Questions, answered
Can I study without an internet connection?
Yes. Open your flashcards once while online and your due cards download to your phone automatically — no button to press. Practice questions download too. You can then review with no signal at all, and everything you answer saves on your device and syncs the moment you're back online, even if you closed the app in between. The whole study guide downloads too, narrated audio included; scored mocks and the tutor are the two things that still need a connection.
Is there an app to download?
There's nothing to install from an app store. Open Capital Prep in your phone's browser and add it to your home screen — on iPhone that's Share → Add to Home Screen, on Android it's the Install prompt. It then opens full-screen like any other app, takes up almost no space, and is always the current version because there's nothing to update.
What do I get for free?
The full Fast Track Study System, free for 24 hours with no card — every practice question, every flashcard deck, Cram Mode, Focus sessions, narrated audio, a full-length mock exam sat as timed practice, your own flashcards from any highlight, and the entire study guide, every chapter readable and highlightable. Instant access to download the full cheat sheet. Your cheat sheet always stays yours. A pass keeps all of it open, backed by the SurePass Guarantee.
How does the SurePass Guarantee work?
Score 80%+ on one full-length mock, sit the real exam, and if you don't pass we refund what you paid. On Lifetime, clear two mocks with your readiness meter at "Getting close" or above and we also pay your full $177 retake fee. You file the claim in your study portal with your official score report.
Do I need the SIE or a sponsor before the Series 66?
No prerequisite and no sponsor needed to sit it — the Series 66 is a NASAA exam you can register for yourself. But your 66 registration only becomes effective once you also hold the Series 7, so most people prep the two together. We cover the Series 7 as well, and the 66 already includes everything the Series 63 tests — you don't need both.
Which pass should I buy?
Match it to your exam date. Sitting within a week, the 7-Day Pass is built for that. A month out, the 30-Day. No date yet, or you want it to keep working after you pass — Lifetime.
What happens when my pass expires?
Your progress is kept. You can upgrade at any time and pick up exactly where you were — and upgrades always credit what you already paid.
Are the questions like the real exam?
They're written to NASAA's Series 66 test specifications and weighted to its four areas, so a mock is the same shape as the real thing: 100 scored questions, 150 minutes, 73% to pass.
My exam date moved. Does the plan adjust?
Yes. Change the date and the plan rebuilds around your new one.
Can I use it on my phone?
Yes — everything syncs across devices, and the reader, flashcards and practice all work on a phone.
Why are SurePass guarantees limited?
Because they're real commitments — every guarantee is a refund — and on Lifetime a retake fee — we may genuinely pay out, so we underwrite 25 of them each week for the Series 66. If a week's allocation is claimed, buying still works: your guarantee simply activates the following Monday, when unclaimed spots reset.
Can I bundle exams and save?
Yes — that's the Bundle & Save builder. The Series 66 pairs with the Series 7 — its co-requisite — with or without the SIE, and a tiered discount applies to every course: 15% extra off a pair, 30% off three, stacked on current prices. Every bundled course is Lifetime access, each with its own SurePass Pro guarantee.
How does the guarantee work on a bundle?
Every course in your bundle carries SurePass Pro. Qualify on the course you sat (80%+ on one full-length mock), and if you don't pass, you're covered — a refund, plus retake-fee reimbursement on Lifetime once you clear two mocks with your readiness meter at "Getting close" or above: up to the official retake fee of the most expensive exam in your bundle, in total. Refunds are per course: the exam you didn’t pass is refunded, the rest of your bundle stays yours.
Do you offer refunds if I change my mind?
Yes, separately from the pass guarantee: 24 hours on the 7-Day Pass, 48 hours on the 30-Day Pass, or 72 hours on Lifetime, measured from your purchase (or from your upgrade, if you upgraded) — no questions asked, as long as you haven't sat your exam yet. EEA and UK buyers also keep their 14-day statutory right. The SurePass Guarantee is the other promise — that one is about your exam result, not about changing your mind.
