01
Pick a topic
Choose one of the Earth and Environmental Science 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 geological cross-section shows a granite intrusion cutting through folded sedimentary layers, with an unconformity above them. Determine the relative order of events and justify your answer. (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 · ✓ Correct order of events from oldest to youngest
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.

Marked in seconds
✓ Correct order of events from oldest to youngest
✓ Uses cross-cutting relationships to place the intrusion after folding
△ Names the principle of superposition for the sedimentary sequence
△ Identifies the unconformity as a period of uplift and erosion, not just deposition
