How to use this site
Pick the entry point that matches where you are in your preparation:
Take a free sample
New here? The 7-question mixed sample needs no account. You get instant feedback and the source citation after each answer.
Run a full practice test
Sign in (it's free), then choose 10, 25, 50, or 115 questions. Study mode explains each answer as you go. Exam mode is timed like the real exam and grades you at the end, section by section.
Study by section
Every official exam section has a study note with citations to the California sources behind it. Review a section between practice runs, or look up the rule behind a question you missed.
Check exam logistics
Before test day, know the rules: 3.5 hours at a PSI testing center, closed book, government photo ID, and no phones or notes. There is no penalty for guessing, so answer every question.
Look up the law
Already licensed, or studying a rule you keep missing? Ask the library answers questions about California contractor law and business from a dated, cited snapshot of statewide statutes and regulations — and it refuses to answer when the snapshot does not contain the support.
CSLB practice test questions
Is the CSLB Law and Business practice test free?
Yes. The 7-question sample needs no account. Full tests are also free after sign-in: choose 10, 25, 50, or 115 questions. No payment is required.
Are these official CSLB exam questions?
These are original practice questions written from official California sources and reviewed before use. They are not official exam items. Contractor Law Class is independent and is not affiliated with CSLB or PSI.
How does study mode differ from timed practice?
Study mode has no timer and shows an explanation and citation after each accepted answer. Exam mode saves feedback until submission. This site's longest timed practice test has 115 questions and a 210-minute timer.
How long should I study for the CSLB Law and Business exam?
Your preparation time depends on your experience and familiarity with the seven sections. Start with mixed practice, review the sources behind missed answers, and spend more time on sections where your results are weaker. Use timed practice to check your pace. A practice score cannot guarantee an official exam result.
