What Is the Series 66 Exam?

The Series 66 exam is administered by the Financial Industry Regulatory Authority (FINRA) to broker-dealer representatives to qualify them as securities agents and investment adviser representatives. 

There are 100 multiple-choice questions on the exam; you have 150 minutes to take it and must score at least 73%. The co-requisite of the Series 66 exam is the Series 7 Top-Off exam, so you will need to pass both before you can apply to register in a state. 

How Much Do Series 66 Exam Prep Courses Cost?

Series 66 exam prep course prices differ between each course provider but usually start at $140 and approach $300. However, there are options outside of this range. Lower-cost courses are often self-study only, and higher-cost packages often include a live component. 

If you need to hire a tutor, you can expect to spend around $100 per hour. Aside from your study materials, the cost of the exam itself is $177, paid directly to FINRA, often by your broker-dealer.

Are Series 66 Prep Exam Prep Courses Worth It?

The Series 66 covers state law, which can help you understand what you should and shouldn’t do as an advisor. Material on the exam is notoriously dry and full of legalese. Even if you have a legal background or already work in the securities industry, you won’t pass the exam without studying for it. 

Most importantly, having a Series 66 designation can go a long way towards improving your job prospects in the securities industry.

How Many Hours Should You Study for a Series 66 Exam?

The amount of time required for you to study and pass your Series 66 exam depends heavily on your ability to grasp the information, as well as your background in the industry. However, you can expect to spend between 50 and 100 hours of study. Some exam prep courses also have built-in tools to automatically adjust what you’re learning based on how well you know the material. 

How Hard Is It To Pass the Series 66 Exam?

Some broker-dealers require their employees to sit for the Series 7 first, as it’s the harder of the two, but you should not underestimate the Series 66. It is not an easy test, and it’s not uncommon for people to take it lightly and fail on the first try after facing the Series 7. 

The Series 66 is the equivalent to passing both the Series 63 and Series 65, which are both easier than the Series 7 but still challenging. You can expect the material on the Series 66 to be drier than the Series 7, even though the Series 7 is more difficult of the two.   


We evaluated 23 different Series 66 exam prep courses and narrowed them down to the best options based on company reputation, pass rates, course flexibility, and cost. Also weighing heavily in our rankings were customer reviews and quality of training.

Each of our picks also offers self-study options, reasonable price points, and an excellent reputation for helping students pass their Series 66 on their first try. Some of our picks also provide pass guarantees.
