly be able to diagnose every infection on the spot! In fact, you will often be forced to refer to scientific literature, sometimes in time-pressured conditions, to make critical care decisions for patients under your care. This is exactly what section 3 of the GAMSAT exam is attempting to emulate. 

What is the GAMSAT Syllabus for Section 3

ACER, the company responsible for designing and conducting the GAMSAT exam, has given an explicit breakdown of the GAMSAT section 3 questions topics. As of 2021, the 75 questions in section 3 of the GAMSAT exam will distributed as follows:

  • 40% allocated to 1st year university-level Biology
  • 40% allocated to 1st year university-level Chemistry
  • 20% allocated to Year 12 level Physics

The conclusions drawn from this information should dictate your GAMSAT preparation, and can make or break your performance on exam day. Not only is a strong understanding of the principles in each aspect of the GAMSAT syllabus for section 3 important for performing well during the exam – these principles are also the bedrock of your medical studies. 

Many students however, see the percentage breakdown on ACER’s guide and are led to believe that reading textbooks and writing pages of summaries will fill the knowledge gaps necessary to score highly in Section 3. However, on exam day it quickly becomes apparent that accumulation of biology, chemistry, and physics facts and formulas during GAMSAT preparation does not translate into the exam. We have already touched on the reason for this – the specifics of the questions are almost always unfamiliar to students. What ACER is, in fact, conveying to candidates, is that 40% of questions will draw on logic and concepts from the GAMSAT biology topics that are included in 1st year university courses. 

To illustrate this further, consider the following simplified physics question example: A kangaroo uses its legs to hop, and its tail as a counterbalance – what is the torque occurring at the knee joint of the kangaroo? Very few (if any) students would have any experience with the mechanics of kangaroo locomotion. However, a prepared student would be well aware of the concept of torque in physics. No quantity of formula memorisation, or note-writing would allow a student to anticipate a question concerning the physics of kangaroo movement. A student with a strong understanding of the physics concept of torque however, should be able to understand the context of the question, effectively utilised the further provided formulas, and put the information together in an appropriate way to respond.

It is for this reason that practising the logic and reasoning facet of answering GAMSAT section 3 questions is far more effective than textbook rote-learning. Candidates should accept that the majority of technical information is provided for this within the GAMSAT exam. This means that the most effective GAMSAT section 3 strategy is learning to interpret the novel data provided, rather than attempting to anticipate the specific topics the exam will cover. 

How to Approach GAMSAT Section 3 Questions:

It is certainly true that the GAMSAT is constantly evolving. However, since its conception in 1995, the GAMSAT section 3 questions have shifted away from testing technical memorisation, and application of formulas and facts (as in standard university exams) and towards psychometric testing.  Recent GAMSAT candidates consistently state that this test is a middle-ground where background biomedical science knowledge meets abstract critical reasoning. This means that background study of the GAMSAT biology, chemistry, and physics syllabi certainly has its place. This should however, be no greater than half of your GAMSAT section 3 strategy.  Understanding the context knowledge partway. 

Unlike the straightforward recollection of facts you may require for university examinations, you need to have a deeper understanding of the implications of the contents of section 3 topics such that you can apply abstract scientific concepts to the unfamiliar themes in the question stems. In more practical terms, it is not enough to remember GAMSAT physics equations describing the relationship between (for example) pipe diameter and water pressure – you must also understand why this is the case. This profound understanding of GAMSAT section 3 question content also allows for integration of knowledge across disciplines – for instance, how would the aforementioned pipe differ if it was, in fact, a blood vessel rather than a gardening hose.  

The above reasons are explicitly why, at Fraser’s GAMSAT, we break down section 3 preparation into classes and exercises focusing on knowledge and cognitive components respectively. The cognitive element of section 3 prepares you for the flexible, and integrative problem solving that GAMSAT Section 3 demands, while our knowledge provides context and allows for quick question orientation.

In brief, these are the science topics required. Though be warmed – use this resource with care such that you do not encounter the common GAMSAT student pitfall of having all your time consumed by making GAMSAT biology/chemistry/physics notes rather than solving GAMSAT section 3 practice questions.
