How many questions is the Series 24?

The Series 24 has 150 questions with a time limit of 3 hours 45 minutes.

The Series 24, formally known as the General Securities Principal Exam, is a professional qualification administered by FINRA (Financial Industry Regulatory Authority) for individuals seeking to supervise and manage securities trading and brokerage operations. This exam is a critical credential for those pursuing principal-level roles within broker-dealer firms, where supervisory responsibilities and regulatory compliance are paramount.

Candidates taking the Series 24 are typically existing professionals in the securities industry who have already demonstrated foundational knowledge through prior qualifications and are advancing to positions of greater authority and responsibility. The exam reflects the heightened regulatory expectations placed on principals who oversee trading operations, ensure compliance with securities regulations, and manage supervisory functions within their firms.

The Series 24 is a comprehensive examination designed to assess the knowledge and competencies required of general securities principals. The exam spans multiple functional areas related to principal responsibilities and regulatory oversight.

Content and Structure

The examination consists of 150 questions distributed across different functional domains. Function 2 covers 45 questions, while Function 3 encompasses 32 questions, with the remaining questions distributed across other principal supervisory functions. Candidates must demonstrate proficiency across all tested domains, as the exam evaluates the full breadth of principal-level duties.

Prerequisites

Before attempting the Series 24, candidates must first pass the Securities Industry Essentials (SIE) exam, which contains 75 questions, as well as an appropriate representative-level qualification exam such as the Series 7. These prerequisite qualifications ensure that candidates bring foundational securities knowledge to their principal-level studies. The SIE exam remains valid for 4 years, providing candidates with a reasonable timeframe to complete subsequent qualifications.

Sponsorship and Enrollment

Enrollment for the Series 24 requires sponsorship by an eligible regulatory authority; self-enrollment is not available. Candidates associated with a broker-dealer typically have a Form U4 submitted by their firm to formally request the examination, establishing the necessary regulatory connection and employment verification.

Cost and registration

The Series 24 examination costs 235 USD. Candidates should plan their scheduling carefully, as rescheduling or cancelling within two business days of a scheduled appointment, or failing to appear, results in a fee equal to the full cost of the exam. Additionally, candidates should budget for prerequisite exams; the SIE exam costs 100 USD.

Exam format

The Series 24 is administered by Prometric, FINRA's test delivery vendor. The examination can be taken either at a local test center or online, offering flexibility in how and where candidates complete their qualification. The exam is 225 minutes in duration, providing ample time for candidates to work through the 150-question assessment. A passing score of 70 percent is required to successfully complete the qualification.

How hard is the Series 24?

The Series 24 General Securities Principal Exam is moderately challenging—it requires solid grasp of broker-dealer supervision, but candidates who pass prerequisite exams and study systematically typically succeed. You need to score 70 percent to pass, and the exam contains 150 questions delivered across 225 minutes, giving you roughly 90 seconds per item with room for review. The main difficulty spike comes from balancing breadth of regulatory knowledge with depth in compliance oversight and firm operations. For most candidates moving from a representative role, the Series 24 represents a meaningful step up in scope and accountability.

What Is the Series 24?

The Series 24 qualifies you as a General Securities Principal—a supervisory role overseeing most broker-dealer activities. Unlike representative licenses (Series 7, Series 6), the Series 24 focuses on the firm's supervisory systems, compliance policies, and risk management rather than client-facing sales. If you're moving into management or compliance, or if your firm requires principal-level oversight authority, the Series 24 opens that pathway. The exam is also called the Qualifications Exam for General Securities Principal. Supervisors holding this license bear responsibility for reviewing and approving customer transactions, supervising registered representatives, and ensuring the firm meets regulatory obligations.

Prerequisites and Enrollment

Before you can sit for the Series 24, you must clear two hurdles. First, candidates must pass the Securities Industry Essentials (SIE) exam and an appropriate representative-level qualification exam such as the Series 7 before taking the Series 24. The SIE is your foundation—it covers market structure, product knowledge, and core regulatory principles. The SIE consists of 75 scored questions and costs $100; a passing SIE result remains valid for 4 years, so you have a reasonable window to pursue the Series 24 if you pass early. Many candidates complete the SIE and Series 7 in the same year, then apply for the Series 24 within 12 to 24 months once they're ready to step into a principal role.

Second, enrollment requires sponsorship by an eligible regulatory authority; self-enrollment is not available for the Series 24. Your broker-dealer submits sponsorship, typically via Form U4, on your behalf. Once sponsored, FINRA posts a 120-day window in which the exam must be taken—this is your scheduling deadline, so plan ahead. The enrollment fee for the Series 24 itself is $235. Combined with the SIE fee, the total cost of regulatory exams required before Series 24 eligibility is modest; the bigger investment is your study time and effort.

Exam Structure and Content

The Series 24 tests two primary supervisory functions across 150 multiple-choice items. The exam spans 3 hours and 45 minutes, so time pressure is moderate if you know the material; rushing is the real risk. The content breaks into two major areas: Function 2 covers supervision of general broker-dealer operations—compliance systems, capital requirements, and supervisory oversight—and contains 45 items. Function 3 addresses supervision of retail and institutional customer-related activities, including sales practices, suitability rules, and customer protection requirements, with 32 items. The remaining questions test supporting regulatory knowledge woven across both functions. Topics within these functions span anti-money laundering (AML), know-your-customer (KYC) protocols, sales practice standards, order routing and execution, customer complaint handling, and registration procedures.

Scheduling and Administrative Requirements

Once enrolled, you schedule your exam appointment with Prometric, FINRA's test delivery vendor. You can test at a local test center or sit for the exam online—both options are available. The online proctored format has become common and eliminates travel logistics. If you need to reschedule or cancel, act early: you must do so a minimum of 10 business days in advance to avoid any fees. If you reschedule or cancel within two business days, or fail to appear, you'll pay a rescheduling or no-show fee equal to the full exam cost. This penalty structure is why confirming your exam date well in advance and blocking out adequate study time matters.

Passing the Exam

The passing threshold is 70 percent—you need to answer at least 105 of the 150 questions correctly. Most candidates find this attainable if they master core supervisory concepts: firm compliance programs, anti-money laundering (AML) procedures, supervision of sales practices, capital rules, and registration requirements. The exam emphasizes application over trivia. Expect scenarios testing your judgment on whether a firm's practice meets regulatory standards or whether a supervisor's action complies with FINRA rules. These scenario-based questions reward deeper understanding.

Study Timeline and Difficulty

The Series 24 typically requires 50 to 80 hours of focused study for candidates who've already passed the Series 7 or 6. If you're fresh from the Series 7, many concepts overlap—customer protection rules, suitability, and sales practice oversight thread through both exams. However, the Series 24 adds layers on compliance infrastructure and firm-level controls that representative-level exams don't emphasize. Most candidates allow 6 to 10 weeks for preparation, particularly if they're balancing study with full-time work. The difficulty lies not in memorizing isolated facts but in integrating supervision principles across complex regulatory scenarios.

Common Study Challenges

Candidates often struggle with three specific areas. First, the interconnection between AML rules, KYC requirements, and customer protection—each topic appears separately in the curriculum, but the exam blends them in scenario form. Second, understanding the supervisory escalation chain—when a compliance issue should be reported to a principal, when to FINRA, and when to external authorities. Third, the nuances of record-keeping and documentation, which seem tedious but carry significant weight in exam questions because regulators rely on these records to monitor the industry.

Bottom Line

The Series 24 sits at a moderate difficulty level—harder than representative exams because it demands supervisory judgment, but manageable for anyone who has already passed the Series 7 or equivalent and commits to structured study. The time allocation is fair, the passing score is standard across FINRA exams, and the prerequisites ensure you have foundational knowledge. Success comes down to mastering firm compliance, supervisory responsibilities, and regulatory application rather than raw memorization. If your broker-dealer is sponsoring you for this exam, treat it as a critical gate to career advancement.

How the Series 24 compares to related exams

The General Securities Principal Exam (Series 24) is a supervisory-level qualification. Unlike the exams that license you to sell securities, the Series 24 qualifies you to supervise the people who do — approving accounts, advertising, underwriting, and the day-to-day activities of a broker-dealer's investment banking and securities business. Because it sits at the top of the qualification ladder, it's most useful to compare it against the representative-level and foundational exams that typically come before it: the SIE, Series 6, Series 7, and Series 63.

This page compares the Series 24 with those related exams across scope, difficulty, intended audience, and prerequisites, so you can see where it fits in your career path.

At a glance

The Series 24 is a principal (supervisory) exam, while the others are representative or foundational exams. The Series 24 consists of 150 multiple-choice questions, must be completed in 225 minutes, requires a score of 70% to pass, and costs $235.

Scope

  • Series 24 (General Securities Principal): Supervision of a broker-dealer's securities business — including sales, trading, underwriting/investment banking, and compliance oversight. It is about managing and supervising registered persons, not about selling.
  • Series 7 (General Securities Representative): The broad license to sell nearly all types of securities products (stocks, bonds, options, packaged products) as a registered representative.
  • SIE (Securities Industry Essentials): A foundational, entry-level exam covering basic industry knowledge — product types, market structure, regulatory framework, and prohibited practices.
  • Series 63 (Uniform Securities Agent State Law): State-level (blue-sky) law and the Uniform Securities Act — registration, ethical practices, and state regulatory requirements.
  • Series 6 (Investment Company and Variable Contracts Products Representative): A limited representative license focused on mutual funds, variable annuities, and variable life insurance.

Who each is for

  • Series 24: Experienced registered persons moving into a supervisory or management role — branch managers, compliance officers, and principals responsible for oversight.
  • Series 7: Registered representatives who want to sell the full range of securities products.
  • SIE: Anyone entering the industry, including students and candidates who don't yet have a sponsoring firm.
  • Series 63: Representatives who need to be registered to transact business at the state level (commonly paired with the Series 6 or 7).
  • Series 6: Professionals selling packaged investment products, often alongside an insurance license.

Prerequisites and sequence

  • SIE: No prerequisites and no firm sponsorship required — usually the first exam a candidate takes.
  • Series 6 / Series 7: Require firm sponsorship and are typically paired with the SIE to complete the representative qualification.
  • Series 63: No formal prerequisite exam; commonly taken alongside a representative exam to complete state registration.
  • Series 24: Requires an appropriate representative-level qualification (such as the Series 7) as a prerequisite before you can register as a principal — reflecting that supervisors must first understand the business they oversee.

Difficulty

The Series 24 is generally regarded as one of the more challenging exams because it tests supervisory judgment and detailed regulatory knowledge across many business areas rather than product mechanics alone. The SIE is the most approachable as an entry-level exam; the Series 6 and Series 63 are narrower in scope; and the Series 7 is a broad, demanding representative exam that most candidates complete before attempting the Series 24.

Ways to prepare for the Series 24

Preparing for the General Securities Principal Exam (Series 24) is a significant undertaking. The exam covers supervision of a broker-dealer's investment banking and securities business — a broad, principal-level body of knowledge. A common early question is whether free study resources are enough, or whether a paid prep course or textbook is worth the investment. The honest answer is that it depends on your budget, your baseline familiarity with FINRA rules, and how much structure you need. This page compares your free and paid options and explains when each makes sense.

Because the Series 24 has a 70% passing score, a broad question bank, and a long testing window, most candidates benefit from disciplined practice regardless of which resources they choose. The goal below is to help you spend your money only where it actually moves your score.

Free study options

  • Official FINRA content outline. FINRA publishes the exam's content outline and specifications for free. This is the single most important free resource — it tells you exactly which topic areas are weighted most heavily, so you can allocate study time deliberately.
  • Primary source rules and regulatory notices. The actual FINRA rulebook, SEC releases, and MSRB rules are all freely available online. Since the Series 24 tests your ability to apply rules as a supervisor, reading the source text builds durable understanding that paraphrased summaries often miss.
  • Free sample and diagnostic questions. Many providers offer a limited set of free practice questions. These are useful for a quick self-assessment of where you stand before committing money.
  • Employer-provided materials. If your firm sponsors your registration, it may already license a prep course. Always check before buying anything yourself.

Paid prep (courses and books)

  • Commercial question banks. Large, exam-weighted question pools with rationales are the highest-value paid feature. Repeated timed practice against realistic items is the best predictor of readiness, and free question sets are rarely large enough to cover the full blueprint.
  • Structured video/reading courses. Paid courses sequence the material, explain difficult supervisory concepts, and keep you accountable to a schedule — valuable if you're studying while working full time.
  • Printed or digital textbooks. A single well-reviewed Series 24 study manual gives you an organized, blueprint-aligned reference without the ongoing cost of a full subscription.
  • Progress tracking and readiness metrics. Paid platforms often estimate your likelihood of passing based on performance, which helps you decide when to schedule the exam.

When each makes sense

Your situationRecommended approach
You already hold principal-level familiarity with FINRA supervision and just need a refresherFree content outline + primary sources + a small paid question bank
You're new to supervisory material or study best with structureA paid structured course or textbook, supplemented by free primary sources
Your firm sponsors youUse employer-provided materials first; add a paid question bank only if the included practice pool is thin
You're on a strict budgetFree outline and source rules for content mastery, plus the largest affordable question bank — spend on practice, not on lectures

The pattern that works for most candidates: learn the content from free primary sources and the official outline, then spend money specifically on a large, exam-weighted question bank. Practice volume, not lecture volume, is what closes the gap to a passing score.

Frequently asked questions

What is the Series 24 exam?

The Series 24 is FINRA's General Securities Principal Exam, the qualification test for supervisors at broker-dealers. Passing it lets you oversee activities like trading, market making, underwriting, and sales supervision. It is a management-level exam, so it assumes you already hold a representative-level registration.

How much does the Series 24 exam cost?

The Series 24 exam fee is $235. Your sponsoring firm typically schedules the exam and pays the fee on your behalf, though policies vary by employer. Fees can change, so confirm the current amount on FINRA's fee schedule before you enroll.

How many questions are on the Series 24, and how long do I have?

The Series 24 has 150 multiple-choice questions, and you get 3 hours and 45 minutes to finish. That works out to about a minute and a half per question, which is comfortable if you have practiced under timed conditions. The exam is delivered on a computer at a testing center or through online proctoring.

What score do I need to pass the Series 24?

You need a score of 70% to pass the Series 24. There is no penalty for guessing, so answer every question even if you are unsure. Aim to score comfortably above 70% on practice exams before you sit for the real thing.

How do I register for the Series 24, and who is eligible?

You must be sponsored by a FINRA member firm, which files a registration form on your behalf and opens your enrollment window. You cannot walk in and take the Series 24 on your own like the SIE. You will also need an appropriate representative-level registration as a prerequisite, so check FINRA's current registration requirements for your exact situation.

How long should you study for the Series 24?

Plan on roughly 50–80 hours of focused study for most candidates — typically spread over four to eight weeks. The exam runs 150 scored questions with a 70% passing score, and the supervision rules it tests are detail-heavy even for experienced registered representatives, so the upper end of that range is safer if you have been away from the rulebook for a while.

How hard is the Series 24 exam?

The Series 24 is generally regarded as one of the tougher FINRA principal exams because it tests supervisory judgment across a broker-dealer's entire business, not just factual recall. According to FINRA, you must work through 150 multiple-choice questions and score at least 70% to pass. The breadth of supervisory material is what most candidates find hardest, so plan for sustained, structured study rather than cramming.

What is the pass rate for the Series 24 exam?

FINRA does not publish an official pass rate for the Series 24, so any percentage you see elsewhere is an unofficial estimate. The grounded benchmark is the passing standard itself: according to FINRA, you need a score of 70% to pass. Rather than worrying about other candidates' results, aim to consistently exceed that 70% threshold on realistic practice exams before test day.

How many questions are on the Series 24, and how much time do I get?

According to FINRA, the Series 24 consists of 150 multiple-choice questions with a time limit of 3 hours and 45 minutes (225 minutes). That works out to an average of 90 seconds per question, which is generous enough that raw speed is rarely the main challenge. Still, take full-length timed practice exams to build the stamina a nearly four-hour sitting demands.

How should I study for the Series 24 exam?

Build your prep around the exam's structure: drill with realistic question banks, study supervisory rules in depth, and take full-length practice exams under the real 225-minute time limit. Aim to score comfortably above the 70% passing standard on several consecutive practice tests before scheduling the real exam. Because the test covers supervision of an entire broker-dealer, spread your study over weeks rather than days and target your weakest areas after each practice test.

Can I pass the Series 24 using only free resources?

It's possible, especially if you already have strong supervisory and regulatory experience. The free content outline plus the primary FINRA, SEC, and MSRB rules cover the actual tested material. The main limitation of a free-only approach is practice volume — free question sets are usually too small to simulate the full exam. If you go free-only, compensate by drilling the source rules hard and testing yourself repeatedly. Since the passing score is 70%, you'll want consistent practice-test results comfortably above that before scheduling.

Is a paid course worth it for the Series 24?

A paid course is most worth it if you're newer to broker-dealer supervision, prefer guided structure, or are studying around a full-time job. The highest-value paid feature is a large, exam-weighted question bank with answer rationales — that's where paid options clearly beat free ones. Video lectures and readings are helpful but more of a convenience. If your budget is limited, prioritize spending on practice questions over lecture content.

How much should I budget for Series 24 prep beyond the exam fee?

The exam itself costs $235, and that's a fixed FINRA cost separate from any study materials. Beyond that, prep spending varies widely: you can study for essentially nothing using the free content outline and primary sources, or invest in a paid course or textbook. A reasonable middle path is to keep content study free and pay only for a quality question bank, which is typically the most cost-effective paid purchase for this exam.
