GAMSAT physics: the topics actually worth knowing
You don't need a physics degree for Section III — but a focused core pays off. Here are the physics topics worth knowing and the maths that goes with them.
Physics intimidates a lot of GAMSAT candidates, especially those who dropped it after school. But Section III physics rewards a focused core plus comfort with simple maths — not deep, specialised knowledge. Here's where to aim.
The core worth knowing
| Area | What recurs |
|---|---|
| Mechanics | Kinematics, Newton's laws, forces, equilibrium |
| Energy & work | Work, power, conservation of energy, momentum |
| Waves & sound | Wavelength/frequency, the wave equation, basic behaviour |
| Optics | Reflection, refraction, lenses |
| Electricity | Current, voltage, resistance, simple circuits |
| Heat | Temperature, heat transfer, basic thermodynamics |
A working grasp of mechanics and energy alone covers a surprising amount, because the exam loves problems where you apply a formula to an unfamiliar setup.
The maths matters as much as the physics
Most physics questions are really applied maths under time: rearranging an equation, reading a graph's gradient, keeping units straight, handling powers of ten. If formula rearrangement or unit conversion is shaky, fixing that lifts your physics score faster than learning more physics.
What's lower-yield
You don't need university-level depth in any one area. Specialised topics that rarely appear aren't worth months of study. Breadth across the core, with the confidence to apply a formula you're given, beats depth in a corner.
Practise applying, not memorising
Section III physics gives you the relationships you need — the test is whether you can use them on a novel problem. Drill that, with the clock on. See how GAMSAT physics is examined and start applying the core to fresh questions.
Key takeaways
- A focused core — mechanics, energy, waves, optics, electricity, heat — covers most of it.
- Physics questions are really applied maths under time.
- Shaky formula-rearranging or units cost more marks than any single topic.
- Specialised depth is low-yield; breadth plus confident application wins.
