The exam is closed book. That's the whole game.
No code book, no notes, no phone - just you, a calculator PSI hands you, and 3.5 hours. Nobody fails because they can't build. They fail because they can't remember whether the down payment cap is $1,000 or 10 percent, how many days a preliminary notice allows, or when final wages are due. CalBuilderPrep drills exactly that: the figure, the rule, and a reason to remember it - checked against the statute so what sticks is right.
+AI tutor, on call 24/7
Miss a question and ask why. The tutor explains it straight, names the law it comes from, and gives you a way to remember the figure - because you cannot look it up on test day.
+343 questions and growing
Written to CSLB's own seven-area content outline, weighted the way CSLB weights the exam, and every one checked against the California statute or official agency page it comes from.
+Full exam simulator
115 questions on the real 3.5-hour clock, mixed across the seven areas at CSLB's weights. CSLB does not publish a question count or a fixed pass mark, so we train you against a 70% bar with margin built in.
+Built for the closed-book test
The dollar thresholds, the day counts, the who-must-do-what - drilled until they stick. Contract rules, wage law, liens, workers' comp, Cal/OSHA, public works, taxes.
+A citation on every answer
Every explanation names the Business and Professions Code, Labor Code, Civil Code or Title 8 section behind it, so you learn the rule and the reason - not just the letter.
+Built for the job site
Runs on any phone. Drill a 10-question round in the truck at lunch - no desk, no classroom, no weekend seminar.
