AP Precalculus 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 AP Precalculus revision into short, daily, mastery-based practice that builds real confidence across the whole College Board course framework, ready for the AP exam.
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 Precalculus course framework, covering all four units — Polynomial and Rational Functions; Exponential and Logarithmic Functions; Trigonometric and Polar Functions; and Functions Involving Parameters, Vectors, and Matrices — with the multiple-choice and free-response skills the AP exam rewards. (The exam itself assesses Units 1-3.)
We are a small team of educators who know how demanding AP Precalculus can be. We understand the precise wording, command terms and methods that College Board examiners look for — from "show that" proofs to multi-step problem solving — and we design every question and note with that in mind, not just to test you, but to teach you.
