Textbooks and the syllabus have mistakes. This site has them all fixed.
For example there are incorrect hydrogen bonding explanations, wrong notation (C vs c), incomplete organic synthesis diagrams, missed concepts such as Hess’ Law and many other errors including errors of omission. These are published resources so you are stuck with them for years, however, here any improvements are made as soon as they are discovered.
Always QLD-current.
Fully aligned to the latest QCAA syllabus — no outdated content, no guesswork.
Nothing gets skipped.
If a lesson is rushed or missed at school, the content is still covered clearly and completely. Learn concepts before class, practise in class — this is flipped learning and one of the most effective ways to learn science. See this video to understand how flipped learning is better.
Everything in one place.
Support for struggling students and extension for top performers — no extra resources needed. Online flashcards, marked online quizzes, full experimental video playlists and much more.
