Certification practice — free, in your browser
AWS Cert Master is an unofficial study tool for AWS and CompTIA certifications: exam-style practice tests, domain-weighted question pools, progress dashboards, and acronym drills for CompTIA (a prep mode most tools skip). No account or install required.
How to use AWS Cert Master
- Pick a certification from Browse certifications in the menu or on the home page.
- Review exam domains and optional settings in the menu (timer, feedback on Next, doc links).
- Start a practice exam — each attempt draws a new random set weighted like the official exam guide.
- Submit and review your score, domain breakdown, study plan, flagged questions, and drill mode for weak topics.
- Track progress on the dashboard; export or clear your data under My data in the menu.
- CompTIA only: use Study acronyms on the exam page to drill abbreviations both ways before a full practice test.
Progress is saved in this browser only. Use Export backup before switching devices. Practice questions are not copied from real AWS exams.

AWS Certified Cloud Practitioner
CLF-C02
Each attempt draws random questions from the bank using official exam domain weights, with shuffled order and answer choices. No account required.
CompTIA acronym prep
CompTIA exams use heavy shorthand (ports, protocols, roles, attacks). Our acronym quiz trains both directions—term to meaning and meaning to term—so stems on the real exam feel familiar.
