Sample Practice Question
A contractor is estimating a job that involves pouring a new concrete slab. Which of the following has the most direct effect on how thick the slab needs to be?
Slab thickness is primarily driven by the load it needs to support — vehicle traffic, foundation walls, and so on — not by finish, brand, or season. The full B General guide covers load calculations like this in depth.

Business Org & Legal
What's the general purpose of a contractor's license bond?

Sample Practice Question
A contractor buys materials for $1,000 and sells the completed job for $1,300. Which pricing concept describes that $300 as a percentage of the selling price rather than the cost?
Margin measures profit as a percentage of the selling price. Markup measures it as a percentage of the cost — mixing the two up is one of the most common exam traps, and the full Law & Business guide breaks it down with worked examples.

Do I need both exams, or can I buy just one?
Most CSLB applicants need to pass both the trade exam and Law & Business, so we offer a complete bundle at a discount.

When you're ready to apply for your license, call the number from your confirmation email or reach out to Evercrest Builders directly — we'll personally help you through the CSLB application process, bonding, and everything else involved.

We offer a 7-day satisfaction guarantee — if the guide isn't a good fit, email info@evercrestbuilders.com within 7 days of purchase for a refund.
