Pick a topic
Choose one of the General Mathematics 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 town’s population moves between the city and suburbs each year according to a transition matrix. Given the current state vector, determine the population distribution after two years and explain what a steady state would mean here. (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 · ✓ Applies the transition matrix in the correct order to the state vector
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.

General Mathematics · VCE
Marked in seconds
✓ Applies the transition matrix in the correct order to the state vector
✓ Repeats for the second year to obtain the two-year distribution
✕ States the resulting numbers with the correct rounding for a population
✕ Explains the steady state in context — movement continues but the distribution no longer changes
