List from the CSLB C-33 study guide. You don't have to buy from the publishers it names: CSLB notes the books are sold elsewhere too.
Painting work runs from bidding and surface prep to coatings, wallcoverings and wood finishes. This sample covers all four CSLB topic areas, so you can spot gaps outside the work you do most often, whether that is interiors, exteriors or wallcovering. Your result shows where to focus next; it does not predict whether you will pass. Full prep adds the complete question bank, saved history and readiness tracking.

It applies to exams scheduled on or after April 27, 2022, so check older material against it. Its link is below, under Sources and method.
It has four areas: Planning and Estimating (28%), Substrate Repair and Surface Preparation (30%), Application of Paint, Wallcoverings, and Finishes (21%) and Safety (21%). CSLB calls the percentages approximate. A painter who mostly rolls and sprays will still see estimating, blueprint, wallpaper removal and Cal/OSHA questions. Take this free test, see which areas you miss, and study those first.
CSLB's guide names the Painter's Handbook, the Painting Contractors Association's industry standards and craftsman manual, the 2025 Cal/OSHA safety orders and EPA's lead-safe renovation guide. The What to read block above lists each one with its publisher.
CSLB says some questions require math and provides a calculator. This sample asks you to turn a wall area into gallons with a waste allowance and to read a wall length off a 1/8-inch plan. Expect areas, gallons per coat, scale, wallpaper rolls and labor cost. Write the units at every step: inches on the plan to feet, square feet to gallons, hours to dollars.
Yes. C-33 is one of the 10 CSLB exams offered in Spanish, and so is Law & Business. If you ask CSLB for a Spanish translator for C-33, you take the Spanish version instead. Test2Pro also works in Spanish, and practice questions can be shown in 8 languages, including Spanish.
CSLB's C-33 description covers preparing surfaces by scraping, sandblasting or other means and applying paints, papers, textures, stains, varnishes, fillers and other coatings that decorate, protect, fireproof or waterproof structures. That is why the exam mixes surface prep, coatings, wallcoverings and wood finishes. For a specific job, read the full classification on CSLB's site.
Within each topic, note whether a missed answer came from math, a surface or product choice, or a safety rule. Rework the calculations first, then review the unfamiliar prep and coating terms before trying another session.
Topic names and weights follow CSLB study guides; practice questions are original Test2Pro content.
