IB 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 IB Chemistry revision into short, daily, mastery-based practice that builds real confidence across the whole IB Chemistry syllabus, at both Standard and Higher Level.
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 IB Chemistry syllabus (first assessment 2025), covering all six themes — Structure 1–3 (the particulate nature of matter, bonding and structure, classification of matter) and Reactivity 1–3 (what drives reactions; how much, how fast and how far; and reaction mechanisms) — across both Standard and Higher Level, including the calculation and data-booklet skills the papers expect.
We are a small team of educators who know how demanding IB science can be. We understand the precise wording, command terms and depth that IB examiners look for, and we design every question and note with that in mind — not just to test you, but to teach you.
