GAMSAT Key Concepts in Physical Science

Posted by Mat on Jan 18, 2019 11:09:24 AM

GAMSAT candidates often ask how to study for GAMSAT Section III. A useful way to begin can be to focus on the physical sciences and work your way up.

The physical sciences lie at the heart of all the other disciplines relevant to Section III of GAMSAT. This is reflected in the hierarchy of sciences:



The division of sciences in GAMSAT is loosely as follows:

  • Biology: 20%

  • Physiology: 20%

  • Organic chemistry: 20%

  • Physical chemistry: 20%

  • Physics and mathematics: 20%

Therefore around 40% of the Section III exam is comprised of what would be classified as ‘hard’ or classical sciences in the form of physical chemistry, physics, and mathematics. The other sciences are more applied. What this means is that the higher-level sciences describe concepts not based on their own laws or general principles. Subjects such as biology and physiology (and medicine) are somewhat arbitrary in that their level of focus is not premised on universal laws. This makes them less efficient to study, but in some instances more interesting.

The ‘softer’ sciences are however premised in the universal laws of physics (ergo mathematics). This is an important consideration for those preparing for GAMSAT as there is significant yield in comprehensive study of the physical sciences. Consider the following key broad physical concepts:

  • Energy and heat

  • Temperature

  • Matter and mass

  • Pressure

  • Volume

  • Force

  • Charge

Now consider the application of these principles in their native and foreign contexts. The above seven concepts represent the most important concepts in physics and physical chemistry, but also in organic chemistry, and physiology. The principles underpinning these concepts are also responsible for the biological processes many candidates study for GAMSAT.

Understanding the above seven physical concepts is by far the highest-yield approach to studying Section III. It is these concepts that students should always seek to relate their understanding of scientific systems.

In next week’s webinar, we will discuss how students can use these key physical concepts to improve their performance in Section III of GAMSAT.
