About This Site
Contractor-Prep.com is a free practice exam tool for the California CSLB Law and Business Exam. No account, no paywall, no fluff.
What This Tool Does
Two practice modes. Simulate Exam mode gives you a timed, randomized 115-question session that mirrors the real test format. Practice mode lets you work through all questions at your own pace with instant feedback after each answer.
Detailed explanations. Every question includes an explanation for each answer choice, not just the correct one. Wrong answers are explained too, so you understand why they fail and how to spot similar traps on the real exam.
Covers all seven exam topics. Questions are drawn from the same competency areas the CSLB tests: Contract Requirements, Employment, Business Finances, Safety, Licensing, Insurance and Liens, and Public Works.
About the Exam
