Best free SIE exam prep: the honest 2026 list

The disclosure first: we make Passline, one of the resources on this list, so apply whatever discount you think that deserves. The reason this page exists is that "free SIE prep" searches mostly surface pages that are free the way a car dealership test drive is free: a small sample attached to a sales funnel for a $99 to $895 package. Genuinely free resources exist. Here is the honest map of them, and the traps to watch for.

What counts as free here

Three tests. No card and no purchase, ever, not a trial that converts. Enough volume to actually prepare with, not a taste. And current content, because the SIE changes: the outline is specific, and materials written before May 2024 still teach T+2 settlement when the exam now tests T+1.

1. FINRA's official practice test

Start here, because it comes from the people who write the real exam. FINRA publishes a free SIE practice test with 75 multiple-choice questions in the style of the live exam, untimed, with feedback at the end. It is the single most authoritative free resource in existence, and every candidate should take it. Its limit is volume: it is one test. Once you have seen those questions, it has told you everything it can, and one exam's worth of questions is nowhere near enough repetition to train on.

2. Passline (ours)

This is the resource we make, so verify everything with your own eyes. Passline is a full SIE prep platform that is free with an account: 1,600+ original questions written to the current outline, every answer choice explained on every question, unlimited full-length 75-question simulated exams weighted like the real thing, mastery diagnostics, a study plan built from your test date, interactive labs for options and bond math, and flashcards you can sample without even signing up. No card, no trial clock, no paid tier hiding the good questions. You can try three sample questions with full explanations before creating anything. Why free? Short version: we would rather be the platform everyone used than the one a few people paid for, and we explain the model here.

3. Free samples from the paid providers

Most paid providers offer some free content: sample question sets, trial chapters, or demo exams. Treat these as taste tests, because that is what they are designed to be. They are useful for judging whether you like a provider's question style before spending money, and taking two or three different demos is a fine way to see varied question craft. Just know the volume is capped on purpose: the free layer exists to sell the $99 to $895 package behind it. If you are deciding whether one of those packages is worth it, we wrote verified-price comparisons of Kaplan, STC, ExamFX, and Knopman Marks.

4. YouTube and exam communities

Free video explainers cover nearly every SIE concept, and exam communities on Reddit are full of recent test-takers describing what studying actually took. Both are genuinely valuable and genuinely free. Their weakness is structure: a playlist cannot tell you which of the four sections is dragging your score down, and a thread cannot quiz you. Use them to shore up concepts you have already identified as weak, not as the backbone of your prep.

The traps in free material

Three things to check before trusting any free resource, including the ones above. First, currency: if a question teaches T+2 settlement or pre-2024 rules, the whole source is suspect. Second, answer quality: free question dumps floating around the internet are full of wrong answer keys, and a wrong key is worse than no practice at all. Third, the bait-and-switch: pages advertising a free exam that turns out to be ten questions and an email capture form. Free that cannot explain WHY an answer is right is not preparing you; the explanation is where the learning happens.

The bottom line

A complete free stack exists in 2026: FINRA's official practice test to calibrate, a full free platform to drill on, and YouTube plus communities to patch concept gaps. The $100 you must spend on the exam fee is real; the $99 to $895 on prep is now optional for self-directed studiers. If you want to test that claim, create a free account, take a full simulated exam, and judge the free stack by your own score report.
