About ExamCores
ExamCores is an independent reference for IT certification exams — what each exam actually tests, what it costs, how long it takes, and which prep resources are worth your time.
What we cover
We currently document 32 exams across 6 vendors. Every exam page carries the same structure: the headline facts (cost, duration, question count, passing score, delivery options), the official domain breakdown with weightings, a prep guide, and a curated resource list. One page per exam, so you can read or Ctrl-F it in one go instead of stitching together five vendor pages and a forum thread.
Practice questions
Selected exams have a practice question set, organised by exam domain, with an explanation for every answer. Our editors write these questions to test the skills in the official exam outline. They are not real exam items. Practice questions are free to use on the site but may not be copied or scraped (see the terms).
Independence
ExamCores is not affiliated with, endorsed by, or sponsored by any certification vendor. Exam names, codes and badges are trademarks of their respective owners. We do not accept payment for inclusion, placement or positive coverage. Some resource links are affiliate links, which is how the site is funded — see the affiliate disclosure for exactly how that works and what it does not influence.
How we work
Facts come from the vendor's official exam page and current exam guide, and are checked by a human before publication. AI assistants help us draft and keep hundreds of pages consistent; they do not decide what we publish. Every exam page is stamped with the date a human last verified it. The full process is written up in our verification and AI disclosure.

Corrections
Exam prices, formats and retirement dates change without much warning. If a page is wrong or stale, the vendor's official page always wins — and we want to know. Send us the correction and we will re-verify the page.
