Pick a topic
Choose one of the Science Extension 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 student reports that their treatment group had a higher mean growth rate than the control (p = 0.04) and concludes that the treatment causes faster growth. Assess this conclusion. (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 · ✓ Interprets p = 0.04 correctly against the 0.05 threshold
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.
