Every A-level topic in depth — core, worked examples, exam tips and 🎓 extended material beyond the syllabus. Open a chapter in ⤢ Study Mode for a distraction-free read with a 5-question check at the end.
Simulations
Play with the variables the syllabus says matter. Every curve is computed live from the real equations.
Periodic table
All 118 elements, alive. Paint the table by electronegativity, ionisation energy, radius or melting point — or grab the temperature slider and watch every element freeze, melt and boil from absolute zero to the surface of the Sun. Hover anything for details, click for its full profile, then race the clock in Element Hunt.
The required practicals
All 12 AQA required practicals as guided Lab Mode walkthroughs — one clear step at a time, with the full detail on tap, CLEAPSS/RSC safety, the mistakes examiners report every year, and spot-the-mistake challenges at the end.
Quick-fire quiz
One question at a time with instant marking, explanations and streaks — shuffled every session. Protect your streak. 🔥
Exam-like questions
Original questions in real exam formats, on a real exam clock — 1 minute per mark. Written answers are marked by an AI examiner who explains exactly where the marks were lost.
🏆 Ranked
Climb from Lab Rat to Nobel Laureate on Research Points. Perfect papers pay the most, quiet days cost you, and only Laureates mint 🧪 test tubes for the leaderboard.
🔥 Redemption
Every question that has ever beaten you waits here, haunting your scores. Answer one correctly to light an ember — two embers and it burns away for good. Get it wrong again and the embers go out. Clear the room and the slate is clean.
