Solve real chemistry mysteries. Explore molecules, build electrochemical cells, decode spectra, and master organic synthesis — all in one place.
Three ways we make chemistry click — at the macroscopic, molecular, and symbolic level.
Every problem feels like a real experiment. See the scenario, the molecular view, and the challenge — all at once. Chemistry in three dimensions.
Triplet LearningReceive MS, IR, and NMR data one piece at a time. Narrow down the possibilities. Deduce the mystery molecule — just like a real analytical chemist.
Unit 4 SignatureNavigate interactive concept maps. See how skills connect. Build synthesis pathways. Watch equilibrium shift in real time.
InteractiveEach unit builds on the last. Master the foundations, then tackle the exam-critical content.
Atomic structure, electron configuration, periodic trends, Lewis structures, VSEPR shapes, bonding types, intermolecular forces, mole calculations, organic families, polymers, green chemistry
Explore Unit 1Water chemistry, acids & bases, pH calculations, redox reactions, half-equations, stoichiometry, titrations, gas laws, volumetric analysis
Explore Unit 2Fuels & energy, calorimetry, galvanic cells, electrochemical series, Faraday's law, fuel cells, collision theory, Le Chatelier's principle, equilibrium constants, ICE tables, acid-base equilibria
Explore Unit 3Functional groups, IUPAC naming, organic reactions, synthesis pathways, yield & atom economy, mass spectrometry, IR spectroscopy, NMR spectroscopy, HPLC, medicinal chemistry
Explore Unit 4Every skill targets the exact knowledge and skills assessed by VCAA.
Quality over quantity. Each skill has 3 adaptive difficulty levels with 15-25 curated questions per level, giving 5,000+ unique problems. Every question uses real chemical data, real-world scenarios, and step-by-step solutions that teach the thinking process. 130 deep skills beats 500 shallow ones.
If you're in Year 12, start with Units 3 and 4 — they contribute 100% of your ATAR study score (25% Unit 3 SAC + 25% Unit 4 SAC + 50% exam). If you're in Year 11, Units 1 and 2 build the foundations you'll need later.
Every skill maps directly to a key knowledge point in the VCAA Chemistry Study Design 2023–2027. We match the Data Book constants, follow IUPAC conventions, and use VCE-standard notation throughout.
Every question opens with a real-world scenario — forensic chemistry, sports science, battery technology, medicine. Solutions don't just show the answer; they explain WHY each step works, flag common traps, and connect abstract chemistry to what you can actually observe.
Our signature Unit 4 feature. You receive mass spectrometry, IR, and NMR data one piece at a time and progressively narrow down the mystery molecule's structure. It's exactly how real chemists work, and it's the most engaging way to master the most exam-critical skill in VCE Chemistry.
