FAQ

Questions

What's the difference between Core and Complete?
Both tiers include all 44 cheat sheets as downloadable PDFs and browser-viewable web pages, organized by all 7 CMD domains. Complete adds web access to all 440 practice questions — 10 questions per topic sheet, across every domain. Quizzes are web-only and cannot be downloaded.
Are the quizzes downloadable?
No — quizzes are web-only to protect content integrity. The cheat sheet PDFs are fully downloadable in both tiers.
Who wrote this material?
Precision Prep was created by a CMD-credentialed dosimetrist with clinical training at Memorial Sloan Kettering. All content is original — not scraped from online forums or test banks — and aligned to the current MDCB blueprint.
Is this a subscription?
No. It's a one-time payment with lifetime access to everything included in your tier at the time of purchase.
What if I want to upgrade from Core to Complete later?
Email us at precisionprepcmd@gmail.com and we'll apply a $100 upgrade credit — you pay only the $100 difference.
What format are the cheat sheets?
PDF downloads organized in domain-based ZIP files (e.g., DomainIII-Quizzes.zip). You can also browse every sheet directly in your browser from the member dashboard without downloading anything.
Is there a refund policy?
Because this is a digital product with instant access, all sales are final. If you have a problem with your purchase, email us and we'll make it right.
