Series 66 exam practice questions, Series 66 practice exams and Series 66 exam prep for the NASAA combined state law exam

The Series 66, formally the Uniform Combined State Law Examination, is written by the North American Securities Administrators Association and administered by FINRA at Prometric test centers. You get 110 multiple-choice questions in total: 100 that count toward your score and 10 unscored pretest items scattered through the exam without any marking. The time limit is 150 minutes, so you have about 82 seconds per question. Passing requires at least 73 of the 100 scored questions correct, which is 73%, a slightly higher bar than the Series 65 or Series 63. The fee is $177, paid to FINRA. The one structural thing that sets the Series 66 apart from the Series 65 is the co-requisite: you cannot use the Series 66 to register until you have also passed the Series 7. The order does not matter, so plenty of candidates sit the Series 7 first and the Series 66 a few weeks later.

• 100 scored questions plus 10 unscored pretest items, 110 total
• 150 minutes, roughly 82 seconds per question
• Pass with 73 of 100 correct, which is 73%
• Fee $177, and the Series 7 is a co-requisite

NASAA publishes a content outline that tells you exactly how the 100 scored questions are split, and the Series 66 leans much harder on law than the Series 65 does. Economic Factors and Business Information is 8% of the exam, about 8 questions. Investment Vehicle Characteristics is 17%, about 17 questions, on equities, fixed income, pooled products and derivatives. Client and Customer Investment Recommendations and Strategies is 30%, about 30 questions, covering client profiling, portfolio construction, tax and retirement considerations, and performance measurement. Laws, Regulations and Guidelines, including the prohibition on unethical business practices, is the single biggest area at 45%, about 45 questions. That 45% is the reason the Series 66 feels different: nearly half the exam is state and federal securities law and ethics, because the Series 66 absorbs the state-agent law that would otherwise be its own Series 63.

• Economic Factors and Business Information: 8%, about 8 questions
• Investment Vehicle Characteristics: 17%, about 17 questions
• Client and Customer Investment Recommendations and Strategies: 30%, about 30 questions
• Laws, Regulations and Guidelines: 45%, about 45 questions

This is the question that sends most people to this page, and the answer turns on one fact: are you taking the Series 7? The Series 66 has the Series 7 as a co-requisite, so it only makes sense if you are already at a broker-dealer or dually registered firm that is putting you through the Series 7 anyway. In that case the Series 66 is the efficient path: one exam and one $177 fee register you as both an agent and an adviser representative, instead of sitting the Series 63 and the Series 65 separately. If you are going independent, joining a registered investment adviser, or otherwise will not hold a Series 7, you cannot use the Series 66 at all, and the Series 65 is your exam because it stands alone with no co-requisite. The content overlaps heavily, but the Series 66 is shorter (100 scored questions versus 130) precisely because it assumes the product knowledge the Series 7 already tested.

• Take the Series 66 only if you are also taking the Series 7
• One exam, one $177 fee registers you as agent and adviser rep
• No Series 7 in your plan? Take the Series 65 instead, it stands alone
• The Series 66 is shorter because the Series 7 covers the products

NASAA does not publish official pass rates for the Series 66, so any specific figure you see comes from a prep provider's own student data rather than the regulator. Provider estimates commonly land in the 65% to 73% range for first-time candidates, and the exam is widely considered a notch tougher than the Series 63 because of that 45% law weighting and the higher 73% pass mark. For someone who has just passed the Series 7, the product material feels familiar and the work is concentrated in the law, ethics and adviser-specific rules. Most candidates study 20 to 40 hours over two to four weeks when the Series 7 is fresh, and more if it has been a while. The reliable predictor is not hours logged but how many exam-style questions on the Uniform Securities Act, fiduciary duty and prohibited practices you have worked and reviewed.

• NASAA publishes no official Series 66 pass rate
• Provider estimates run roughly 65% to 73% first time, unverified
• 20 to 40 hours over two to four weeks is common when the Series 7 is fresh
• The law and ethics 45% is where the exam is won or lost

If you fail, NASAA requires a minimum 30-day wait before your second attempt, another 30 days before your third, and a minimum of 180 days before a fourth attempt and every attempt after that. There is no lifetime cap. Passing the Series 66 starts the same two-year clock the other NASAA exams use: your credit is valid for two years, and if you do not register with a state inside that window the exam expires and you sit it again. Because the Series 7 is a co-requisite, your Series 66 credit is only usable once the Series 7 is also passed and active, so keep both current. NASAA's Exam Validity Extension Program can stretch the two-year window to five years if you enroll through your FinPro account, pay the annual fee and complete the continuing education, but only in states that have adopted the program.

• 30-day wait after a first or second failure, 180 days after a third
• No lifetime cap on Series 66 attempts
• Exam credit expires two years after passing if you never register
• The Series 7 co-requisite must be passed for the credit to be usable

The professional designation waivers that skip the Series 65 do not map cleanly onto the Series 66, because the Series 66 is a combined exam tied to the Series 7. States that grant waivers for the adviser portion generally point CFP, CFA, ChFC, PFS, CIC and now CIMA holders toward the standalone Series 65 route rather than the Series 66. In practice, if you qualify for a designation waiver you will usually take the Series 65 path, and the Series 66 is the exam you sit when you are going through the Series 7 at a broker-dealer and want a single combined registration. A waiver, where it applies, removes only the exam: you still file Form U4, clear a background check and pay your state fees, and acceptance varies by state, so confirm with your state securities administrator before you rely on it.

• Designation waivers generally point you to the Series 65, not the Series 66
• CFP, CFA, ChFC, PFS, CIC and CIMA are the qualifying designations
• A waiver skips the exam, not Form U4, the background check or state fees
• State acceptance varies, so confirm with your state administrator
