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 your California Class B General Building Contractor License with 1 Exam Prep's Business & Trade Online Courses. This package combines General Building (B) Trade Exam preparation with California Law and Business Exam preparation, helping aspiring contractors develop both the technical construction knowledge and business understanding needed for the California licensing examinations.
California general building contractors oversee residential and commercial construction projects involving multiple trades. Successful preparation requires knowledge of construction planning, estimating, framing, structural components, plumbing, electrical systems, roofing, finish trades, and workplace safety.
Our online courses transform these subjects into manageable lessons supported by instructor-led videos, reading chapters, cram sheets, practice questions, and comprehensive final examinations.
Both the General Building (B) Trade Course and California Law and Business Course are included. Physical and digital reference books are not included with this package.
Every tested subject gets the same four layers, in the order that makes the material stick:
Each learning layer reinforces the previous lesson. Students begin by understanding important construction or business concepts, strengthen their knowledge through reading, review essential details using cram sheets, and practice answering examination-style questions.
This approach creates a consistent study routine across both courses while helping students identify subjects that require additional attention.
Once you’ve worked through every subject, the final phase pulls it all together:
Learn it. Reinforce it. Condense it. Test it. Then prove it on a full-length final — that’s how our students prepare to pass the first time.
Practice finals help students evaluate their understanding across multiple subjects, improve familiarity with examination-style questions, and develop confidence before entering the testing center.
The California General Building (B) Contractor Licensing Exam Prep Business & Trade Online Courses package includes:
Important: This package includes Business and Trade online examination preparation only. No physical or digital reference books are included. Application assistance, state licensing fees, and contractor bond services are not part of this package.
The California General Building (B) Contractor Examination evaluates knowledge of building construction, project planning, structural systems, core construction trades, finish work, and occupational safety.
The official CSLB General Building (B) examination study guide identifies five major examination categories:
These percentages represent the approximate examination content distribution. Core Trades is the largest category at 30%, followed by Framing and Structural Components and Finish Trades at 20% each.
The examination consists of multiple-choice questions with four possible answers and one best answer. Some questions require mathematical calculations, and a calculator is provided during testing.
Our course follows these major examination categories to help students study relevant construction practices and understand the connections between different building trades.
Both the California General Building (B) Trade Examination and California Law and Business Examination are closed book. Reference books, manuals, notes, and other study materials cannot be used during testing.
Because candidates must rely on retained knowledge, effective preparation requires understanding construction procedures, recognizing building requirements, remembering safety practices, and applying business concepts independently.
Our California contractor exam prep courses are specifically designed around the examination subjects and associated reference materials to help students build the knowledge needed for closed-book testing.
Instructor-led videos explain concepts, reading chapters reinforce understanding, cram sheets support memorization, and practice questions help students apply their knowledge.
Full-length practice examinations provide additional opportunities to evaluate understanding without relying on outside materials.
California General Building Contractors must obtain the appropriate Class B contractor license through the California Contractors State License Board (CSLB).
The general licensing process includes:
The included courses provide examination preparation. CSLB determines application eligibility, examination requirements, and license issuance.
California regulates general building contractors through Business and Professions Code Section 7057 and the Contractors State License Board.
The Class B General Building Contractor classification covers qualifying structures requiring the use of at least two unrelated building trades or crafts. This includes applicable residential and commercial construction activities.
General building contractors may coordinate appropriately licensed specialty subcontractors and perform construction work within the scope permitted by California licensing law.
Specific rules apply to framing and carpentry projects, single-trade work, and contracts involving specialty construction activities.
Applicants generally must demonstrate qualifying experience, submit the appropriate CSLB application, and complete the required examinations unless an applicable waiver or exemption applies.
Contractor licensing also involves bonding and other business responsibilities. Contractors must comply with applicable building codes, occupational safety standards, and the requirements of their authorized classification.
The courses are based on the following reference books (not included).
Please Note: No physical or digital reference books are included with this Business & Trade Online Courses package. Both courses provide organized examination preparation based on applicable reference materials and CSLB examination subjects.
Preparing for the California General Building (B) examination requires knowledge of building construction, project coordination, construction calculations, structural components, finish work, and safety practices.
Planning and Estimating: Review construction plans, specifications, project scope, material quantities, scheduling considerations, and estimating procedures.
Framing and Structural Components: Study floor framing, wall framing, roof construction, seismic hardware, siding, stucco, decks, and stairs.
Core Building Trades: Understand plumbing, electrical, HVAC, concrete construction, roofing, insulation, earthwork, surveying, and weatherproofing principles.
Finish Trades: Review drywall, plaster, painting, flooring, cabinetry, millwork, tile, stone, doors, windows, and finish installation practices.
Safety: Focus on personal protective equipment, construction hazards, transportation safety, traffic control, and environmental safety requirements.
The California Law and Business course provides additional preparation related to contractor business operations, contracts, financial management, employment responsibilities, and construction law.
Students can reinforce these subjects through online lessons, reading chapters, cram sheets, practice questions, and comprehensive final examinations.
The California Law and Business Exam Prep Online Course is included with this package.
In addition to technical construction knowledge, California contractor applicants must understand important business and legal responsibilities.
The CSLB Law and Business examination study guide identifies seven major examination categories:
The Law and Business Examination is closed book and uses multiple-choice questions. Its content complements the General Building trade course by addressing the responsibilities involved in operating a California contracting business.
Students can prepare for both examinations using the same four-layer study approach, reinforcing technical construction subjects alongside contractor business and legal requirements.
At 1 Exam Prep, we understand that California contractor licensing preparation involves both technical construction knowledge and important business responsibilities.
Our Business & Trade Online Courses organize these subjects into focused lessons designed to help students study systematically and develop stronger understanding.
Instructor-led videos introduce construction and business concepts. Reading chapters reinforce essential information, while cram sheets condense important details into convenient review materials.
Practice questions provide opportunities to apply knowledge, understand answer explanations, and identify subjects requiring additional attention.
The final review phase brings together key information through master cram sheets and full-length practice examinations, supporting comprehensive preparation across both courses.
Because California contractor examinations are closed book, our learning method emphasizes retaining information rather than depending on reference books during testing.
Build stronger construction knowledge, improve your understanding of California contractor business requirements, and prepare for both licensing examinations with 1 Exam Prep.
