Master Every Tested Subject. Pass the First Time.
California contractor exams are closed book, so the only thing walking into that testing center with you is what you’ve learned. Our California courses are built from the ground up for that reality — organized subject by subject around the official CSLB test plan, so every minute you study is aimed at what’s actually on the exam.
Prepare for the California General Building (B) Contractor License Examination with 1 Exam Prep's online exam preparation course. Designed for construction professionals pursuing their California Class B General Building Contractor license, this course provides organized instruction, focused study materials, practice questions, and comprehensive examination review.
California general building contractors work on residential and commercial construction projects involving multiple building trades. Preparing for the Class B examination requires knowledge of construction planning, estimating, framing, structural components, plumbing, electrical systems, roofing, finish work, and occupational safety.
Our online course breaks these complex subjects into manageable lessons designed to strengthen technical understanding, reinforce important concepts, and help students prepare for the closed-book examination administered by the California Contractors State License Board (CSLB).
Instead of spending hours searching through lengthy construction manuals, students follow an organized study program focused on the subjects identified in the official CSLB examination study guide.
Every tested subject gets the same four layers, in the order that makes the material stick:
Each learning layer builds on the previous one. Students first develop an understanding of construction concepts, reinforce terminology through reading, review essential information using cram sheets, and practice applying that knowledge through examination-style questions.
This structured approach helps transform complicated construction subjects into organized study sessions while encouraging consistent learning and stronger retention.
Once you’ve worked through every subject, the final phase pulls it all together:
Learn it. Reinforce it. Condense it. Test it. Then prove your knowledge on a full-length final examination. This preparation method helps students identify subjects requiring additional attention, strengthen recall, and approach their first examination attempt with confidence.
The California General Building (B) Contractor Examination evaluates a candidate's knowledge of construction planning, structural components, core building trades, finish construction, and workplace safety.
The official CSLB General Building (B) examination study guide, effective for examinations scheduled on or after January 1, 2025, identifies five major examination sections:
These percentages represent the approximate distribution of examination subjects. Core Trades accounts for the largest portion at 30%, making it an especially important area of preparation.
The examination uses multiple-choice questions with four possible answers and one best answer. Some questions require mathematical calculations, and a calculator is provided during testing.
Our California General Building exam prep course follows the major CSLB examination subjects to help students concentrate on relevant construction knowledge and prepare through targeted review.
The California General Building (B) Contractor Examination is closed book. Reference books, manuals, notes, and other study materials cannot be used during the examination.
Because candidates must rely on retained knowledge, preparation requires understanding construction procedures, remembering important building requirements, recognizing job site hazards, and applying technical principles independently.
Our California General Building online course is specifically designed for this testing environment. Lessons are organized around official CSLB examination subjects and the construction reference materials associated with those subjects.
Instructor-led videos explain essential concepts, reading chapters reinforce understanding, cram sheets simplify review, and practice questions help students apply what they have learned.
Full-length practice examinations provide additional opportunities to evaluate knowledge without depending on outside reference materials.
California General Building Contractors must obtain the appropriate Class B contractor license through the Contractors State License Board before performing contracting work requiring that classification.
The general licensing process includes:
This product provides California General Building (B) trade examination preparation only. California Law and Business Exam preparation, application assistance, state licensing fees, and contractor bond services are separate from this online course purchase.
California regulates general building contractors through the Contractors State License Board. Business and Professions Code Section 7057 establishes the Class B General Building Contractor classification.
The classification generally applies to contractors whose principal business involves structures requiring the use of at least two unrelated building trades or crafts.
General building contractors may perform qualifying residential and commercial construction projects and coordinate appropriately licensed specialty subcontractors within the scope allowed by California law.
Framing and carpentry projects have specific treatment under the Class B classification. Other single-trade projects are subject to additional classification and subcontracting limitations.
Applicants pursuing initial licensure generally must demonstrate qualifying experience, submit the appropriate application, and satisfy applicable examination requirements unless an authorized exemption or waiver applies.
California contractor licensing also involves appropriate bonding and other business responsibilities. Contractors must work within their authorized classification and comply with applicable building, environmental, and occupational safety requirements.
The courses are based on the following reference books (not included).
Please Note: No physical or digital reference books are included with this online course. The course provides structured examination preparation based on the listed reference materials and official CSLB General Building examination subjects.
Effective preparation for the California General Building (B) Contractor Examination requires knowledge of construction planning, building materials, structural components, building systems, finish work, and job site safety.
Planning and Estimating: Students should understand how to interpret plans and specifications, identify construction errors, evaluate project requirements, estimate quantities, and coordinate building activities.
Framing and Structural Components: Important topics include floor framing, wall framing, roof construction, seismic hardware, siding, stucco, decks, and stair construction.
Core Building Trades: Study plumbing systems, electrical installations, HVAC principles, concrete construction, roofing, insulation, weatherproofing, earthwork, and surveying.
Finish Construction: Review drywall, plaster, painting, flooring, cabinetry, millwork, tile, stone, doors, windows, and other finishing methods.
