Why This Chapter Matters

At 45% of the exam, this is the most heavily weighted section by far. Nearly half of all questions test your knowledge of securities laws, registration requirements, and ethical obligations. You cannot pass the Series 66 without mastering this material.

The exam tests the Uniform Securities Act (USA), federal securities laws, registration requirements for all four person types (IAs, IARs, BDs, agents), the Administrator's enforcement powers, and the ethical and fiduciary standards that govern the industry.


Exam Strategy

Focus on:

  • IA definition and three-prong test: The most frequently tested concept in the entire exam
  • Registration differences: IA (SEC or state) vs. BD (SEC + FINRA + state) - know the "OR" vs. "AND" distinction
  • Exemptions vs. exclusions: Different concepts with different consequences
  • Administrator powers: What requires notice/opportunity for hearing vs. what doesn't
  • Fiduciary duty: IAs owe a fiduciary duty; BDs follow Reg BI; know the difference
  • Prohibited practices: Sharing in client accounts, guarantees, churning, front-running
