    Free 2026 CSLB Law and Business Practice by Topic

    This free California contractor practice tool is built around the seven topic areas that appear on the CSLB Law and Business examination. Rather than working through questions at random, you can focus your study time on the specific subjects where you need the most improvement. Select a topic, work through questions at your own pace, and build the targeted knowledge you need to pass.

    Target your weak areas by selecting any of the eight available categories:

    • All Topics
    • Business Organization and Licensing
    • Business Finances
    • Employment Requirements
    • Insurance and Liens
    • Contract Requirements and Execution
    • Public Works
    • Safety

    Each category draws from a bank of 1,400+ questions, giving you plenty of material to practice with until you feel confident in every subject area.

    Each question matches the format and difficulty of the actual CSLB Law and Business exam. After selecting an answer, you get immediate feedback with the correct answer and the relevant California code reference. This helps you understand not just what the right answer is, but why it is correct, so you can close knowledge gaps and walk into exam day fully prepared.

    Ready to test your overall readiness? The Simulate Exam practice mode gives you a timed 115-question session that mirrors real exam conditions, including the same time pressure you will face on test day.

    For a structured study plan that walks you through each topic area in detail, visit the CSLB Law and Business Exam Study Guide in the Guides section.

    Feedback is welcome on both the structure of the practice tool and the quality of individual questions. You can flag a specific question right after answering it, or send general comments using the "Send us feedback" link at the bottom of the page. Your input helps improve the experience for every contractor studying for this exam.
