College Algebra Studio

College Algebra Studio helps you build college algebra skills, one topic at a time. Start with a nine-question readiness check or browse lessons in course order. Each skill includes a short explanation, key formula or notation, a worked example, and practice questions. Answers receive helpful feedback, and you can reveal a hint or worked solution before trying again. Topics begin with sets, number families, and algebra review, then continue through equations, graphs and functions, polynomial and rational functions, inverses, exponents, logarithms, and systems. No account is required. Lessons are free. Public access may show ads; students with an eligible class code can use the app without ads while their code is valid.
