How many questions is the Series 66 exam?

The Series 66 exam has 110 multiple choice questions, of which 100 are scored and 10 are unscored pretest questions that do not count toward your result. You have 150 minutes to finish. Because you cannot tell which ten are the pretest items, you answer all 110 as if they count, so building a full-length mock from your own notes is a good way to rehearse that length and the 150-minute pace.

What is the passing score for the Series 66?

You need to answer at least 73 of the 100 scored questions correctly to pass the Series 66, which is 73 percent. The 10 pretest questions do not affect your score. Most candidates aim to score comfortably above 73 on their practice mocks before scheduling the real exam, because the biggest section, laws and regulations, alone can swing you past or under that line.

Do I need the Series 7 for the Series 66?

Yes. The Series 7 is the co-requisite for the Series 66, and you must pass both to register as a securities agent and investment adviser representative. There is no required order between the two. The SIE is not required for the Series 66 itself, but it is required for the Series 7, so in practice most candidates complete the SIE and Series 7, then sit the Series 66.

Is the Series 66 harder than the Series 63?

Most candidates find the Series 66 harder than the Series 63. The Series 63 is 60 scored questions on state law alone, while the Series 66 is 100 scored questions that add investment adviser rules, economic factors, investment vehicles and client recommendations on top of the law. The 66 combines the material of the Series 63 and Series 65, so it covers more ground and rewards applying the rules to client scenarios rather than plain recall.

How long is the Series 66 exam?

The Series 66 exam is 150 minutes, or 2 hours 30 minutes, for all 110 questions. That works out to roughly 82 seconds per question, so pacing matters. Sitting timed mocks built from your own notes is the best way to train that pace, since the longer scenario questions in the client recommendations and laws sections can eat into your time if you are not used to them.

What is the difference between the Series 65 and Series 66?

The Series 65 qualifies you only as an investment adviser representative and has no co-requisite, so people who give advice for a fee but do not sell securities often take it on its own. The Series 66 qualifies you as both an investment adviser representative and a securities agent, but it requires the Series 7 co-requisite. If you already hold or are pursuing the Series 7, the 66 is usually the more efficient route to both registrations.

What does a Series 66 license allow you to do?

Passing the Series 66, together with the Series 7, lets you register in a state as both a securities agent, who can transact in securities for clients, and an investment adviser representative, who can give investment advice for a fee. It combines the state-law coverage of the Series 63 with the investment adviser material of the Series 65, so it is the common single-exam path for representatives who do both jobs.

Is this an official Series 66 practice exam?

No. PDFQuiz is an independent study tool and is not affiliated with or endorsed by NASAA or FINRA. This tool generates practice questions from the study material you upload so you can rehearse recall and reasoning between full mock exams, and it does not reproduce official exam questions, so use it alongside your prep course and the official NASAA content outline, not as a replacement for them.

What a Series 66 practice question generator does

Drill your own prep notes, not a bank you have memorized

The Series 66 rewards applying the rules to a client situation rather than rote recall, and by your second pass through a question dump you start remembering the answer letter instead of reasoning through the rule. You read a question on a prohibited business practice, the brochure rule or a suitable recommendation and you recall the option, not the logic. This tool flips the source. You upload what you are actually studying, your prep book, a study guide PDF or your own summaries, and the AI test question generator writes brand-new items from that text. Weak answers point straight back at the section you need to review, and a fresh practice set is always one upload away.

Works with any prep material and your notes

Upload your prep book, a study guide, the NASAA content outline, a glossary of terms or handwritten pages you photographed. If the file explains a Series 66 rule, definition or strategy, the generator can build questions on it.

Section-by-section drills

Shaky on laws and regulations one week and client recommendations the next? Upload only the notes for that section, then narrow to a single topic, like the brochure rule or portfolio strategy, when your scores are soft.

Fresh mocks every session

Generate a new set every time so you are testing knowledge, not recognition. Repeated retrieval on unseen items is what makes the rules and strategies hold up under the 150-minute pace of the real exam.

Series 66 sections and how to practice each one

The NASAA content outline splits the 100 scored questions across four sections. Upload the notes for whichever section you are covering and generate questions on it.

Section	Weight	Scored questions
Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices	45%	45
Client and Customer Investment Recommendations and Strategies	30%	30
Investment Vehicle Characteristics	17%	17
Economic Factors and Business Information	8%	8

Laws, regulations and prohibited practices is the single largest section at 45 percent, and client investment recommendations and strategies is next at 30 percent, so together they make up three quarters of the scored exam. Generating scenario-style questions from your own notes on the brochure rule, custody, suitability and portfolio strategy is the closest low-cost rehearsal for the applied questions the Series 66 rewards.

Simple process

How to make Series 66 practice questions in 4 steps

1 Upload your material: Drop in your prep book, a study guide PDF, the NASAA content outline or your own notes. Scanned and handwritten pages are read with OCR.
2 Set the drill: Pick the question count and difficulty. Run a 20 question warm-up on a lunch break or a full 100-question mock under the 150-minute limit.
3 AI writes questions: The AI reads your content and writes exam-style multiple choice questions with an answer key and explanations.
4 Review and repeat: Score the set, review the rule behind every miss, then generate a fresh drill on just those weak sections and go again.

Who uses this to prep for the Series 66

Advisers adding IAR registration

You already hold or are finishing the Series 7 and need the 66 to register as an investment adviser representative. Upload one section at a time and generate a quick set you can finish between client meetings, then hit the same weak area tomorrow with different questions.

Prep-course students

If you have already worked through the sample questions in your prep course once, you are drilling your memory of them, not the rules. Turn your prep book and notes into questions you have never seen, without buying a second exam simulator just to get fresh items.

Retakers targeting one weak section

When you came up short on laws and regulations or client recommendations last time, you do not need to redo everything. Upload just those notes, drill until the misses stop, and turn the section that was dragging your score under 73 into one you can answer on reflex.
