Already opted in? Keep using the full free bank — Premium is an upgrade, never a wall in front of what's free.
Everything in the free tier stays free. Premium layers a study engine on top of it.
The engine keeps bringing back what you miss and eases off what you've mastered, scheduling each question for the moment you're about to forget it.
One tap pulls up exactly your weak questions, or the hardest items in the bank, so every minute lands where it counts.
A single number blends your coverage, accuracy and mastery so you know — honestly — whether you're ready to sit the exam.
An ordered, always-current plan that tells you the next best thing to do, based on where you actually stand today.
Follow the plan and we stand behind it. If you don't pass, you don't pay — full terms below.

We built Premium to get you to a pass, and we'll stand behind it. Study with Premium, work through your study plan, and reach the readiness score we call a green light. If you then sit the SIE and don't pass, send us your result and we'll refund your Premium purchase in full.
It's a study aid, not a shortcut — the guarantee asks that you actually do the work (complete the plan and a full timed mock at the green-light threshold). Full conditions are on our Terms page. Independent of FINRA; passing is never guaranteed by any provider, which is exactly why we put our money behind the work instead.
One payment, lifetime access for the SIE, eBook included.
