Registered Options Principal Exam (Series 4) Study Guide

Before you build a study plan, lock in the exam's basic structure. The Series 4 (Registered Options Principal Exam) is a 125-question, multiple-choice exam administered under a 3 hour and 15 minute time limit.

• Questions: 125, all multiple choice
• Time limit: 3 hours and 15 minutes
• Passing score: 72%
• Exam fee: $200
• Governing body: FINRA
• Corequisites: SIE and Series 7

The exam has been in continuous use since April 1975, which tells you the underlying options-supervision framework it tests is stable and well-documented — there's no reason to chase rumors about a redesign. Because the Series 4 carries corequisites, you should already have passed (or be concurrently sitting for) the SIE and Series 7 before this one is on your calendar. Candidates must also be associated with and sponsored by a FINRA member firm (or another applicable self-regulatory organization member firm) to sit for the exam — this is not an open-enrollment test you can register for independently.

FINRA publishes an official content outline for the Series 4, broken into six functions, each with its own share of the 125 scored items. Knowing the weight of each function tells you where to invest your study hours.

• F1 — Supervise the Opening of New Options Accounts: 21 questions
• F2 — Supervise Options Account Activities: 25 questions
• F3 — Supervise General Options Trading: 30 questions
• F4 — Supervise Options Communications: 9 questions
• F5 — Implement Practices and Adhere to Regulatory Requirements: 12 questions
• F6 — Supervise Associated Persons and Personnel Management Activities: 28 questions

Those six functions sum to the full 125-item exam. Notice that F3 (general options trading supervision) and F6 (supervising associated persons) are the two heaviest functions — together they account for close to half the test. F2 is close behind. If your study time is limited, weighting your review toward F3, F6, and F2 mirrors how the exam itself is weighted, while F4's comparatively small share means communications-supervision topics deserve a lighter, but not zero, pass.

The Series 4 uses a straightforward pass/fail cut score: you need 72% correct across the 125 scored items to pass. FINRA does not publish a scaled-score breakdown by function for this exam, so treat the 72% threshold as the single number that matters on exam day — there is no partial credit for being close on any one domain.

If you don't clear that bar, FINRA's retake rules (which apply broadly to the SIE and the representative and principal exams under Rule 1220) set the waiting periods. After a first or second failed attempt, you must wait 15 calendar days before retaking the exam. If you fail three or more times in succession within a two-year period, the required wait jumps to 60 calendar days before you're permitted to try again.

Practically, this means a failed attempt is expensive in both money and time — you'll owe the exam fee again and lose at least two weeks of momentum. That's the strongest argument for treating your first sitting as the only sitting: build in enough practice-test repetition beforehand that 72% becomes a comfortable floor, not a stretch target.

The Series 4 is not a standalone credential you can pursue on your own initiative outside a firm. Two structural requirements shape when and how you sit for it.

• Sponsorship: candidates must be associated with and sponsored by a FINRA member firm, or another applicable self-regulatory organization member firm, to be eligible to register for the exam.
• Corequisites: the Series 4 has corequisite exam requirements — you must pass the SIE and Series 7 exams to actually hold the Registered Options Principal registration.

In practice, this usually means the Series 4 comes after, or is scheduled alongside, your representative-level registration path — firms typically sequence a new options principal candidate through the SIE and Series 7 first, then layer the Series 4 on top once that person is taking on supervisory responsibility for options accounts. If you're planning your own registration timeline, confirm with your firm's compliance or registration team exactly how they want the corequisites sequenced, since firms can differ on whether they require all three exams completed before you sit, or allow the Series 4 to be scheduled concurrently.

A well-structured Series 4 study plan mirrors the exam's own weighting rather than treating all six functions as equal. Since F3 (30 questions) and F6 (28 questions) together make up nearly half the exam, they should anchor your schedule — plan multiple review passes on general options-trading supervision and on supervising associated persons and personnel management before you move to lighter-weighted areas.

• Start with F3 and F6: the two largest functions, worth the most in raw point value.
• Follow with F2 (25 questions) and F1 (21 questions): account-activity and new-account-opening supervision, which build on similar underlying options concepts.
• Finish with F5 (12 questions) and F4 (9 questions): regulatory-requirement practices and communications supervision, the two smallest slices.

As a general test-taking principle, allocate your review time roughly in proportion to each function's question count, but don't skip the smaller functions entirely — a 9-question function like F4 is still worth real points, and principal-level supervisors are often tested on nuanced communications-review scenarios that reward careful, not extensive, preparation.

Full-length, timed practice tests are the single most reliable way to know where you actually stand against the 72% passing score before you spend the $200 fee on the real exam. Because the real Series 4 runs 125 questions in 3 hours and 15 minutes, your practice sessions should replicate that pace so you build a real sense of timing pressure rather than discovering it on exam day.

• Take at least one full-length, timed practice exam under real conditions before scheduling the actual test.
• Score each attempt by function, not just overall, so you can see whether your weak spots line up with the heavily-weighted F3 and F6 areas.
• Treat any practice score meaningfully below 72% as a signal to add another review pass on your lowest-scoring function before you book a date.
• Re-take practice tests spaced a few days apart rather than back-to-back, so you're measuring retention rather than short-term memorization.

Given the 15-day minimum wait on a failed attempt, a few extra days spent validating your readiness with practice tests is almost always cheaper than a failed sitting.
