The Capital Prep team, ready to answer your question

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 your full $260 retake fee. You file the claim in your study portal with your official ASCP score report.

How many full-length mocks do I get?

Four scored full-length sittings, each a brand-new 100-question paper weighted across all seven disciplines and timed to the real 2 hours 30 minutes. Practice questions and timed practice are unlimited and never use one. The pool is the whole 847-item bank, which is eight and a half papers' worth, so every sitting draws fresh.

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 afterwards — Lifetime, and on this exam that is a real difference: the category's default product is an annual subscription that stops.

What does the exam itself cost?

$260, paid to ASCP BOC, non-refundable, and a retake is the full $260 again — there is no reduced re-sit line anywhere in ASCP's fee schedule. That is why our Lifetime tier covers your full $260 retake fee if you qualify and don't pass.

What is on the exam?

100 questions in 2 hours 30 minutes. Seven disciplines, and four of them carry 19% each — Blood Banking, Chemistry, Hematology and Microbiology — with Urinalysis and Other Body Fluids, Immunology and Laboratory Operations at 8% each.

What score do I need to pass?

ASCP reports a scaled score, and in 2025 MLS scores ran from 100 to 895 with a mean of 462. A scaled score is not a percentage of questions correct, so nobody can honestly convert it into one — including us. The 85% our mocks score against is our own bar, stated as ours.

How many people fail the MLS exam?

ASCP publishes this itself, per credential, per year, back to 2007. In 2025, 5,873 people sat MLS and 69% passed — so nearly one in three did not. The number that matters more if you have already sat it: of those who went back and retook it that year, 58% failed again.

What about ASCP's own study materials?

ASCP BOC sells its own, from about $59 to $249 depending on the package, with a question bank larger than ours. They come from the body that writes the exam, which is a real advantage no third party can claim. They carry no guarantee of any kind. They are worth having, and they are a different purchase from this one.

Am I eligible to sit the MLS exam?

ASCP has several eligibility routes, based on your degree, your clinical laboratory training programme and your work experience. Check ASCP BOC's current eligibility routes before you apply — they are specific and they change.

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 ASCP BOC's own content guideline, weighted discipline by discipline, with four options and a rationale on each. 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.
