Prepare for the CDMP with a question bank built around the exam itself. DataMaster Prep is a focused practice app for the DAMA Data Management Fundamentals exam: 500 multiple-choice questions, every one with a written explanation, across all 14 DMBOK knowledge areas. WHAT'S INSIDE - 500 practice questions, each with an explanation of why the answer is right - All 14 knowledge areas — Data Governance, Data Architecture, Data Modelling & Design, Data Storage & Operations, Data Security, Data Integration & Interoperability, Document & Content Management, Master & Reference Data, Data Warehousing & BI, Metadata Management, Data Quality, Big Data, Data Ethics, Data Management Process - A mock exam that follows the official blueprint: 100 questions drawn at the real exam's weighting, 90 minutes on the clock — or 110, the allowance the CDMP gives when English is not your main language - Results graded the way the exam grades them — Associate 60%, Practitioner 70%, Master 80% BUILD THE QUIZ YOU NEED - Draw from everything, from questions you have not seen yet, from the ones that need work, or from your bookmarks - Choose the knowledge areas, the length and the question range - Time each question, time the whole quiz, or turn the clock off SEE WHERE YOU STAND - Accuracy per knowledge area, so revision goes where it is weakest - Sessions, average score, best score, answers given, day streak and a score trend - A mistakes bank that collects what you got wrong and hands it back as a quiz - Full history of every session, with every answer reviewable STUDY AND SEARCH Search the whole bank by wording or topic, filter by area, by bookmarked or by not seen yet, sort by best match, question number or weakest first — then practice the exact set on screen. Also: dark mode, an optional reveal-answer button, the extra-time setting for non-native English speakers, and a quiz that resumes where you left it. FREE TO TRY, ONE PAYMENT TO OPEN Every feature is free: mock exam, statistics, mistakes bank, bookmarks, search, history. What the free version limits is the question bank — you get 2 questions from each of the 14 knowledge areas, enough to see exactly how the app works. A single in-app purchase unlocks all 500 questions for good. It is not a subscription, nothing renews, and it restores on any device signed in to the same App Store account. YOUR ACCOUNT Sign in with email, Google or Apple. Your answers, scores and settings stay on your device. You can delete your account at any time from Settings — it takes effect immediately and your study data is erased with it. INDEPENDENT STUDY AID DataMaster Prep is not affiliated with, endorsed by or certified by DAMA International. The questions are practice questions written for this app, not past exam papers, and practising here is not a guarantee of passing.

Verdict

The call

ISC2 Official Exam Prep and DataMaster Prep are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
