ExamFX is a licensing-education company: structured online courses with video lectures, practice and benchmark exams, textbooks, instructor support, and live webinar options, sold per exam with 90- to 180-day access — often through a sponsoring firm. Trelos is a complete daily study system built on retention: it teaches every concept, drills it the way FINRA words it, and schedules review so the lookalike rules stay distinct through test day. It does not include video lectures, instructor support, or full-length timed finals.
ExamFX packages, per its own pages, bundle an eBook and hard-copy textbook, on-demand video lectures, a personalized study plan, practice question sets, checkpoint exams, a benchmark final and standard finals, a custom exam generator, flashcards, and instructor support by phone and online. Listed prices as of November 2026: Series 65 at $240 (textbook package, 90 days), $275 (online course, 180 days), or $375 (live online, 180 days); the SIE + Series 7 bundle at $449 (online) or $628 (live online), both 180 days. ExamFX's pass-guarantee page says its guarantee currently covers insurance courses only. Packages for other exams are on ExamFX's securities pages.
Trelos is a mobile-first retention engine with a separate track per exam: SIE, 249 questions across 35 concepts in FINRA's four sections; Series 7, 270 questions across 43 concepts with options and suitability weighted the way the exam weights them; Series 6, 186 across 31 concepts; Series 63, 168 across 28; Series 65, 200 across 33; Series 66, 236 across 39. Every concept: guess first, short lesson, practice, scheduled review, with confident mistakes returning first. Standard multiple choice. Each track covers its exam's full content outline on its own; Trelos does not include video, live instruction, or full-length timed finals.

Choose ExamFX if your firm provides it, you want instructor access, or you need full-length timed finals to rehearse the real sitting — none of which Trelos includes.
Choose Trelos if the content is what leaks: exclusion versus exemption, share-class rules, option breakevens that blur between sessions. The Series exams are won on precise recall under one-word swaps, and spaced review is the mechanism that protects it — in sessions short enough to fit around a training program's hours.
A full course with instructor support is worth its price for candidates who need structure and have a firm paying. What no course controls is whether week two is still there in week eight — the exact failure mode of the Series 65's legal distinctions and the Series 7's options math. Trelos is built for that, and for the self-funded candidate on the SIE or Series 63/65/66, it's a complete preparation at a fraction of a course's price. Try the free topics in your exam's track; if the method holds, one payment buys 12 months, extended free if you meet the guarantee's conditions and don't pass.
Pass guarantee: learn every concept in your track and keep up your scheduled reviews, and if you still don't pass, your access is extended free — three more months per attempt — until you do. It's an extension, not a refund.
