California General Building (B) Contractor Licensing Exam Prep Business & Trade Online Courses

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.

Our Proven 4-Layer Study Method

Every tested subject gets the same four layers, in the order that makes the material stick:

  1. Subject Video — A focused, instructor-led lesson that walks you through the concepts, the terminology, and the traps the exam likes to set.
  2. Reading Chapter — A brief, plain-English (or Spanish) chapter that reinforces the video. No 400-page codebook to wade through — just what you need to know, explained clearly.
  3. Cram Sheet — The key facts, figures, and rules for that subject condensed onto a tight memory sheet you can review anywhere.
  4. Practice Questions — Exam-style questions for that subject, each with a full answer explanation, so you know not just what the right answer is but why.

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.

Then Lock It In

Once you’ve worked through every subject, the final phase pulls it all together:

  • Master Cram Sheets — Every subject’s cram sheet consolidated into one review set you can run through in the days before your exam.
  • Full-Length Final Exams — Unique practice finals built to mirror the real exam’s structure and subject weighting. Take them as many times as you need to walk in confident.

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.

Exam Details

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:

  • Planning and Estimating — 15%: Understanding project scope, code compliance, construction error identification, plans and specifications, field inspections, project coordination, and estimating materials, equipment, and labor.
  • Framing and Structural Components — 20%: Subfloor framing, wall framing, roof framing, seismic hardware, siding, stucco, decks, and stairs.
  • Core Trades — 30%: Plumbing, electrical systems, HVAC, concrete, earthwork, surveying, insulation, acoustical materials, weatherproofing, and roofing.
  • Finish Trades — 20%: Painting, staining, coatings, interior wall coverings, tile, stone, flooring, cabinetry, millwork, plaster, drywall, ceilings, windows, skylights, doors, and landscaping.
  • Safety — 15%: Personnel safety, transportation and traffic control, and environmental safety requirements.

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.

Closed Book Test

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.

Licensing Steps

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:

  1. Confirm Your Classification: Determine whether the Class B General Building Contractor classification matches the construction activities you intend to perform.
  2. Review Experience Requirements: Understand CSLB's qualifying construction experience requirements and how your work background supports your application.
  3. Prepare the Application: Complete the appropriate CSLB application for an original contractor license or another applicable licensing pathway.
  4. Submit Required Information: Provide qualifying experience documentation, application materials, and applicable fees.
  5. Prepare for Both Examinations: Study General Building (B) trade subjects and California Law and Business requirements using the two included online courses.
  6. Schedule Your Examinations: Follow the scheduling instructions issued through the CSLB application process.
  7. Complete Licensing Requirements: Satisfy applicable examination, bonding, insurance, fee, and license issuance requirements.

The included courses provide examination preparation. CSLB determines application eligibility, examination requirements, and license issuance.

State Requirements

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.
