An honest, cited answer. We make no ROI, salary, placement, or 'worth it' claim, and we don't track live job demand — where we don't know, we say so.
You can retake it — under the vendor's retake policy. CompTIA's official policy: there's no mandatory waiting period between your first and second attempt, but before a third or any later attempt "you shall be required to wait for a period of at least fourteen (14) calendar days from the date of your last attempt." Once you pass, you can't retake the same exam version. What a retake costs is a separate question from whether you may sit one, and we have not surveyed retake pricing across vendors — check the specific exam's policy and your own purchase terms, since some bundles include a retake, before you budget for a second attempt. Practically: treat a failed attempt as a diagnostic — review the objective areas you were weak on, do more hands-on practice, and re-sit. Other vendors (AWS, Cisco, Microsoft, ISC2) have their own retake/wait rules, so check the specific exam's policy.
What we don't know
We make no pass-rate or 'X% pass on retake' claim. CompTIA's published retake policy does not address whether retakes are disclosed to employers, so we won't imply it either way; we have not reviewed other vendors' policies on that point.
