Overview Of The Series 66 Exam

The Series 66 (Uniform Combined State Law) Examination certifies individuals to act as qualified investment adviser representatives or securities agents. The exam covers topics directly related to client investment advice and placing securities transactions.

The exam was most recently updated in January 2019, following the tax law changes passed in 2018. The Series 66 is a co-requisite of the Series 7 exam, and both must be passed in order to register in a given state. You can find our list of the Best Series 7 Study Guides for resources you can use to help pass that test as well.

We’ll cover the Series 66 Exam in detail, and give you our picks for the best Series 66 study guides, review guides, and flashcards below, but if you just can’t wait, here’s the short list:

Series 66 Exam Details

The Series 66 Exam is made up of 100 multiple choice questions, which you’ll have 2.5 hours to answer.

You’ll be provided with a 4 function calculator and note taking materials when you sit for the exam. You’ll also need a government issued photo ID. No personal items are allowed inside the test room, so be sure to leave your cellphones, and other items somewhere safe.

The 4 main topics which make up the full Series 66 Exam. They cover the broad list of activities undertaken by investment advisors.

  • Economic Factors and Business Information (5% of questions)

There are no penalties for incorrect answers, so you should take an educated guess on any question you’re not sure about.
