Start with the free sample
The 3 free questions (one each from sections II, III and IV) run in the same test player as the mocks, with a question palette, mark for review and a clock. Each mock is 100 questions with sections mixed, in 150 minutes. The real Series 66 also carries 10 unscored pretest questions in the same 150 minutes (110 in all), so its pace is a little faster than ours.

Each mock matches the real exam's number of scored questions in each of the four sections. State-law questions follow the version of the law NASAA's study guide says is tested: the Uniform Securities Act of 1956 as amended by NASAA, and NASAA's model rules as NASAA wrote them. Your own state may have adopted them with changes; the questions do not test state-by-state differences.
What you see after every mock
- Your score in each of the four sections, side by side, with your time per question in each, and a line naming your lowest-scoring section. (NASAA's study guide says candidates who fail are told their score in each of the four sections.)
- The reason behind every answer, naming the Uniform Securities Act section, the NASAA model rule or statement of policy, the federal rule or the finance concept it tests.
- A written report on the attempt, your pace through the mock, and your progress when you retake it.
A score here is the share of our questions you answered correctly. It is not a Series 66 score and does not predict one. On the real exam a pass is at least 73 of the 100 scored questions; treat 73% on these mocks as a planning line, nothing more.
The Series 66, as FINRA and NASAA describe it
- 110 multiple-choice questions: 100 scored and 10 unscored pretest questions, which are not identified.
- 150 minutes. To pass, at least 73 of the 100 scored questions must be answered correctly. The exam is closed book.
- There is no prerequisite, but FINRA says the Series 7 exam is a co-requisite; its page lists the corequisites as "SIE + S7TO". FINRA lists the cost as $177.
- NASAA's test specifications have been in effect since 12 June 2023.

About the Series 66 and this practice
The Series 66 is a NASAA (North American Securities Administrators Association) exam administered by FINRA. NASAA publishes a content outline and study guide; the study guide says its exam questions are NASAA's copyright and may not be used, copied, reproduced or republished without NASAA's prior written consent. Every question here is our own, written to that outline; none is a NASAA exam item.
Before you buy
If I score 73% here, will I pass?
We cannot say. Our questions are not NASAA's, and the real exam draws each form from its own pool. Use the section scores to see where you lose marks, then study those parts of the outline.
Which version of the law do the questions use?
The Uniform Securities Act of 1956 as amended by NASAA, which NASAA's study guide says is the version tested (not the 2002 Act), NASAA's model rules and statements of policy, and the federal statutes and SEC rules the study guide lists.
What do I get?
200 original questions in 2 mocks of 100, each with the official number of questions per section and a 150-minute clock, in the full test player with a question palette and mark for review. After each mock: your score and time per question by section, a written report, and the explanation for every answer. Retake either mock as often as you like.
How do I pay and get access?
One payment by card (or PayPal where offered), handled by our payment provider. In the United States the price is charged in US dollars; elsewhere in your own currency where we support it, otherwise in Indian rupees with the local figure shown as an estimate. Access opens on this device straight after payment. Sign in afterwards to keep it on your account. Purchase policy.
