Is this certification actually worth it? We built WikiCerts to answer that honestly.
WikiCerts is an independent guide to IT and professional certifications. We explain what each exam covers, what it costs, how to prepare and what it can do for your career, and we link every figure back to where it came from.
What we cover
For each certification we aim to answer four questions a candidate has before committing time and money:
- What does the exam test, and in what format?
- What does it cost, and how long is it valid?
- How should I prepare, and roughly how long will it take?
- Which roles use it, and what do people holding it typically earn?
Where we do not yet have reliable information for one of these, the page says so instead of guessing.
Where our data comes from
| Information | Source |
|---|---|
| Exam format, fee, duration, passing score, validity, prerequisites | The certifying body's official exam pages and exam outlines |
| Exam domains and study plans | Built from the official exam outline |
| Salary ranges | Public salary sources, named on each salary page; shown as ranges, not guarantees |
| Practice questions | Written originally to match the published domains; never copied from real exams |
How pages are written
Guides are drafted by our editorial team, sometimes with the help of AI writing tools. Every draft is checked for specific claims (fees, question counts, durations, scores and dates) against the official source before it is published, and anything we cannot verify is rewritten in general terms or removed.
Vendors change exams and prices without much notice, so each certification page links to the official page. Please confirm the details there before you book.
Independence
WikiCerts is not affiliated with, endorsed by or paid by any certification vendor. Certification names and trademarks belong to their owners and are used only to identify the exams we describe.
Corrections
If you spot something out of date, we want to fix it. Exam details are reviewed when vendors publish changes, and corrected pages show an updated date.
