Free SIE Practice Tests: Every Full-Length Option Compared

What does the real SIE exam look like?

You’re studying toward a 75-scored-question, 5-pretest-question, 80-item exam. You get 105 minutes, you need 70% to pass, and the registration fee is $80. The questions are scenario-based and weighted to FINRA’s content outline:

A “real” practice test should match those weights, run somewhere near 75 questions, and use scenario-style items. Anything 25-and-under or evenly distributed across sections is a sampler, not a practice test.

Where can I take a free full-length SIE practice test?

The honest landscape:

So the question is not “where do I find one?” The question is which one is worth your time, and in what order.

How does the CertFuel free SIE practice exam compare?

The CertFuel SIE practice exam is a single page with 80 questions in a fixed order. Each question:

• Has four choices, one correct.
• Locks in your answer when you click and reveals the explanation. You cannot change a locked answer, the same way the real exam works.
• Shows the percentage of past CertFuel users who got it right, so you can see which items are objectively hard versus the ones you happen to miss.
• Is tagged with the FINRA outline topic and subtopic so you can spot patterns.

What’s different from the others:

• 80 items, not 75. Matches the real 75 + 5 pretest format.
• Per-question pass rate. None of FINRA, Achievable, STC, or Knopman shows you crowd accuracy on individual items. That’s the single most useful diagnostic for “is this a real-exam-style trap or a me problem?”
• No signup, no email. Most free vendor exams gate behind an email at minimum.
• Updated to current rules. Post-T+1, post-Reg BI.

The trade-off: it’s a study-mode exam (immediate feedback), not a timed simulation. For timed, end-of-exam-scored full-length practice, the CertFuel app generates unlimited fresh, exam-weighted practice exams from a 4,000+ question bank, scores you by section, and tracks your readiness over time. Also free, no credit card required.

What about FINRA’s official practice test?

FINRA hosts a full 75-question practice test on their site, free with a FINRA account. The pros:

• It’s official. Question style is the closest possible match.
• Weighted to the actual content outline.
• Free, no payment.

The limits:

• It’s a single static set. You see the same questions every time. After one pass it’s contaminated as a readiness signal.
• Explanations are thin. The answer key gives you the right letter, often without a full distractor breakdown.
• Update cadence is slow. Some items pre-date current rule changes (T+1 in May 2024, recent Reg BI guidance, Form U4 timeline updates).

Use it once, late in your prep, as a clean baseline.

Are Achievable and Knopman’s free exams worth it?

Both are full 75-question practice exams, free, written by people who teach the SIE. Honest read:

Achievable’s free practice exam runs in-browser, scores you at the end with section breakdown, and uses their own question writers. No email or credit card required to start, and progress saves automatically. The rest of the platform (textbook, 35+ practice exams, chapter quizzes) is paid at $99.

Knopman Marks’ free practice exam is a downloadable PDF (75 questions plus answer rationales) gated behind an email signup. The PDF format means no timer and no auto-grading; you mark answers manually. Knopman writes for a Wall Street audience and the exam reads slightly harder than average, which some candidates find useful.

STC does not publish a free full-length practice exam. Their free offering is an eBook study guide, plus 20-question progress quizzes inside their paid course. Skip STC if a free practice exam is what you want.

The shared limit across both Achievable and Knopman: each is a single static exam. Take it once, and you’ve burned that signal. They are best used as one-shot diagnostics, not repeat practice. The only free tool that gives you unlimited, freshly generated, exam-weighted practice exams is the CertFuel app, which draws from a 4,000+ question bank.

What about Kaplan’s free SIE prep?

Kaplan’s free tier is just an SIE Practice Question of the Day, one question delivered by email. There is no free full-length exam from Kaplan; that lives behind their paid course.

That makes Kaplan useful as a daily drip, not as a practice-exam source. Pair it with one of the full-length free exams above if you go this route.

Why are the user-uploaded free practice tests risky?

Quizlet, Reddit-shared sets, and AnkiWeb decks all offer “SIE practice tests” in some form. The same problems that hit free SIE flashcards hit free practice tests harder, because a wrong question in a test is worse than a wrong card:

• A wrong flashcard teaches you a wrong fact.
• A wrong practice question teaches you a wrong fact and a wrong way of reasoning about a scenario.

In our audit of community-uploaded SIE practice sets, roughly 15% of questions had a factual or reasoning error, and another 10% were stale relative to current rules. For specifics on how to evaluate a community set before trusting it, see Anki Decks for the SIE and Should You Use AI to Write SIE Practice Questions?.

How many full-length practice tests should I actually take?

For a 5-to-6-week study window, 3 to 5 full-length practice exams is the sweet spot. A reasonable rotation, given the free options:

1. CertFuel 80-question exam (week 2 or 3), as a baseline. Expect to score in the 50s. Use the per-question pass rates to find your weak sections.
2. Achievable free exam (week 4), after a heavy products section pass. Aim for high 60s to low 70s.
3. Knopman free exam (week 5), as a stretch test. Knopman’s question style is slightly harder.
4. FINRA official practice test (final week), as the cleanest readiness signal. Save it for last.
5. CertFuel app exams (any week), for unlimited freshly generated full-length exams between the static ones above.

Mixing sources avoids the “memorized this exam” problem and exposes you to different question voices. See How to study for the SIE for the wrong-answer review pattern that turns practice exams into score gains.

What score on a practice test means I’m ready?

The rough rule, supported by the first-time pass rate data:

• Below 65% on a recent full-length: not ready. Give yourself another 1 to 2 weeks.
• 65 to 72%: borderline. You can pass, but variance is wide.
• 73 to 79%: comfortable margin. Most candidates in this band pass on the first try.
• 80%+: very likely to pass. Stop over-studying.

Two caveats. First, difficulty calibration varies. Knopman’s free exam reads harder than FINRA’s; Achievable’s reads close to FINRA’s level. Take any single score as a noisy estimate. Second, two scores in the same band beats one score above the band.

The bottom line

Free, full-length SIE practice exams are not rare. FINRA, Achievable, STC, and Knopman each give you one, and any of them is a usable starting point. What’s harder to find: a practice exam you can take more than once, with per-question crowd accuracy, no signup, and content updated to current rules. The CertFuel SIE practice exam covers the no-signup, click-to-study version, and the CertFuel app gives you unlimited freshly generated exam-weighted practice exams (free, no credit card). Use the CertFuel exam early to surface weak areas, rotate through the vendor exams in the middle of your prep, save the FINRA official set for your final week, and use unlimited app-generated exams whenever you need a fresh signal.
