PrepWiz: AWS, PMP & SQL Prep

craftcode

About this app

PrepWiz is a certification exam prep app for people who want to pass on understanding, not luck. Most quiz apps just reward you for spotting the right letter. PrepWiz trains the harder skill real exams test: telling apart answers that look almost identical, so you stop falling for the traps that quietly cost you points.

Here's the difference. Tap to answer, and hold when you're sure. If you're confidently wrong, PrepWiz flags it as a priority misconception and brings it back for review — because the answers you're most certain about, and still get wrong, are the ones that sink your score on exam day. That's the whole idea behind PrepWiz: learn why wrong answers feel right.

WHAT YOU CAN PRACTICE

• AWS Cloud Practitioner practice test questions covering cloud fundamentals and all four CLF-C02 exam domains.
• PMP exam questions plus a focused Scrum quiz across project management essentials, Scrum, and modern agile delivery.
• SQL practice questions on relational modeling, joins, transactions, and query performance.
• UI/UX design questions spanning user research, interaction design, accessibility, and product judgment.

Every question comes with a clear explanation, the trap to watch for, and a quick memory hook — so a wrong answer turns into something you actually remember.

TRACK REAL PROGRESS, NOT JUST A SCORE

• See your accuracy, attempts, and the categories you need to shore up.
• Watch each category move from new to fragile, learning, and strong as you practice.
• Replay your "confident misses" or run a fast 10-question mixed set whenever you have a few minutes.

BUILT TO RESPECT YOU

• No account and no sign-up.
• No ads, no tracking, no analytics.
• Works offline — your progress stays on your device.

Whether you're studying for the AWS Cloud Practitioner exam, working through PMP exam questions, brushing up with a Scrum quiz, or sharpening your SQL practice questions, PrepWiz turns everyday practice into real exam readiness — one confident answer at a time.

Download PrepWiz and start practicing the difference between the answer that looks right and the one that is.
