IMPORTANT COURSE POLICIES & ACCESS DETAILS

Please review these technical requirements and scope details regarding your purchase:

  • Law & Business Exam Only: This course covers the universal California Law & Business portion of the examination only. Preparation for your specific trade technical exam (e.g., Class A, B, C-10, etc.) is sold separately.
  • Manual Restrictions: The digital eManual is optimized for offline reading on mobile or desktop devices, but it is read-only and cannot be printed.
  • Media Delivery: Audio lectures can be downloaded for on-the-go listening; video lectures are streaming-only.
  • Testing Portal: Online practice exams require an active internet connection and cannot be downloaded for offline use.

Master Each Section of the California Law & Business Exam

The Universal Rule

Every California contractor—whether a Class A General Engineering, C-36 Plumbing, or C-61 Limited Specialty applicant—must pass the exact same standardized Law & Business Exam. Construction laws, payroll taxes, mechanics liens, and Cal/OSHA rules apply identically across every single trade.

💡 Two Key Exceptions

  • Exam Waivers: If an applicant has passed the exam or served as a license qualifier in good standing within the past 5 years, the CSLB may waive the test entirely.

  • C-61 (D) Applicants: Because these niche trades do not have a practical trade test, these individuals only take the Law & Business Exam.

The Bottom Line: Because this requirement is completely universal, our study system is a high-value, mandatory asset for every single new contractor business entering the California market.
