Frequently Asked Questions

What is the Series 66 exam?

The Series 66 combines the Series 63 (state agent law) and Series 65 (investment adviser law) into one exam. It's often called the 'Combined State Law Exam' and is the most efficient path for dual registration.

What is the Series 66 pass rate?

The Series 66 exam has an estimated pass rate of 70-75% for first-time test-takers. The exam is heavily weighted toward regulations (45% of questions), so mastering the Uniform Securities Act and Investment Advisers Act is critical for success.

Do I need Series 7 before Series 66?

Yes. You must pass the Series 7 (or Series 62) before or concurrently with the Series 66. The Series 66 is designed as a 'top-off' exam for those who already have a FINRA representative-level license.

How many questions are on the Series 66?

The Series 66 has 100 scored questions plus 10 pretest questions. You have 2 hours 30 minutes and need 73% (73 correct answers) to pass.

Is Series 66 harder than Series 63 and 65 combined?

The Series 66 is generally considered similar in difficulty to taking both separately, but it's more efficient since you only take one exam instead of two. The content heavily overlaps with what's in Series 63 and 65.

How long should I study for Series 66?

Plan for 40-60 hours of study over 3-5 weeks after passing Series 7. Focus heavily on regulations (45% of exam) and client recommendations (30%). Complete at least 400 practice questions and score 80%+ before scheduling.
