AP Chemistry rewards steady, active revision far more than last-minute cramming — yet most students still study by re-reading notes the night before a test. We built ipassed.gg to change that: to turn AP Chemistry prep into short, daily, mastery-based practice that builds real confidence across all nine units of the College Board Course and Exam Description (CED).
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 College Board AP Chemistry Course and Exam Description, covering all nine units — from atomic structure and bonding through intermolecular forces, reactions, kinetics, thermodynamics, equilibrium, acids and bases and electrochemistry — together with the Science Practices the exam tests: models and representations, mathematical routines, experimental design and argumentation.
We are a small team of educators who know how demanding international science exams can be. We understand the precise wording, task verbs and depth that the College Board looks for, and we design every question and note with that in mind — not just to test you, but to teach you.
