The free path, in order
1. Start from the exam objectives / outline — it is the scope the certifying body itself publishes, and where a vendor also publishes domain weightings they are in it. It may not be a comprehensive list of every exam topic. Study against it, not against a course's table of contents. Where the entry below records an exam version RoleMath has not verified as current, confirm on the vendor's page that you are reading the outline for your exam before you study against it.
2. Free course material is listed above, but RoleMath does not count it toward a complete free path — our last check did not confirm that any of it is current for this exam version, reachable without an account, and inside our re-verification window. Use it for instruction where it helps, and treat the exam objectives as the authority on scope.
3. Free study lowers what you spend preparing, not what the exam itself costs — verify the current price on the vendor's official exam page before budgeting.
Free resources reduce what you spend to study. No resource guarantees a pass, and a course is not the certification.
