New topic: Space & Universe
A brand-new Year 9–10 topic with 80 questions across 8 levels — the solar system, stars and their life cycles, galaxies, the Big Bang, gravity and orbits, and space exploration.
❓
Smarter, more varied questions
Over 130 new curriculum-aligned questions added across every year level. Instead of ‘What is…’, these ask How, Why, Where, When, and What would happen if — building genuine understanding, not just recall.

Practice difficulty levels
The Practice screen now lets you choose Beginner, Intermediate, or Advanced. It maps to the right level for each topic automatically — including the 20-level Year 9–10 courses.
🎊
Celebrations & level-up
Hit 3 stars and confetti bursts across the screen. Cross a new XP threshold and a full celebration modal appears with orbiting sparkles and your new rank title — from Lab Novice to Science Royalty.
