Where each one wins
- Cheapest well-reviewed full course: Achievable at $99 with 12 months and a money-back guarantee.
- Live instruction: Kaplan Premium Live Online and Knopman’s upper tiers include instructor-led sessions; you pay for it.
- Guarantee-driven buyers: read the fine print. STC and PassPerfect guarantees apply only to specific tiers and require minimum practice-exam scores; Kaplan shows none for securities exams.
- Where we fit: lowest price ($39 for every exam), 12 months plus a free extension until you pass, and bundles priced for the full path. We do not offer video lectures or live classes, and our question bank is new.
How to choose
- If your firm pays, use the firm’s provider. Many sponsors have a standard vendor.
- Self-funding? Compare total cost for your full path, not one exam. A broker path is three exams (SIE + 7 + 63).
- Access length matters if your exam date might slip: 5-7 months vs 12.
- Test the questions first. Every vendor here offers free samples; try ours on the free practice test.
