Our commitment to access
We are a group of young science teachers based in Singapore.
We believe in freebies access. Educational resources should be accessible to all, both financially and conceptually. So we are committed to keeping everything on the website free. Let there be no paywall, subscription fee, or DLC. We also use plain language and memes analogies familiar to the young in Singapore.
We believe in diversity. We respect that every child has a unique learning style. That’s why we have multiple authors to write about Chemistry from different angles, with different voices. We hope you can find articles that speak to you, that enrich your learning.
Surely, our notes will help you overcome the O Level Chemistry exams. But life is more than that, and Chemistry too. We will show you the exciting aspect of Chemistry through our stories on everyday applications, folk knowledge, history of science, philosophy, and the latest scientific breakthrough.
