Stop Wasting Time. Start Practicing.
The official CSLB Law & Reference Book is over 400 pages of dense legal text. Our guide condenses it into 300+ exam-realistic questions that target the key information you actually need to know to pass.
Focus on the Core Topics You MUST Know
Business & Licensing
Master questions on business organization, licensing requirements, and advertising rules.

Why Reading the Study Guide Isn't Enough
Many contractors fail because the real exam asks tricky, scenario-based questions that the manual doesn't prepare you for. Our practice test bridges that gap by training you on the *style* and *format* of the actual CSLB exam.
"I failed the Law & Biz exam once and was about to pay $300 for a weekend class. Found this guide instead. The questions were extremely similar to the real test. Passed easily the second time. A no-brainer for the price."
- Carlos G., General B Contractor, San Jose
"As a plumber, I know my trade, but the business law stuff was intimidating. This practice exam made it simple. I studied the PDF for a week and walked into the test with total confidence. Highly recommend."

Try a Few Free Questions
1. What is the maximum legally allowed down payment for a home improvement contract in California?
Correct Answer: 10% of the contract price or $1,000, whichever is less. This is a critical consumer protection law that all contractors must follow for residential projects.
2. A subcontractor who is not paid must serve a "Preliminary Notice" to the property owner within how many days of first furnishing labor or materials?
Correct Answer: 20 days. Serving this notice is a prerequisite for preserving the right to file a mechanic's lien later.
