Best SIE Prep of 2026: Courses, Question Banks & Books Compared

Six SIE prep options compared with prices verified on each provider's own site — Achievable, Kaplan, STC, Knopman Marks, the Kaplan License Exam Manual, and FINRA's free practice test — plus which guarantee actually pays out if you fail.

Prices and product details verified June 12, 2026. Providers change pricing and bundles often — always confirm on the seller's site before you buy.

The SIE is the front door to the securities industry — no firm sponsorship required, results valid four years — and its prep market runs from a free official practice test to $895 white-glove programs. Since January 2026 every attempt costs a $100 exam fee, which quietly changes the math: a guarantee-backed course that prevents one retake pays for itself. Here’s how the market actually compares in 2026, with every price verified on the provider’s own site this month.

How we picked

We weighted three things: practice volume per dollar (full-length exams and question depth you’ll actually use), guarantee strength (a money-back refund beats extended access, and several big names offer nothing at all), and honest access terms (a cheap course on a 5-month clock can cost more than a pricier one you keep for a year). We earn a commission on some links — it never changes the order of these picks, and several picks here pay us nothing.

Two corrections to stale advice you’ll still find elsewhere: Solomon Exam Prep no longer exists — it merged into Pass Perfect under their shared owner CeriFi, so any list still recommending Solomon is out of date. And the exam itself changed shape: the current FINRA outline runs 80 items (75 scored plus 5 unscored pretest), not the 85 older guides describe, and the fee is now $100, up from $80 at the start of 2026.

Which one should you buy?

Also considered

Pass Perfect (listed from about $219 at review) absorbed Solomon Exam Prep and carries a genuinely strong “Pass Promise” — a full refund or free continued access until you pass, your choice — but full tier pricing only appears at checkout, which makes it hard to comparison-shop confidently mid-rebrand. ExamFX ($129–$249) looks like a bargain next to its “pass guarantee” banner, but the guarantee covers ExamFX’s insurance courses only — it does not apply to the SIE — and access windows run a short 90–180 days. Securities Institute of America ($139 with a refund-backed GreenLight guarantee) is a credible budget alternative, but its materials were still branded “2025 Edition” at review. TestGeek ($129, lifetime access) offers only about 5½ hours of video — too thin for an exam this regulation-heavy.

1. Achievable SIE

Top pick

Best for: The most course per dollar, with the simplest money-back guarantee

Online course + practice exams · $99 one-time, one year of access

Achievable packs a full online textbook, 2,000+ chapter quizzes with adaptive review, 35+ full-length practice exams, and bonus videos into a one-time $99 purchase with a year of access — and backs it with the cleanest guarantee in the market: pass any of its full-length practice exams in standard time, fail the real SIE anyway, and you get your money back. There are no live classes at any price, but as a self-study engine nothing matches its price-to-volume ratio.

Pros

  • Cheapest serious full course on the market, and it's one-time, not a subscription
  • Genuine money-back pass guarantee with one simple condition
  • 35+ full-length practice exams — more than competitors charging triple

Cons

  • No live instruction or instructor hotline at any tier
  • Text-first platform — the videos are a bonus, not a lecture course

2. Kaplan SIE Prep

Biggest brand

Best for: Scheduled, instructor-led classes from the most recognizable name in licensing

Live or on-demand course + book + question bank · Packages from $99; Premium OnDemand $199 / Premium Live Online $229 (5 months)

Kaplan's SIE packages now run $99 to $229 — far below what older reviews quote — and the Premium tiers buy real structure: instructor-led classes (live online or on-demand), the License Exam Manual, the SecuritiesPro QBank, an AI tutor, and a ladder of checkpoint and mastery exams. The catch is the calendar: access lasts 5 months (a $49 extension adds five more), and unlike most rivals here, Kaplan offers no pass guarantee on its securities courses.

Pros

  • Real scheduled classes with instructor access, at a price that now undercuts boutique rivals
  • Complete ecosystem — manual, question bank, and a structured exam ladder in one buy
  • À-la-carte store if you only need pieces (QBank alone is $49)

Cons

  • Shortest access window of the major providers: 5 months, then $49 to extend
  • No pass guarantee on securities exams

3. STC SIE Premier

Best guarantee + hotline

Best for: Instructor support on a budget, with a real refund if you fail

Online course + printed manuals + live classes (top tier) · E-Course $129 / Premier $141 / Premier Plus $293 — 6 months (current prices look promotional)

STC's Premier package bundles printed manuals, about 21 hours of on-demand lectures, 1,800+ flashcards, and — unusually at this price — an instructor hotline on every tier. Its pass guarantee is a true course-price refund, with homework attached: complete the progress exams, average 75%+ on the finals, and post a 75%+ 'green light' exam before test day. At review, prices sat well below STC's historical norms, so treat them as promotional and check before buying.

Pros

  • Money-back pass guarantee (Premier and up) — a refund, not just extended access
  • Instructor hotline included even on the cheapest tier
  • Premier Plus at $293 is the cheapest live-class option that also carries a money-back guarantee

Cons

  • The guarantee's three completion conditions are real homework
  • 6-month access with no cheap advertised extension

4. Knopman Marks SIE (Gold)

Premium pick

Best for: The high-touch program Wall Street firms run their own new hires through

Course + physical book + faculty access · Gold $265 / Platinum $495 / Diamond $895 — one-year access

Knopman Marks is the prep program many investment banks buy for their incoming analyst classes, sold retail: Gold includes a physical and digital textbook, video lectures, flashcards, customizable practice questions, and — even at the base tier — a private strategy call with the faculty. Platinum adds unlimited live review sessions and blended classes. It's the most polished, most expensive mainstream option, and it publishes a 50–70-hour study recommendation that's become the de-facto industry estimate.

Pros

  • Corporate-training pedigree — the same program big firms put new hires through
  • Longest access of the class-based providers (a full year)
  • Private faculty strategy call included at every tier

Cons

  • Highest entry price of the mainstream picks
  • No advertised money-back guarantee, and practice-question counts aren't disclosed

5. Kaplan SIE License Exam Manual (4th ed.)

Best book

Best for: Book-first studiers who want the canonical printed text behind their drilling

Book · $45 direct from Kaplan; Amazon third-party prices fluctuate

The standard reference text for the SIE — the same manual Kaplan bundles inside its $99–$229 packages, sold alone for $45 (an audiobook edition costs the same). It pairs naturally with free question drilling, or with Kaplan's $49 QBank for exam-style reps. One honest note: Amazon's third-party offers often run above Kaplan's own $45 direct price, so compare before you click buy. On a tighter budget, the brand-new SIE Exam 2027/2028 For Dummies ($31.99, published June 2026) bundles four online practice tests with the book.

Pros

  • The de-facto standard SIE text, current at the 4th edition
  • No subscription clock — study at your own pace
  • Audiobook edition for commutes

Cons

  • A book alone gives you no adaptive practice, analytics, or timed exams
  • Often cheaper bought direct from Kaplan than on Amazon

6. FINRA's Official SIE Practice Test

Best free

Best for: A difficulty check written by the people who write the exam

Online practice test · Free

FINRA itself publishes a free 75-question SIE practice test — questions similar to the real exam's, with feedback at the end on what you know and what needs review. It's one static, untimed form, so it won't build your knowledge or rehearse your pacing, but as a calibration tool it's untouchable: this is the only practice material written by the exam's administrator. Take it once early as a baseline and once late as a readiness check.

Pros

  • Written by the exam maker — the most honest difficulty calibration available
  • Completely free
  • End-of-test feedback shows what to review

Cons

  • One static form — no question-bank depth
  • Untimed, so it won't rehearse the 1h45m pacing

Start free, right here

Whatever you buy (or don't), PlayPrepHQ's FINRA SIE prep is free: exam-style quizzes, spaced-repetition flashcards, and a timed mock exam built to the real test blueprint. It pairs well with any of the paid options above — and it's a no-risk way to find your weak areas before spending anything.

Frequently asked questions

Is the SIE worth taking before getting hired?
Yes — the SIE is the rare FINRA exam with no firm sponsorship required: it's open to anyone 18 or older, and a pass stays valid for four years. Passing it as a student or career-changer signals commitment to recruiters and lets a firm move you straight to your top-off exam (like the Series 7) once hired. The training firms banks hire for their own new-hire classes build their programs around exactly this sequence.
Is FINRA's free practice test enough to pass?
It's the best free diagnostic available — 75 questions written by the exam's own administrator with feedback at the end — but it's one untimed form, so it can't give you question-bank depth or pacing practice. Use it to baseline your starting point and to calibrate real difficulty, do your repetitions with free drilling (like PlayPrepHQ's SIE quizzes and mock exam) plus a question-bank course, then re-check against an official-style exam before booking.
How hard is the SIE, and how long should I study?
Plan on roughly 50–70 hours — that's the published recommendation from Knopman Marks, the firm that trains many banks' new-hire classes. You need a 70 on 75 scored questions in 1 hour 45 minutes. FINRA doesn't publish an official pass rate; industry figures put it roughly between 70% and 74%, which fits the exam's reputation: most prepared candidates pass, but the heavily weighted regulation content punishes anyone who only skims.
Does SIE prep also cover the Series 7?
No — the SIE covers industry essentials, and the Series 7 is a separate, harder top-off exam that requires firm sponsorship. If you already have an offer in hand, most of the classroom providers sell the pair as a bundle (STC's SIE + Series 7 packages start at $372), which runs cheaper than buying the two courses separately.
How much does the SIE cost all-in?
The exam fee is $100 — it rose from $80 on January 1, 2026, and FINRA's fee schedule holds it at $100 through 2029 — and you pay it again for every retake, with a 30-day wait after each of your first two fails and 180 days after a third. Prep on top of that ranges from $0 (FINRA's practice test plus free drilling here) to about $99–$265 for a solid course, or $32–$45 for a book.
Do the pass guarantees actually pay out if I fail?
Read the fine print — they differ sharply. Achievable refunds your $99 if you passed at least one of its full-length practice exams before failing the real thing. STC refunds the course price on Premier and up, but only after you've completed its progress-exam ladder with qualifying scores. Pass Perfect's Pass Promise gives a full refund or free continued access, your choice. Kaplan and ExamFX offer no SIE pass guarantee at all — ExamFX's advertised guarantee covers its insurance courses only.
