Develop the skills to tackle one of the most cognitively demanding GAMSAT formats: spatially complex, systems-based reasoning in electrical and biological circuits. This week focuses on how ACER reimagines traditional physics content—such as electric fields, forces, and circuit equations—as spatial reasoning challenges embedded in biological contexts.

You will explore the foundational logic of series and parallel circuits and learn how these principles are increasingly applied to biological systems, particularly cardiovascular flow diagrams. Recognising this recent trend, the course equips you with the conceptual clarity and analytical tools to interpret circuit-based stems that blend physical processes with anatomical function.

💡 Key Topics:

• Core principles of electrostatics and circuit theory: electric fields, forces, capacitance

• Solving series and parallel circuit problems with emphasis on current, voltage, and resistance

• Translating electrical logic into biological systems: vascular flow and resistance

• ACER’s spatial geometry approach to diagrammatic reasoning in mixed-system questions

🧠 Core Skills You’ll Build

• Systematic variable tracking in multi-component circuits

• Spatial reasoning with layered diagrams and flow-based systems

• Translating physical laws into real-world biological scenarios

• Deconstructing ACER-style questions using the scientific method

• Problem solving under cognitive load using systems equilibrium thinking

🎯 Why This Is High-Yield

Electric circuits and vascular analogies appear frequently in ACER exams and are often disguised in complex, data-heavy stems. Mastering this content gives you a strategic advantage in Section 3 by helping you solve some of the most scoring-efficient questions using structured, transferable reasoning techniques.
