Is there a free Series 24 exam prep?
Yes. The full CertFuel Series 24 course is free through the end of 2026: a 22,000+ question adaptive bank, unlimited practice exams, section videos, per-unit audio podcasts, 3,100+ flashcards, and the Aiden AI tutor, with no credit card required. Outside the course, CertFuel also hosts a full-length Series 24 practice exam and a guide to what the Series 24 actually tests that need no account at all. Kaplan, STC, and Pass Perfect publish small free samplers or a demo lesson, but their full systems are paid.
What's the cheapest Series 24 exam prep?
CertFuel, which is free through the end of 2026. Among the paid options, Kaplan has the lowest entry price of the three legacy providers: its Basic Self-Study package is $259. STC Standard is next at $335, and Pass Perfect starts at $390 for its eBook-and-test-bank tier. All three are static, non-adaptive question banks, and none publish an exact question count.
Which Series 24 prep has the most practice questions?
CertFuel publishes a 22,000+ question adaptive bank. Kaplan, STC, and Pass Perfect do not publish exact question counts on their Series 24 product pages; STC's page separately advertises 700+ flashcards as an add-on product, which is a study aid, not a question-bank size. The Series 24 spans five supervisory domains (registration, general BD supervision, customer activity, trading, and investment banking), so a deep, topic-weighted bank matters more here than it does on a narrow single-topic exam.
Is the cheapest Series 24 prep good enough to pass?
It can be, especially for candidates who already supervised informally before sitting for the exam. The Series 24 has 150 scored questions (160 total with pretest), a 70% passing score, and 225 minutes to finish, covering nearly every function of a broker-dealer. Kaplan's $259 Basic tier gets you the SecuritiesPro QBank, License Exam Manual, a practice exam, and a performance tracker, but no instructor access or mastery exam. CertFuel costs nothing through the end of 2026 and adds an adaptive engine, unlimited practice exams, and 3,100+ flashcards on top of that.
Which Series 24 prep has adaptive learning?
CertFuel is the only provider in this comparison with a genuine adaptive engine that adjusts the questions you see based on your performance. Kaplan, STC, and Pass Perfect all build their Series 24 banks by topic or difficulty tier rather than adjusting to an individual candidate's weak spots. Separate from its adaptive engine, CertFuel also ships a lesson-aware AI tutor, Aiden, that explains any lesson and works examples on demand.
Do I need a paid Series 24 course?
No required course exists, and FINRA does not endorse any provider. Because the Series 24 requires firm sponsorship through Form U4, most candidates take it while employed, and many firms reimburse a specific provider (often Kaplan or STC, given their long-running enterprise contracts). If your firm covers one, use it. If you are covering the cost yourself, the CertFuel course is free through the end of 2026, which is less than any paid tier on this page.
How long does Series 24 prep take?
Most candidates prepare for the Series 24 in 4 to 8 weeks of consistent study, depending on how much hands-on supervisory or compliance experience they already have. The exam itself is 150 scored questions (160 total with pretest) in 225 minutes. For a closer look at what to expect on exam day, see our guide to the Series 24 pass rate.
