Cambridge IGCSE Chemistry rewards steady, active revision far more than last-minute cramming — yet most students still revise by re-reading notes the night before a test. We built ipassed.gg to change that: to turn IGCSE Chemistry revision into short, daily, mastery-based practice that builds real confidence across the whole 0620 / 0971 syllabus, Core and Extended.
Everything here is built around two ideas proven to make knowledge stick — active recall (retrieving facts from memory) and spaced repetition (revisiting them over time):
Our content follows the current Cambridge IGCSE Chemistry 0620 / 0971 syllabus, covering all 12 topics from states of matter and atomic structure through stoichiometry, acids and bases, the Periodic Table, metals, organic chemistry and chemical analysis — including the experimental and analysis skills that the written papers expect.
We are a small team of educators who know how demanding international science exams can be. We understand the precise wording, command terms and depth that Cambridge examiners look for, and we design every question and note with that in mind — not just to test you, but to teach you.
