The Capital Prep Method
What to study, when to study it & the exact moment you're ready.
Cut out the months of studying you don't need. OCN prep that adapts every day — no guessing what to do next.
SurePass readiness
A readiness score built from your own answers — not a progress bar. It moves as you answer, and recent work counts most. On an exam that reports a scaled score, it is the only straight answer you get to "am I ready?"

Questions, answered
What's inside the study portal?
The full Fast Track Study System — every practice question, every flashcard deck, full-length mock exams, narrated audio, Miles the AI tutor, and the entire study guide, every chapter readable and highlightable. The cheat sheet — the highest-yield facts as a PDF — is in the study portal on every pass, with instant access to download it. Every pass opens all of it, backed by the SurePass Guarantee.
How does the SurePass Guarantee work?
Score 85%+ 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 up to $420 toward your retake fee. You file the claim in your study portal with your official ONCC score report.
How many full-length mocks do I get?
Four scored full-length sittings, each a brand-new 165-question paper built to ONCC's six domains and timed to the real three hours. Practice questions and timed practice are unlimited and never use one. The pool is the whole 1,320-item bank, which is eight distinct 165-question papers' worth — so every sitting draws fresh. Springer's practice Q&A ships one form; ONCC's own paid practice test is a 100-item draw.
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, which matters here because ONCC certification renews every four years.
What does the exam itself cost?
$300 if you are an ONS or APHON member and $420 otherwise, paid to ONCC. A retake is the FULL fee again — ONCC's fee schedule has seven lines on it and not one of them is a reduced retake. You can retest once your current authorization expires, at most once per 90-day eligibility period, and after a third failure inside three years you wait a year. That is why our Lifetime tier covers up to $420 toward your retake fee if you qualify and don't pass.
What is on the exam?
165 multiple-choice questions in three hours, of which 145 are scored and 20 are unscored pretest items, with no scheduled breaks. Six domains: Symptom Management and Supportive Care is the largest at 25%, then Treatment Modalities at 20%, Oncologic Emergencies at 16%, Oncology Nursing Practice at 15%, Care Continuum at 14%, and Psychosocial Dimensions of Care at 10%.
What score do I need to pass?
ONCC reports a scaled score, not a percentage of questions correct, so there is no official percent cut to quote — including from us. The 85% our mocks score against is our own bar, stated as ours.
How many people fail the OCN?
ONCC publishes this itself, with raw counts, every year. Of 3,071 first-time candidates in 2025, 1,072 did not pass — more than one in three. Counting every candidate rather than only first-timers makes it worse, not better, at 39%. It is also the hardest of ONCC's exams: 61% passed the OCN in 2025 against 78% for AOCNP and 75% for CBCN.
What about ONS's own review courses?
ONS — the Oncology Nursing Society, the specialty society rather than the certification board — sells its OCN review as eight individual courses in two bundles, priced from about $35 to $140 each depending on membership. They are taught content with knowledge checks inside the lessons, they publish no question bank, they carry no guarantee, and access runs 180 days. They are a different job from this one, and a candidate who does both is better prepared.
ONCC sells retake insurance. How does that compare?
It is called DoubleTake: $100, bought at application time, and it pre-pays your second attempt. ONCC prices the value itself as "a savings of up to $320". It is nonrefundable if you pass, you have to decide before you have any information about whether you will need it, and it comes with no content, no questions and no guide. Our Lifetime tier includes that same retake cover, plus a full refund, plus the whole study system.
My employer is paying for the exam. Does the guarantee still matter?
Partly, and it is worth being straight about it. If you are going through ONCC's FreeTake program your employer is invoiced only when you pass and you already have one free retake, so the retake-fee half of our Lifetime guarantee is worth nothing to you — the refund half still is. If your employer reimburses you for a fee you paid, the retake cover pays on your receipt as usual.
Am I eligible to sit the OCN?
ONCC requires an active unencumbered RN licence, two years of RN experience within the last four, 2,000 hours of adult oncology nursing practice within the last four, and 10 contact hours of oncology continuing education within the last three. Check ONCC's current requirements before you apply.
What happens when my pass expires?
Your account stays; the paid features stop. Your notes, highlights and flashcard history are all still there if you come back, and Lifetime never expires.
Are the questions like the real exam?
Every item is written to ONCC's 2026 content outline, weighted domain by domain, with four options and a rationale on each — the same flat four-option format ONCC uses. Every key was recomputed from its own stem before the explanation was read. What we will not do is claim a number we have not measured: where we have run a construction audit we publish it, and on this bank it did not come back clean, so no page here claims that it did.
My exam date moved. Does the plan adjust?
Yes. Change the date and the Game Plan rebuilds around the new one — it works backwards from your date, so a move forward compresses it and a move back spreads it out. Nothing is lost.
Can I use it on my phone, and does it work offline?
Yes to both. Add it to your home screen and it behaves like an app. Your due flashcards and a set of practice questions download automatically, so you can revise with no signal. The whole study guide downloads too, narrated audio included; scored mocks and the tutor still need a connection.
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.
Why are SurePass guarantees limited?
Because we honor them. Every guarantee is a real financial commitment we may genuinely pay out, so a limited number opens for this exam each day. The allocation resets at midnight in your own time zone, and the counter shows how many of today's are still open.
Have questions or concerns?
A real person reads every message and replies by email.
