About SAT Prep Hub
SAT Prep Hub is a free, ad-supported study site built for US high school students preparing for the Digital SAT and the ACT. We organise our content the same way the test makers organise their tests — by content domain on the SAT, by reporting category on the ACT — so that the time you spend studying maps directly to the questions you'll see on test day.
Our goal is simple: give every student access to the same structured, rigorous practice that expensive private tutors charge for. There is no paywall, no account required, and no email collection. Every page is fully accessible, server-rendered, and works on any device — from a public-library Chromebook to a parent's old phone.
What we cover
We mirror the official skill taxonomies published by the College Board and ACT, Inc.:
- SAT Math: Algebra, Advanced Math, Problem-Solving & Data Analysis, and Geometry & Trigonometry — the four domains used by the Digital SAT since the spring 2024 transition.
- ACT Math: Pre-Algebra, Elementary Algebra, Intermediate Algebra, Coordinate Geometry, Plane Geometry, and Trigonometry — the six reporting categories used on every ACT math section.
Each topic page contains plain-English concept notes and six worked practice questions calibrated to mirror the difficulty mix of the real test. Past paper breakdown pages map specific real-test questions back to the underlying study topic.
How our questions are written
Our practice questions are generated from category-aware templates, then hand-tuned for clarity. Every question has a fully worked solution that explains the steps — not just the answer. We deliberately avoid trick questions; the goal is to build pattern recognition for the real test, not to play gotcha.
