How Hard Is the Series 24? Pass Rate & Study Plan

What the Series 24 Exam Is

The Series 24, formally the General Securities Principal Qualification Examination, is the FINRA license that authorizes you to supervise a broker-dealer's investment-banking and securities-business activities. Where a Series 7 lets you sell, the Series 24 makes you responsible for the people who sell and for the firm's compliance with securities rules. It is the credential that turns a registered representative into a principal.

Exam Format at a Glance

The Series 24 is a computer-based exam delivered through Prometric or online proctoring.

• Questions: 150 multiple-choice items.
• Time limit: 225 minutes (3 hours and 45 minutes).
• Passing score: 70%.
• Exam fee: $235.

At 150 questions in 225 minutes, you have roughly 90 seconds per question. That pace is comfortable if you know the material and punishing if you have to reason every answer from scratch, so the exam rewards recognition speed over deliberation.

What Passing Actually Requires

Because the passing score is 70%, you can miss up to roughly 45 of the 150 questions and still pass. That margin sounds generous, but the Series 24 draws from a broad supervisory syllabus — supervision of investment banking and underwriting, trading and market-making, brokerage-office operations, sales-practice compliance, financial responsibility, and recordkeeping. The breadth, not the depth of any single topic, is what trips candidates up.

Is the Series 24 Hard?

The Series 24 is widely regarded as one of the more demanding principal exams because it is a supervisory exam layered on top of representative-level knowledge. It assumes you already understand products and transactions and then asks whether you can oversee them: reviewing correspondence, approving accounts, monitoring trading, and enforcing written supervisory procedures. Many candidates find the rule-application scenarios harder than raw memorization, since a single question may combine a sales-practice rule with a supervisory obligation.

How to Prepare

• Budget real study time. Most candidates commit several weeks of focused study; the volume of supervisory rules makes cramming unreliable.
• Master the rules, not just the products. Focus on who must approve what, what must be documented, and which review is required before versus after a transaction.
• Drill scenario questions. Practice items that force you to apply a supervisory rule to a fact pattern, because that is the format that decides pass or fail.
• Use full-length timed practice. Rehearse at the 150-question, 225-minute pace so exam-day timing feels routine.

Cost and Prerequisites

The exam fee itself is $235, typically paid by your sponsoring firm. Beyond the fee, budget for a prep course or question bank, which is usually the larger expense. The Series 24 requires an appropriate representative-level prerequisite and firm sponsorship, so you generally pursue it while already employed at a FINRA member firm rather than as an independent candidate.

Career Value

The Series 24 is a gateway credential for supervisory and management roles inside broker-dealers. Holding it lets a firm designate you as a principal responsible for supervising general securities activities — a prerequisite for many branch manager, compliance, and supervisory positions. Because the license shifts you from a sales role to an oversight role, it is often the step that opens management tracks and compliance leadership. For professionals aiming at supervisory, compliance, or operations leadership at a broker-dealer, the Series 24 is frequently the single most important qualification after the Series 7.

Bottom Line

The Series 24 is a broad, rules-heavy supervisory exam: 150 questions, 225 minutes, a 70% bar, and a $235 fee. Treat it as a test of supervisory judgment rather than product trivia, prepare with timed scenario practice, and it becomes the credential that moves your career from selling securities to running the desk.
