HSC Economics track

Your whole syllabus, but it moves

Every HSC Economics topic mapped to the interactive model that teaches it. Learn the diagram, animate real Australian scenarios (the mining boom, RBA rate calls, the GST), then drill it in quiz and exam mode before trials.

Common questions

What diagrams do I need to know for HSC Economics?

The essentials are supply and demand (with ceilings, floors, and surplus), production possibilities, the labour market, AS-AD for every macro policy question, the Phillips curve, the money market for cash-rate questions, and exchange-rate diagrams for Topic 7. Every one of them is an interactive model on this page: you can move the curves, animate real events, and quiz yourself until the shifts are automatic.

How do I get better at economics diagrams quickly?

Practise the shift, not the picture. Most marks are lost on which curve moves and which way, not on drawing. Graphl's quiz mode gives you a real-world event and makes you drag the correct curve in the correct direction, with instant feedback; ten minutes a day beats re-reading notes.

Is Graphl free for HSC students?

Yes. All 51 interactive models, every explainer, the glossary, live economic data, and the daily Graphdle puzzle are free. Graded practice has daily free limits; Pro removes the limits for $4 a month.

How should I revise economics the week before trials?

Sit one timed exam per day scoped to your weakest topics, review what the score report flags, then replay the specific scenarios you missed. Finish each session with the daily Graphdle to keep diagram recognition sharp under time pressure.
