How to Choose the Right SIE Exam Prep — Without Overpaying
The SIE exam prep market is crowded, confusing, and expensive if you're not careful. Kaplan has been the default name in securities licensing for decades. Achievable has captured significant market share with aggressive pricing and a modern platform. And a handful of free options have emerged that are genuinely worth considering.
This guide compares every major option honestly — with real prices, real pros and cons, and a recommendation for every type of candidate. We have a horse in this race (you're on our site), so we've deliberately led with the paid options before making our case for the free alternative. Make your own call.
The SIE Exam: What You're Actually Preparing For
Before comparing prep courses, it helps to understand what the SIE actually tests. The exam has 75 scored questions (plus 5 unscored pilot questions) and requires a 70% passing score. The registration fee is $80. No firm sponsorship is required — anyone 18 or older can take it.
The exam covers four sections with very unequal weighting:
| Section | Weight | Questions | Topics |
|---|---|---|---|
| Knowledge of Capital Markets | 16% | ~12 | SEC, FINRA, MSRB, market structure, Fed policy, economic indicators, IPO process |
| Understanding Products and Their Risks | 44% | ~33 | Stocks, bonds, options, mutual funds, annuities, ETFs, DPPs, REITs, hedge funds, all risk types |
| Trading, Customer Accounts and Prohibited Activities | 31% | ~23 | Order types, settlement, account types, Reg T, AML, suitability, Reg BI, insider trading, churning |
| Overview of the Regulatory Framework | 9% | ~7 | Registration, continuing education, Form U4/U5, outside activities, gifts, political contributions |
The most important strategic insight: Products and Risks is almost half the exam. Whatever prep course you choose, you should be spending 40-50% of your study time on Section 2. The regulatory framework section (9%) is the smallest — don't let it eat disproportionate time.
Paid SIE Prep Options: Honest Assessments
Kaplan Financial Education — $199 to $599
Kaplan is the most recognizable name in FINRA licensing prep and has been for decades. Their SIE packages start at $199 for the self-study package and go up to $599 for the premium live instruction package. All packages include 5 months of access — extensions cost an additional $49.
What you get: A comprehensive textbook (the License Exam Manual), unit checkpoint exams, a QBank of practice questions, and at the higher tiers, on-demand or live video instruction. Their most recent packages also include an AI Tutor feature for personalized concept explanations.
Who it's right for: Candidates who learn best from a structured textbook, who want live instructor access, or who are required to use Kaplan by their employer. The Kaplan name carries weight in institutional settings.
The real limitations: Kaplan's practice questions are frequently cited as harder and more densely worded than the actual SIE exam, which can lead candidates to over-study or feel underprepared. The platform is functional but not modern — it was built for a textbook-first generation of test-taker. And at $199 for the entry-level package, you're paying a significant premium over alternatives that have matched or exceeded Kaplan's content quality.
Achievable — $99
Achievable has become the most talked-about SIE prep course for independent candidates. At $99, it costs roughly half of Kaplan's entry-level package and includes a pass guarantee — if you complete the course and fail the SIE, you get your money back.
What you get: A full online textbook written in plain English, 2,000+ practice questions, 35+ full-length practice exams, short explainer videos on key topics, and an adaptive learning engine that tracks your retention and adjusts your study queue to focus on your weakest areas.
Who it's right for: Self-motivated candidates who want the best value in paid prep. Achievable is particularly well-suited to candidates who don't have a finance background — the textbook is widely praised for explaining concepts clearly without assuming prior knowledge. The adaptive algorithm is genuinely useful for efficient study.
The real limitations: No live instruction option. If you want a human to explain a concept in real time, Achievable isn't built for that. The platform is mobile-friendly but the study experience is better on desktop for the full textbook.
Knopman Marks — $375+
Knopman Marks is the institutional quality standard — used extensively by large broker-dealers and investment banks for employee licensing. Their SIE prep starts at $375 for self-study and exceeds $800 for live course access.
What you get: The most rigorous, demanding practice material available for the SIE. Knopman's questions are notoriously harder than the actual exam, which means candidates who pass their practice exams are typically very well prepared for the real thing.
Who it's right for: Candidates whose firms are paying for their prep, or those who specifically want to be challenged and don't mind grinding through difficult material. If your employer gives you institutional access, it's excellent. If you're paying out of pocket, it's hard to justify over Achievable at $99.
The real limitations: Price, primarily. The material density can also be overwhelming for first-time test-takers — some candidates report scoring in the 50s and 60s on Knopman practice exams in their final preparation week before passing the real exam. That feedback gap can be demoralizing.
STC (Securities Training Corporation) — $99 to $249
STC has been a longtime competitor in securities licensing prep. Their SIE packages range from $99 to $249 depending on features. They offer a Greenlight Exam Simulator with adaptive technology, similar in concept to Achievable's approach.
Who it's right for: Candidates who want a mid-tier option with more structure than Achievable but less expense than Kaplan or Knopman. STC is a solid, workmanlike prep provider without distinctive strengths or weaknesses.
The Free Option — 2 Dollar Tests
We built 2 Dollar Tests specifically because we believed the SIE prep market was overcharging for content that doesn't need to cost $200+. Here's what we offer, and where we're honest about the limits.
Free SIE Course — 32 Lessons, No Account Required
Our free SIE course covers all four exam sections across 32 lessons. Every lesson includes:
- Core content written for understanding, not memorization
- Key concept callouts highlighting what the exam will actually test
- Exam tip blocks with specific question-answering strategies
- Common mistake warnings for the errors that kill candidates
- Interactive concept checks at the end of each lesson
- Interactive drag-and-drop sorter games for the most tested classification concepts (regulator jurisdictions, bond features, risk types, order types, U4 disclosure events)
No login. No credit card. No content gated behind a trial period. The full course is accessible at 2dollartests.com/courses/sie-course/.
Free Interactive Study Tools
Beyond the course, we offer standalone tools used by candidates who are supplementing other prep programs:
- SIE Cheat Sheet — the most commonly tested rules, thresholds, and definitions on one page
- SIE Math Formulas — current yield, dividend yield, options breakeven, split math
- SIE Regulations Guide — every key regulation with the specific numbers the exam tests
- Bond Yield Visualizer — the inverse price/yield relationship made visual and interactive
- Options Profit Calculator — calls, puts, breakeven, max gain/loss
- Margin Safety Simulator — Reg T, maintenance margin, margin calls
- Suitability Matchmaker — Reg BI suitability practice with investor scenarios
Practice Tests — $2 Each
Our SIE practice exams are not free — they cost $2 per test. This is where we make our case honestly: the practice test market is dominated by either expensive bundles ($50-100+ for a question bank) or low-quality free questions that don't reflect actual exam difficulty.
Our 11-exam suite ($22 total for all 11, or $2 individually) is specifically calibrated to SIE difficulty. The questions lean heavily scenario-based — presenting a client situation and asking what happens next — which is how FINRA actually writes the exam. At $2 per test, candidates can use our exams as a final readiness check alongside any primary prep program without a meaningful cost commitment.
Where Free Prep Has Limits
We're not going to pretend the free course replaces everything. Here's where paid prep has a genuine edge:
- Adaptive learning: Achievable's algorithm tracks your individual retention across 2,000+ questions. Our concept checks are good, but they don't dynamically adjust a study queue for you.
- Volume of practice questions: 2,000+ questions (Achievable) versus our focused 880-question practice exam bank. Quantity matters for candidates who want to drill extensively.
- Live instruction: If you want a human instructor, Kaplan is the only option. We don't offer that.
- Accountability structures: Paid courses often motivate completion simply because money is on the line. If you know you struggle with self-directed study, the $99 commitment to Achievable may be worth it for that reason alone.

The Honest Recommendation by Candidate Type
You're on a tight budget (or just don't want to spend money before you know you like this career)
Use our free course for primary prep. Work through all 32 lessons in order. Then buy 3-4 of our $2 practice tests in your final week. Total cost: $6-8. This is a realistic path to passing for a self-directed candidate.
You want the best value in paid prep
Achievable at $99 is the answer. The adaptive algorithm is genuinely useful, the question bank is large, and the pass guarantee eliminates the financial risk. It's the best all-in-one paid option for independent candidates.
You want to supplement whatever you're already using
Our free interactive tools are worth bookmarking regardless of your primary prep. The Bond Yield Visualizer and Suitability Matchmaker in particular cover concepts that text-based courses explain but don't help you internalize. They're built for candidates who understand the concept but aren't yet confident applying it in question format.
Your firm is paying and you want the gold standard
Knopman Marks for rigor if you have time. Kaplan's premium package if you want live instruction. Either works well when cost isn't a constraint.
You have no finance background at all
Start with our free course to build foundational understanding, then move to Achievable for practice question volume. The combination gives you conceptual depth (our course) and adaptive drilling (Achievable) without overlap. Total cost: $99.
One More Thing Worth Knowing
The SIE has a roughly 74% overall pass rate — which means roughly 1 in 4 candidates fails on their first attempt. The failure rate isn't evenly distributed: candidates who use structured prep and take realistic practice exams before their test date pass at much higher rates than those who rely on casual review.
The biggest predictor of failure isn't which course you used — it's whether you took enough realistic, timed practice exams before your test date. Make sure whatever prep you choose includes full-length, timed simulations, not just flashcards or untimed Q&A.
The SIE is a real exam that requires real preparation. But it's also very passable with the right structure — regardless of whether that structure costs you $0 or $200.
