01
Pick a topic
Choose one of the Science in Practice topics above or type your own, then pick your state. WACE, VCE, HSC, QCE and SACE each word their questions differently, and the paper follows yours.
02
Attempt it yourself
Exam-style questions with the mark allocation showing, so you know how much to write. You answer them — nothing is handed to you.
A school wants to reduce the energy used by its computer lab. Describe how you would test which change saves the most energy, and explain how you would judge whether the change was worthwhile. (6 marks)
03
Get it marked
Your answer comes back marked criterion by criterion in seconds — what you earned, what you half-earned, and what the examiner never saw.
4/6 · ✓ Names a measurable quantity and an instrument to measure it
04
Fix the gap
The topics you keep losing marks on come back around in your review until they're strong. That's the whole point.

✓ Uses a before-and-after comparison to test the change
✕ Controls the comparison — same period, same number of machines, same usage
✕ States the criteria for worthwhile: energy saved against cost and disruption
