Common Series 66 Mistakes

1. Under-studying Regulations

With 45% of the exam on laws/regulations, many candidates spend too little time here.

2. Confusing Registration Rules

Know the differences between:

• Federal vs. state registration
• Broker-dealer vs. investment adviser
• Agent vs. IAR

3. Missing Exemption Details

Exemptions are heavily tested. Know which securities and transactions are exempt.

4. Ignoring Ethics Scenarios

Many questions present ethical dilemmas. Know prohibited practices cold.

5. Assuming Series 7 Knowledge is Enough

The Series 66 has different emphasis. Don't skip products/investments review.

Series 66 Pass Strategies

• Administrator can issue stop orders for 10 business days
• Agents must pass exam within 2 years of application
• IAs must keep records for 5 years (first 2 in office)
• Consent to service of process lasts until revoked

4. Practice Scenario Questions

The exam presents many scenarios. Practice identifying:

• What registration is required?
• Is this an exempt security/transaction?
• Is this conduct prohibited?

5. Take Full Practice Exams

• Complete 3-5 full practice exams (100+ questions)
• Score 80%+ consistently before scheduling
• Review every wrong answer thoroughly

Series 66 Format and Scoring

The Series 66 has 110 items: 100 scored and 10 unscored pretest questions, with 150 minutes. NASAA's passing standard is at least 73 of the 100 scored questions correct, and the fee is $177. The SIE and the Series 7 are corequisites for registration, so you must pass both (in either order); the Series 66 itself has no prerequisite exam.

NASAA's outline weights the four sections 8%, 17%, 30% and 45%. Laws, Regulations and Guidelines is the largest section, so most of your study time should go there. Because the exam combines state registration and adviser content, plan to study both halves rather than skipping the one you find easier.

Retake Waits

NASAA's waits are 30 days after the first and second failures and 180 days after a third failure. For enrollment windows opened from January 4, 2027, NASAA reduces the 180-day wait to 60 days. Each retake costs the exam fee again, so use practice results to confirm readiness before you pay.

Which Exam Fits Your Plan

Choose the Series 63 if your registration is as a securities agent and you need state registration for securities sales. Choose the Series 65 if you plan to give investment advice for a fee as an investment adviser representative. Choose the Series 66 if you need both the agent and adviser content in one combined exam, and remember that the Series 66 has its own corequisite rules, so check them before you register.

A Study Plan Built from the Outline

Start with the outline weights, not with the chapter order of a book. Mark each topic you already use at work, then spend most of your time on the largest sections and the topics you have never seen. Use short mixed practice sets once you have covered each section, because the exam does not announce which topic each question tests.

Review every wrong answer. Write one sentence on why the correct answer is right and one on why the closest wrong answer fails. This habit does more for scaled exams than memorizing facts, because the questions test judgment in a scenario as well as recall. Finish with timed, full-length practice so the pace feels normal on exam day.

Confirm Current Details

Exam format, fees and retake rules change. Before you schedule, check the current exam page and candidate materials on the FINRA or NASAA site linked in this guide. Use this article as a study plan, not as the source of official rules.
