Why Particle
The difference between practising and just reading
Marked like a real examiner
Not multiple choice. Particle reads your written, working-and-all responses and marks them against NESA-style bands — with a per-mark breakdown of exactly where you won and lost marks.
Sit it like the real thing
Focused exam-mode sessions: pick your topics, set the clock (or don't), and work through a paper one question at a time — timer, navigation and all.
Built on the syllabus, not vibes
Every question is bounded to the NSW Stage 6 syllabus, down to the dot point. Physics and Chemistry, Year 11 and 12 — nothing off-course.
Feedback in seconds, any hour
A marker in your pocket at 11pm before an exam. Instant, specific, and always available — for a fraction of the price of a tutor.
Study with your fireteam
Form a fireteam with your mates, pool your progress, and see who's putting in the work on a shared leaderboard. Invite a friend and you both earn bonus marking credits.
Learn it first — free
Stuck on a topic? The free Learn section covers every syllabus topic across both subjects with clear notes and diagrams, then drops you straight into practice.
Compete
Practice that actually counts for something
Every question you answer climbs you up the live leaderboard. Start a fireteam with your mates, compare on a shared board, and keep each other honest. School-vs-school and an ELO rating are on the way — bragging rights, backed by marks.
